Soil Moisture Sensor Module With Corrosion Resistant Probe

• RESISTIVE SENSOR - 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.
• 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.
• ANALOG VALUE OUTPUT - The AO port on the soil humidity sensor outputs 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 indicator make you know the working status of the board at a glance at any time.
• CORROSION-RESISTANT ALLOY PROBE - A waterproof sensor probe with high corrosion resistance ensures a long lifetime at least 6 months in the soil.
