- A soil moisture sensor measures the water content in soil and is used in agriculture, gardening, and research to determine the moisture needs of the soil. These sensors typically use two probes to measure soil’s resistance, which changes with moisture.
- Operating Voltage: 3.3V to 5V DC
- Operating Current: 15mA
- Output Digital – 0V to 5V, Adjustable trigger level from preset
- Output Analog – 0V to 5V based on infrared radiation from fire flame falling on the sensor
- LEDs indicating output and power
