Soil Moisture Sensor Module Soil Moisture Meter Module Components

Through the potentiometer adjusting soil moisture threshold control, can automatically in garden, garden automatic watering and family flowerpot soil humidity control and a variety of electronic than
Race, electronic building blocks, Arduino design, etc..
Product introduction:
1 the use of the company's production of high quality soil sensor to do the detection of soil moisture, the surface of nickel plating treatment, there is a widening of the area, can improve the guide
Electrical properties, prevent contact with the soil easy to rust problem, extend the service life;
2. The product can be a wide range of control soil humidity and control the corresponding threshold value by adjusting the potentiometer and the humidity is lower than set value, dissolved oxygen (do) and outputs a high level, higher than the
Set value when the DO output is low;
3 comparator uses LM393 chip, work stability
4 working voltage 3.3V-5V
5 with fixed bolt holes, easy to install
6.PCB size: 3.2cm * 1.4m
Wiring instructions (3 wire)
1 VCC external 3.3V-5V
