NOTE: This equipment has been tested and found to comply with the limits for a
Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are
designed to provide reasonable protection against harmful interference in a
residential installation. This equipment generates, uses and can radiate radio
frequency energy and, if not installed and used in accordance with the
instructions, may cause harmful interference to radio communications. However,
there is no guarantee that interference will not occur in a particular installation.
If this equipment does cause harmful interference to radio or television reception,
which can be determined by turning the equipment off and on, the user is
encouraged to try to correct the interference by one or more of the following
measures:
--Operate the system with the moisture sensor stakes fully inserted in the ground.
-- Reorient or relocate the receiving antenna.
-- Increase the separation between the equipment and receiver.

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：
Included with the GG-001B:
Solar Powered Controller, GG-001B-E
Soil Moisture Sensor, GGS-01A
Valve, 1” NPT low power latching
Long Extension Tube
Short Extension Tube with Stake
Battery Pack
Operating Manual and DVD
NiMH Battery pack: 7.2V, 800mAh
Solar cell V: 9.2V/120mA

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.

Fig. 1 Fig. 2
2. Assemble the tube and the stake as in illustration Fig. 2.
3. Magnetic valve cable and moisture sensor cable are protected by a grommet, Fig. 3.
Pass the valve cable through the grommet; the valve connection must pass through the
grommet leading away from the controller.
Fig. 3 Fig. 4
4. Slide the two cables through the tube from the slotted end, Fig 4.
5. Install the batteries by connecting the mating connectors on the battery to the
controller; tighten the retaining nut on the connector, Fig. 5.

6. Connect the mating connectors of the moisture sensor to the controller. Tighten the
stain relief nut, Fig.6.
7. Thread the tube into the female insert on controller, and tighten, making sure the
cables do not bind in the shaft, Fig. 7.
Fig. 7 Fig. 8
8. Push the grommet containing the cable bundle into the U shaped notch, Fig 8,9.
Fig. 9 Fig.10
10. Thread the extension tube onto the main tube. This completes the hardware
assembly.

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.
