EQ-3 Temperature and humidity sensor

The compact sensor measures temperatures between minus 20 °C and plus 55 °C, as well as relative humidity from 0 to 99%. When used in conjunction with other Homematic IP devices, it offers numerous practical applications. For instance, the sensor can be utilized for ventilation or dehumidification controls, as a frost guard for heating sensitive greenhouse plants, and in many other scenarios. Additionally, the collected weather data is displayed and analyzed in the Homematic IP app. Power is supplied by two LR6 batteries, which can typically energize the sensor for five years. The necessary mounting materials are included.
