DC 12V soil moisture sensor relay control module Automatic watering of the humidity starting switch
Description
1. This is a simple moisture sensor that can be used to detect soil moisture.
When the soil is short of water, the relay is disconnected, and the relay is sucked.
Use this sensor to create an automatic watering device that allows plants in your garden to be left unmanaged.
2. Sensitivity is adjustable (blue digital potentiometer adjustment in the figure)
3. Working voltage 12V
4. Relay output, control is more convenient.
5. With fixing bolt holes for easy installation
6. Small board PCB size: 3cm * 1.6cm
7. Power indicator (red) and relay suction and indicator (green)
8. Comparator uses LM393 chip, stable operation
Small board interface description (2-wire system)
VCC external 5V
GND external GND
Instructions for use
1. The soil moisture module is most sensitive to environmental humidity and is generally used to detect soil moisture.
2. When the soil moisture reaches the set threshold, the state of the relay is in the off state, and the output shows: normal open and public disconnect, normally closed and public conduction; when the soil moisture exceeds the set threshold, The state of the relay is in the suction state, and the output is represented as: normally open and common conduction, normally closed and public disconnected, and the user can embed it into his own system according.
The wiring parameters of the relay are:
AC voltage maximum 250V
AC current maximum 10A
DC voltage maximum 30V
DC current maximum 10A
Package Includes
1 x Module
1 x Sensor
2 x Cables
