Intended Use
The SMG9631 sensor detects soil volumetric water content (VWC)
through sensing the dielectric constant of the media using capacitance
domain technology. The sensor is built on PCB, it is reliable in almost
any soil. The system has a self learning process built to eliminate the
influences of different soil or media. Also on the remote sensor, it
measures outdoor temperature, which is received and displayed on by
the receiver for easy reading purpose. Since the temperature sensor is
located inside the moisture sensor housing, when exposing to direct
sun light, the outdoor temperature reading will be a few degrees higher
comparing to normal air temperature. So strongly recommending to put
the sensor in sun shine shaded locations
The remote sensor data is updated around every 90s. After watering
the soil, the sensor takes about 4 readings. If the 4 reading data is
consistent, new data will be updated accordingly. So there is a delay
between watering the soil and having the new data displayed. The
typical time needed before an update is about 4~5 minutes
It is ideal for use in your garden or plants pots in house. The
transparent plastic case is made from PC which is resist to environment
aging. It is suitable for indoor and /or outdoor use purpose.
Battery Safety
Correct polarity must be observed while inserting the batteries.
Batteries should be removed from the device if it is not used for a
long period of time to avoid damage through leaking. Leaking or
damaged batteries might cause acid burns when in contact with
skin, therefore use suitable protective gloves to handle corrupted
batteries.
Batteries must be kept out of reach of children. Do not leave the
battery lying around, as there is risk, that children or pets swallow
it.
Power Supply
-
Sensor: LR3, AAA alkaline batteries 2pcs
-
Receiver: LR6, AA alkaline batteries 2pcs
If the item is sold with battery included, there is an insulator under the
battery, remove it before use.
Quick Setup
Hint:Use good quality Alkaline batteries and avoid using rechargeable
batteries。
1.
Have the display unit and remote unpacked from the gift box.
2.
Place the batteries into the indoor temperature station first. All
LCD segment will be turned on for 4 seconds, then the Outdoor
Reception Signal Icon displayed, indicating that receiver is trying
to find the remote sensor. Please do not press any key, which will
interrupt the matching process between the sensor and receiver.
Then place the batteries into the remote sensor, and the indicator
LED will be lit for about 20s. After that, transmitter will send out
temperature reading and air sensor reading (which is the absolute
lowest possible reading) first. If the receiver decodes the sensor
data successfully, the sensor temperature and soil moisture
reading will be displayed. The outdoor temperature and soil
moisture data is toggled for display for 3 seconds. The matching
process will take 400s before automatic completion.
3.
If a key is pressed before the station receives the sensor data, the
receiver will terminate the matching process and it will take 10
minutes before the receiver re-synchronizes with the outdoor
sensor again. If a reset is needed for receiver or transmitter, pull
out the batteries and wait 10 seconds before re-insert the battery
to make a proper reset.
4.
After matching process is completed, then insert the sensor into
the location you want to monitor the soil moisture. The depth of
the sensor should be around 8 ~10cm below surface. make sure
the soil is tight around the sensor because it is most sensitive to
soil adjacent to the sensor. Stones or air pockets next to the
sensor will affect the accuracy of the readings. Because it is
sensitive to the dielectric permittivity, care should be taken not to
install sensor in or near metal. Pour water into the soil until the
surface glistens and no more water can permeate. The sensor
now will senses the maximum water content level, and after a few
minutes(about 4 minutes), the highest water level will be
displayed on the receiver LCD: 99%( please note that the “Wet
Soil” reading of 99% is not necessary an exact soil moisture
content level, it only means that this is the most wet conditions
you can have for this part of the soil). There is a self calibrating
process built inside the sensor and the time needed for finishing
the self calibrating process could be varied due to data stabilizing
reason. The longest time needed for this self calibrating is 20
minutes.
5.
Now it is ready for the sensor to monitor the soil moisture. When
water level drops, the wet soil data will drop accordingly. Please
note that the wet soil reading is not linear to the water content.
User should be able to tell by him/herself which reading is to be
used for watering/not watering condition.
6.
If you need to put the sensor into another location, in order to
eliminate the difference between the soil, take out the battery and
wait for 5s and then restart the above five steps again. Without
initiating the self-learning procedure, this could lead to permanent
reading error!!

Important: The sensor can be damaged if it is pushed directly into
hard native soil. Please do not use hammer or other blunt hard
instrument during the installation. Also as the soil surrounded to
