5 Sets Soil Moisture Sensor, Resistive Soil Moisture Meter, Soil Hygrometer Sensor Test Kit with Corrosion Resistant Probe Digital Analog Signal Output for Garden Automatic Watering System
【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. Compatible with raspberry pi.
【Corrosion Resistant Probe】The waterproof sensor probe with high corrosion resistance ensures a long lifetime in the soil.
【Digital Analog Signal Output】The AO port on the soil humidity sensor outputs an analog value(voltage), and you can acquire the real-time data via the AD port of your single-chip microcomputer(MCU).
【Adjustable Threshold】Clockwise/counter-clockwise rotate the blue potentiometer to increase/reduce the detection threshold. On-board power and signal indicators make you know the working status of the board at a glance at any time.
【Easy to Use】It can automatically watering your plants and flowers according to monitor the soil moisture.This soil moisture detector outputs a low level from the DO port when the detecting humidity reaches the threshold value.
