2 Sets Resistive Soil Moisture Sensor, Icstation Humidity Detector, with Corrosion Resistant Probe, Digital Analog Signal Output for Arduino Garden Automatic Watering System
- 【Soil Moisture Meter】The probe uses analog resistance to detect the moisture content of the soil. It is a good plant helper to make you know if your plants are thirsty and it can also be used in the automatic watering system, garden, greenhouse, etc..
- 【Easy to read】Digital value output,this soil moisture detector outputs a low level from the DO port when the detecting humidity reaches the threshold value. Good to work with Arduino/Raspberry Pi..
- 【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..
- 【Analog Value 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)..
- 【Corrosion Resistant Alloy Probe】A waterproof sensor probe with high corrosion resistance ensures a long lifetime of at least 6 months in the soil..
