Specificatii
Soil Humidity Relay Module Sensor Garden Moisture Detector LM393 Chip Indicator
This is a simple water sensor can be used to detect the moisture
of the soil, when the soil water deficit, the relay is switched
off, and vice versa relay. Use this sensor produced an automatic
watering device, so that the plants in your garden need not to
manage.
2 adjustable sensitivity (blue digital potentiometer
adjustment)
4 Operating voltage 3.3V-5V
5 relay output, more convenient to control.
6 with fixed bolt hole for easy installation
7 board PCB size: 3cm * 1.6cm
8 power indicator (red) and relay and indicator (green)
9 comparator LM393 chip, stable
Two small plates Interface Description (2-wire)
VCC external 3.3V-5V
2 GND external GND
Three use
1 soil moisture module is most sensitive to environmental humidity
is generally used to detect the moisture content of the soil.
2 module in the soil moisture of less than the set threshold value,
the status of the relays in a disconnected state, the output
performance: normally open and public open, normally closed, and
public conduction; exceeds the threshold value is set when the soil
moisture relay state absorption and status, the performance of the
output: normally open with the public on pass, normally closed and
public disconnect according to this principle embedded in the own
system. Relay wiring parameters: AC voltage 250V, AC current
maximum 10A maximum 30V DC voltage, DC current up to 10A
Fourth shipping list
1 as shown in a set of soil moisture detection module finished
board (including the detection plate and soil humidity probe)
2 20cm DuPont line 2 for easy wiring;
To extend the life of the probe tips: If the buyer needs to delay
the life of the soil probe, the entire probe with a soldering iron
plus solder, so that the surface of the probe through holes are
filled with solder, the life of the probe will be greatly enhanced
