SECURUS/Hardware/Temperature and humidity sensor

Temperature and humidity sensors

A climate sensor measures temperature and relative humidity at its installation point. Range, accuracy and housing are selected for indoor climate, storage conditions and humidity monitoring. Readings are sent to SECURUS over LoRaWAN.

Technical data according to the manufacturer's datasheet, battery life under the stated conditions. All devices shown transmit via LoRaWAN. In addition to these examples, we also use LoRaWAN devices from other manufacturers depending on requirements.

Choose where to measure temperature and humidity

Place the sensor where the reading is needed. Direct sunlight, radiators and air outlets can influence measurements. Mold prevention benefits from trends; cold room equipment needs the appropriate temperature range.

FAQ

Sensor selection questions

Can this sensor measure moisture inside a wall?

No. It measures air humidity at its location. Moisture inside building materials requires another method.
