1. Introduction：
The GG-001B irrigation system is a highly effective intelligent irrigation system; it
includes: moisture sensor, with controller, solar cell and battery, and latching magnetic
valve.
This system is solar powered, plug and use, dramatically reduce labor and water usage
with this system.
This system is housed in an ASA plastic shell, which features weather and solar
resistance, and is rugged for outdoor usage. The system is great for garden, backyard
vegetables, nursery and agriculture.
2. How it Works
Moisture data is collected data from soil and sent to the microcontroller. The controller
compares the moisture level to the user’s preset wet/dry levels to decide if irrigation is
needed. The controller opens the valve to irrigate when the sensor reaches the dry
level, and closes the valve when the wet level is reached.
3. Specifications：

Quiescent current: ＜150uA
Sampling period: irrigation off: moisture sensor samples every 30 minutes, irrigation
on: moisture sensor takes samples every 5 minutes. Controller shows updated
moisture reading after every sample. Moisture readings are relative percent.
Latching magnetic valve (supplied), specifications: Pulse V 5-9 VDC, Power 5.5VA,
Width of pulse 20 – 100mS: water pressure 0.5-10bar
Recharge time: Low batteries may cause a new system to not turn on. Place the solar
powered controller under sun for 10 hours to recharge the batteries, and then turn
power on.
Fully charged batteries can maintain system operation for up to 15 days in darkness.
4. Special terms:
Dry set level. Soil dry point, when soil moisture sample level is at or below this level,
the system will start irrigation. This level is user determined, expressed as a percent
range is 1 to 99%.
Wet set level: Soil wet point, when soil moisture sample level is at or above this level,
the system will stop irrigation. This level is user determined, expressed as a percent
range is 1 to 99%.
Disable Irrigate: This is the period in time where no irrigation will occur, even if the
soil moisture is lower than the dry set level. Use this to set the calendar for forbidden
periods of operation, for either when irrigation is not desired, other zones are being
irrigated, or water saving ordinances prevents watering.
5. Installation:
Please connect the system according to following instructions.
1. Open the package. Remove all the parts, Fig. 1.

11. Choose the installation location; lay out water pipes, if necessary. Arrange and
install sprinklers, if necessary, and connect the magnetic valve between the water
source and irrigation pipes. Observe the direction arrow on the valve and make sure to
install the valve so the water flows in the direction indicated. The valve requires a
minimum pressure to operate properly, keep pressure above about 5psi, 1/3
atmosphere. Place the controller in a location where it will be under full sun.
Insert the moisture sensor in the representative
soil. The moisture sensor may be installed
horizontally, vertically, or at any angle between.
It should be buried to a depth, or make sure the
moisture sensor is been covered by soil at least 5 cm deep, where the wet level of the
soil is to be measured.
Connect the magnetic valve to the controller as shown on the illustration Fig11.
If there is debris in the water, it is suggested to filter the water before the valve.
If the region where the system is installed may freeze, preventive measures must be
taken, such as mounting the valve inside a box underground, or covering the valve
with a box. If there is a possibility of Rodents or other creatures to cause damage to
exposed wires, place the wires in a jacket, such as a PVC pipe. For maximum lifetime
of the wires, cover them to protect them from moisture and solar damage.
If the pressure surges when an automatic valve is used, a pressure relief valve and/or a
surge damper may be required.

6. Operation:
For a newly installed system, perform the following test prior to irrigation setup:
1. Verify the controller is installed solidly at a location of full sun.
2. See the illustration below for key locations. Push “Power” key on the controller,
holding for three seconds, to power the system on. The controller will beep three times.
Push “Manual” key to open the valve, there will be a click from the controller relay
and a snap from the valve, the LCD will show “Irrigating”, the water valve should
have opened normally.
3. Then push the “Manual” key again, there is a snap again, the word “Irrigating”
will disappear on the LCD. Verify the valve is closed.
4. Verify the moisture sensor is at the proper location to sense the desired soil
moisture. For proper continued operation, make sure the moisture sensor and irrigation
maintain the distribution of water and soil structure as existed when the system is
setup.

6.1 How to turn on power:
Push power key for 3 seconds, the controller will beep three times, LCD will show
operating information, and power is on.
After power on, the system will check if the moisture range as set, is effective (Wet
control level ≥Dry control level). If not, the display will show “ Failure,” beep two
times every 3 seconds, and simultaneously show these Dry/Wet levels on the LCD.
After setting the correct Dry/Wet control levels, the failure word will be automatically
deleted.
System also will check if there is an effective connection with the moisture sensor. If
there is no signal from the moisture sensor, “Failure” and “--%” will show on the LCD,
and a beep two times every 3 seconds will be heard, until the moisture sensor is
connected, then the system and LCD both will return to normal.
The system checks if the setup moisture control levels are correct first, then checks the
moisture sensor connection, if correct, the system operates normally.
6.2 How to turn off power:
Push the power key for over 3 seconds, the controller will beep long once, the LCD
will blank, and power is now off.
When collecting moisture samples, system will check the setup Dry/Wet control levels

ANC Technology
12
and the moisture sensor connection. If there is a problem, the valve will be closed first
then “Failure” will show on the LCD.
During the time to turn off power, the system will close the valve first, if it is
irrigating.
6.3 Manually open/close valve
At any time, pushing the manual key inverts the valve status. If push “Manual” key to
open the valve, the system will hold the open status until a second push of the manual
key. “Auto” will disappear; “Irrigating” will flash every 3 seconds (to show a
difference from the “auto” status). Moisture sensor will sample soil moisture every 5
minutes. Push “Manual” key again will close the valve, flashing word “Irrigating” will
disappear, “Auto” word comes back on the display, the system returns to automatic
operation. If push “Manual” key to close the valve, the system will back to
automatically without second time push “Manual” key.
Note: The system remains manual after first hit of the “Manual” key, not
returning to automatic until user second time pushes “Manual” to open/close the
valve again.
6.4 Auto Irrigation
After installing, the system is ready to be set up for automatic irrigation as described
below. During the period of no irrigation, the LCD shows “Running”, and rolls to
current moisture % (This moisture sensor reading is for reference only, not for
calibrated readings), then shows the set Dry control level and set wet control level.
System will collect soil moisture samples every 30 minutes; will open the valve if
analysis of the data requires irrigation. During an irrigation period, the LCD will show
“Irrigating”, and sample soil moisture every 5 minutes. If the result of data analysis
requires an end to irrigation, the system will close the valve, the word “Irrigating” will
disappear from the LCD.

6.5 Sleep
Sleep is a safety mode to make sure that irrigation does not become stuck on. The
system can operate from a fully charged condition for 15 days in a darkened condition,
which is not likely to happen. The System will check the battery voltage, when battery
voltage falls to 6.7 to 6.9V, the system will go into sleep mode, the LCD will be
blanked, if the system is irrigating, it will cease irrigation, and wait until the sun
recharges the battery. At that time, the system will automatically wake up and return to
normal operation. During the sleep period, the user only can turn off power to close
the system.
If the battery continues to drain to 6.3 V, the system will turn from sleep to off, to
prevent further battery discharge. After turning the power off, the charging circuit will
continue to work when the sun comes out, but user must turn on the system by
pushing the power key.
7. Set up
Note: Setup must be performed before attempting to allow automatic operation.

7.1 How to set up Dry/Wet moisture control levels
Notes：
1. Before learning dry/wet settings, finish system installation and make sure to verify
it first.
2. After learning wet/dry levels, do not move the moisture sensor, so the original
conditions are kept. If the moisture sensor must be moved the wet/dry levels may need
to be adjusted, if so, learn the dry/wet levels again.
When “Learning” is flashing, push “ENT” to show the submenu:
Use the up/down key to cause an icon, which represents an item to set up, to flash, and
then select the item by pushing the, “ENT”, Enter key to setup (Details see following).

3. Under “Learning” menu, push up/down key until “Dry Level” is flashing on the
LCD. Push “ENT” to confirm, then the “dry” words will no longer flash. The current
moisture % will show on the LCD as on following illustration, the moisture % shown
will probably be different.
Push “ENT” for the system to learn the level, two beeps will be sounded by the
controller, meaning the dry level has been learned. The system returns to the previous
menu. The up/down key can be used now to proceed to setting the wet level, or the
system will return to normal operation after 20 seconds.
7.1.2 Learn Wet Level
For first time setup or to reset the wet dry level follow these steps:
Judge the current soil moisture to determine how to proceed:
1. If need to increase the wet level %, go to case A.
2. If current moisture % is what is required, go to case B.
3. If need to reduce the wet level %, go to case C.
Case A, To increase the wet soil level from the present value:
This step assumes the moisture sensor is in soil that has been determined to be not
“Wet” enough. Under “learning” submenu, use up/down key until “Wet Level” are
flashing. Push “ENT”, the words will stop flashing. The LCD shows current relative
soil moisture %, this is the reading, which will be increased by opening the irrigation
valve. Push “manual” to open the irrigation valve, Let the system operate to irrigate
until the desired soil moisture is reached, a sample LCD illustration is shown below.
The system is not controlling the soil moisture; the user must stop irrigation at the

16
desired level. Irrigation could continue until the batteries run down, or could be up to
24 hours.
When the correct wet level has been reached, as determined by experience or
calibrated soil moisture readings, the new wet level is ready to be set. Push “Manual”
key to close the valve, push “ENT ” to learn the new wet level, two beeps will be
heard, meaning the controller learned the new wet level successfully, the system
returns to previous menu, and will exit in 20 seconds, if no other key is pushed.
User also can reference 7.2 to adjust wet control level on the LCD.
Case B To learn the present wet soil level:
This step assumes the moisture sensor is in soil that has been determined to be “Wet,”
which is sufficiently irrigated. Push “Set,” use up/down keys to browse to “Learning”
submenu, then browse to flashing “Wet Level”, push “ENT” to set wet level. Then
words “Wet Level” will no longer flash, current relative moisture % will be shown:
The wet soil moisture level will now be learned. Push “ENT” for the system to learn
the level, two beeps will be sounded by the controller, meaning the wet level has been
learned. The system returns to the previous menu and will exit after 20 seconds. Or
reference 7.2 adjusting wet control level on the LCD.
Case C: Push power key to turn off GG-001B. Wait until the wet moisture level is
reached. Then set the wet level as Case B.
Note: The purpose of learning Dry/Wet control levels directly from field is to
make the control levels as close as possible to the real field situation and better
