Wireless Temp/HR Sensor for greenhouses


Convection Radiation Shield in combination with temperature & relative humidity sensor provides precise air temperature measurements for the greenhouse environment. Heat from the sun is used for heating the air in the pipe for vertical air flow which helps to have accurate temperature readings not affected by the solar radiation. The solution is wireless and battery powered, no external energy sources or additional equipment needed.

    Sensors are compatible only with Aranet base stations
    Measures: temperature (-40°C to 60°C)
    Measures: Relative humidity (0% to 100%)
    Line-of-Sight range: up to 3 km/ 1.9mi

* For best accuracy, recommended operating range is 20% to 80% RH (non-condensing) and 5°C to 60°C (41°F to 140°F).
Prolonged operation beyond these ranges may result in a shift of sensor reading, with slow recovery time.
