Soil temperature monitoring for agriculture – COMETEO Radiation Shield with IoT Sigfox wireless sensor

Complete solution for remote wireless monitoring of soil and ambient temperature.

Autonomous battery powered IoT Sigfox sensor measures and records temperature of soil with stick-in probe and ambient temperature with probe placed inside of COMETEO.

The shield minimizes radiation reaching the sensor, minimizes radiation absorbed by the shield and maximizes ambient air flow around the sensor. The enlarged 200mm diameter of 13 plates is designed to provide full protection of measuring device. Cylindrical space with 110mm diameter and 185mm height is available inside of plates for the installation of measuring device with minimized solar radiation.
