User Manual
Thank you for selecting this Wireless Soil Moisture & Temperature sensor.
This manual is used for AU version. Please read the instructions carefully
according to the version you purchased and keep the manual well for future
reference.
IMPORTANT NOTE
- Read and keep these instructions.
- Do not cover the ventilation holes with any items such as newspapers, curtains
etc.
- Do not clean the unit with abrasive or corrosive materials.
- Do not tamper with the unit’s internal components. This invalidates the
warranty.
- Only use new batteries. Do not mix new and old batteries.
- Do not dispose of old batteries as unsorted municipal waste. Collection of such
waste separately for special treatment is necessary.
- Attention! Please dispose of used unit or batteries in an ecologically safe
manner.
-Technical specications and user manual contents for this product are subject
to change without notice.
CAUTION
- Danger of explosion if the battery is incorrectly replaced. Replace only with the
same or equivalent type.
-The battery cannot be subjected to high or low extreme temperatures, low air
pressure at high altitude during use, storage or transportation.
- Replacement of a battery with an incorrect type can result in an explosion
or the leakage of ammable liquid or gas.
-Disposal of a battery into fire or a hot oven, or mechanically crushing or cutting
of a battery, can result in an explosion.
- Leaving a battery in an extremely high temperature surrounding environment
can result in an explosion or the leakage of flammable liquid or gas.
-A battery subjected to extremely low air pressure that may result in an
explosion or the leakage of flammable liquid or gas.
-An appliance is only suitable for mounting at a height of less than 2m.

GETTING STARTED
1. Remove the battery cover.
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 cover.
5. After inserting batteries, the transmission status LED will light up for 1 sec.
Note:
- Ensure to assign different channels of different sensors, in case you need
to pair more than one sensor.
- 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 upssuccessfully, 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 flash.
TEMPERATURE DISPLAY
On the display of the console which the soil sensor is linked to, a temperature
reading will be displayed.
SOIL MOISTURE DISPLAY
Soil moisture can be clarified into 5 different levels: Very Dry, Dry, Moist,
Wet and Very Wet.
To determine the moisture of soil, the sensor calibratesthe moisture into
16 points, and correlates them into percentage value:
Points Percentage Level
1 0%
Very Dry
27%
3 13%
420%
527%
6 33%
Dry
7 40%
8 47%
9 53%
10 60%
Moist11 67%
12 73%
13 80% Wet
14 87%
15 93% Very Wet
16 99%
Note:
The measurement accuracy of the sensor can be affected by the soil
condition. For example, the loose soil may get a lower moisture level
comparedwith the dense soil.

SENSOR PLACEMENT
Select the suitable installation site that insertsthe sensor probes into the
soil around 100mm (4 inch) and the sensor should be placedwithin 30
meters of the display console to get the best transmission performance.
Note:
The signal transmission range of the sensor will be gradually reduced as the
sensor is inserted deeper into the soil. To achieve the best transmission
range, install the sensor on the same plain of view as the display console.
RESET THE SENSOR
In case of mal-function, press the [ RESET ] button to reset the sensor.
