Soil moisture sensor module 5V capacitive detection 12V sensor relay automatic watering DIY kit

Soil moisture detection module

1· Use the high-quality soil sensor produced by our company to test the soil moisture. The surface is treated with nickel plating, which has a widened sensing area, which can improve the electrical conductivity, prevent the rustiness of the soil and prolong the service life.
2. The product can control the humidity of the soil in a wide range, and control the corresponding threshold through the potentiometer. When the humidity is lower than the set value, the DO output is high, and when it is higher than the set value, the DO output is low.
3. The comparator adopts LM393 chip and works stably;
4, with a fixed bolt hole, convenient installation;
5, adjustable sensitivity (blue digital potentiometer adjustment);
6, power indicator (red) and digital switching output indicator (green);
7, module dual output mode, digital output is simple, analog output is more accurate.
8, working voltage 3.3V-5V9, PCB size :3.2CM* 1.4M
