GETTING STARTED
1. Remove the battery door.
2. Slide the [ CHANNEL ] slide switch to choose a channel.
3. Insert 2 x AA size batteries into the battery compartment according to the polarity
mark on the battery compartment..
4. Close the battery door.
5. After inserting batteries, the transmission status LED will light up 1 sec.
NOTE:
- Ensure to assign dierent channels of dierent sensors, in case you need to pair more
than one sensors.
- Once the channel is assigned to a Wireless Soil Moisture & Temperature sensor, you
can only change it by removing the batteries or resetting the unit.
- Avoid placing the sensor in direct sunlight, rain or snow.
PAIRING THE WIRELESS SENSORS WITH THE CONSOLE
The console will automatically search and connect to your wireless sensor(s). Once
your sensor(s) pair up successful, the sensor(s) signal strength indication and weather
information will appear on your console display.
NOTE:
During signal transmission, the LED indicator of the sensor will ash.
TEMPERATURE DISPLAY
On the display of the console which the soil sensor is linked to, temperature reading will
be displayed.
SOIL MOISTURE DISPLAY
Soil moisture can be claried into 5 dierent levels: Very Dry, Dry , Moist, Wet and Very
Wet.
To determine the moisture of soil, the sensor calibrate the moisture into 16 points, and
correlate them into percentage value:
Points Percentage Level
1 0%
Very Dry
27%
3 13%
420%
527%
6 33%

7 40%
8 47%

Moist11 67%
12 73%
13 80% Wet
14 87%
15 93% Very Wet
16 99%
NOTE:
The measurement accuracy of the sensor can be aected by the soil condition. For
example, the loose soil may get lower moisture level that compare with the dense soil.
