About this item
- 【Soil Moisture Sensor】: The corrosion resistance probe uses analog resistance to test soil moisture content. It can be used in the automatic watering system, garden, greenhouse, etc.
- 【Easy to Use】: This soil moisture detector produces a low signal on the DO port when the detected humidity exceeds the set threshold. It is compatible with Arduino and Raspberry Pi for easy integration.
- 【Adjustable Threshold】: Rotate the blue potentiometer to adjust the detection threshold. Power and signal indicators on the board provide real-time status updates.
- 【Analog Value Output】: The soil humidity sensor’s AO port provides an analog voltage value that can be obtained in real-time through the AD port of your microcontroller.
- 【Note】: “+” connects power positive; “-” goes to negative. Don’t connect reversely or the chip will be burnt out. There is a LED power indicator at the P mark on the board. It will be light if the module operates normally.
