This Capacitive Soil Moisture Sensor measures soil moisture levels by capacitive sensing, rather than resistive sensing like other types of moisture sensor. Capacitive Soil moisture sensor is made of a corrosion-resistant material giving it long service life. Insert capacitive soil moisture sensor into the soil and impress your friends with the real-time soil moisture data!. The product includes an on-board voltage regulator which gives it an operating voltage range of 3.3 ~ 5.5V. It is compatible with low-voltage MCUs (both 3.3V and 5V logic). To make it compatible with a Raspberry Pi, an ADC converter is required.

Features Of Capacitive Soil Moisture Sensor:

  1. Operating Voltage: 3.3 ~ 5.5 VDC
  2. Output Voltage: 0 ~ 3.0VDC
  3. Interface: PH2.0-3P
  4. Dimension: 98mm * 23mm (3.86in x 0.905in)
  5. Supports Gravity 3-Pin interface
  6. Analog output

Applications:

  1. Garden plants
  2. Moisture detection
  3. Intelligent agriculture
