Soil Moisture, Temperature & Conductivity Sensor

Soil Moisture, Temperature & Conductivity Sensor



Order

Description

The 5TM is designed to measure the volumetric water content and temperature of soil and growing media. Using an oscillator running at 70 MHz, it measures the dielectric permittivity of soil to determine the volumetric water content. A thermistor in thermal contact with the sensor prongs provides the soil temperature.


Feature

  • Temperature Integrated with Soil Moisture
  • Engineered for Accuracy
  • Easy Installation
  • Plug and Read
