Original spot soil moisture meter detection module robot intelligent car soil moisture sensor
Product Descriptions：
1. We use high-quality soil sensors produced by our company for soil moisture detection. The surface is treated with nickel plating, which widens the sensing area and improves conductivity, preventing rusting when in contact with soil and extending its service life;
2. The product can control the soil moisture in a wide range by adjusting the corresponding threshold through a potentiometer. When the humidity is below the set value, DO outputs a high level, and when it is above the set value, DO outputs a low level;
3. The comparator adopts LM393 chip, which works stably
4. Operating voltage: 3.3V-5V
5. Equipped with fixed bolt holes for easy installation
6. PCB size: 3.2cm * 1.4m
Wiring instructions (4-wire system)
1 VCC external 3.3V-5V
2 GND external GND
3 DO small board digital output interface (0 and 1)
4 AO small board voltage analog output
Module usage instructions:
1. The sensor is suitable for detecting soil moisture;
The blue potentiometer in the module is used to adjust the threshold of soil moisture. Clockwise adjustment will control a higher humidity, while counterclockwise adjustment will control a lower humidity;
3. The digital output D0 can be directly connected to a microcontroller to detect high and low levels, thereby detecting soil moisture;
The analog output AO of the 4 small boards can be connected to the AD module, and through AD conversion, more numerical values of soil moisture can be obtained;
