soil humidity module to the environmental humidity is the most sensitive, generally used to detect soil moisture. module in soil moisture can not reach the setting threshold, DO mouth output high level, when soil moisture more than setting threshold, module D0 output low level; small plate digital output D0 can be directly connected with the single chip microcomputer, through the single chip microcomputer to detect the high and low level, thus to detect soil moisture;

Product description

1.This is a simple moisture sensor can be used to test the moisture of soil, when the soil water shortage, module output a high level, and output low level. Use this sensor making one automatic watering the flowers device, make your garden plants need not to management.
2 sensitivity adjustable (shown in blue digital potentiometer control)
4 working voltage of 3.3 V - 5 V
5 module double output mode, digital output is simple, analog output more accurate.
6 has fixed bolt hole, convenient installation
7 small board PCB size: 3 cm * 1.6 cm
8 The power indicator light (red) and digital switch output light (green)
9 comparator the LM393 chip, work stability
 
Techinical
 
Two small plate interface specifications (4 wire)
1 VCC external 3.3 V - 5 V
2 GND external GND

Instructions
1 soil humidity module to the environmental humidity is the most sensitive, generally used to detect soil moisture.
2 module in soil moisture can not reach the setting threshold, DO mouth output high level, when soil moisture more than setting threshold, module D0 output low level;
3 small plate digital output D0 can be directly connected with the single chip microcomputer, through the single chip microcomputer to detect the high and low level, thus to detect soil moisture;
4 small plate digital output DO can directly drive the relay module, buzzer module, which can form a soil humidity alarm equipment;
5 small plate analog output AO and AD module can be linked together, through the AD conversion, can get soil moisture more accurate numerical;
