Soil Moisture Sensor for Garden Automatic Watering System (4 Sets)

About this item

• When the soil moisture detector senses the humidity level, it sends a low signal to the DO port. Works well with Arduino and Raspberry Pi.
• 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.
• Soil Moisture Sensor and Soil Detector Module Soil Moisture Test Soil Humidity Test Corrosion Resistance Probe for Arduino
• 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).
• 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.
