parator uses the LM393 chip, which works stably.
Equipped with fixing bolt holes for easy installation.
The product can control the soil humidity in a wide range, and adjust the corresponding threshold through the potentiometer. When the humidity is lower than the set value, DO outputs high level, and when the humidity is higher than the set value, DO outputs low level.
Working Voltage: 3.3V-5V
PCB Board Size: 31× 14 mm
Kit Weight: 7 g
Application:
Adjusting the soil moisture control threshold through the potentiometer can automatically control vegetable gardens, automatic watering of gardens, soil moisture control of home flower pots, various electronic games, electronic building blocks, arduino designs, etc.
Interface Description (4-wire):
VCC: 3.3V-5V
GND: GND
DO: Digital output interface (0 and 1)
AO: Analog output interface
Module instruction:
1. The sensor is suitable for soil moisture detection;
2. The blue potentiometer in the module is used to adjust the threshold of soil humidity. It is adjusted clockwise, and the controlled humidity will be larger, and counterclockwise will be smaller;
3. The digital output D0 can be directly connected with the single-chip microcomputer, and the high and low level can be detected by the single-chip microcomputer, thereby detecting the soil moisture.
Packing List:
5 x Soil moisture detector module
5 x Probe
10 x Jumper cables
