MS20 measures soil moisture content and temperature. It sealed with resin packaged plastic body with sensing rods which can be insert directly into the soil with long time stability. The soil moisture output signal can be RS485, Analog Voltage or Analog Current. It can also be calibrated for specific soils. The sensor is applicable for science research, irrigation, greenhouse, smart agriculture etc.
