Temperature and Humidity Transmitter Temperature Sensor
The Flex2 series comprises versatile weatherproof LoRaWAN transmitters with multiple input options for industrial measurement and monitoring needs. The LoRaWAN radio provides extensive outdoor coverage and connects to standard LoRaWAN systems.
In comparison, the Flex2-T-RH LWEU/LWNA measures ambient temperature and relative humidity using a polymer sensor in the protruding black component. The device is composed of a measuring part and a radio part.
Key benefits include:
- High measurement accuracy and reliability
- Weatherproof
- The LoRaWAN radio offers a long range, especially outdoors, and connectivity to all standard LoRaWAN systems
- Ideal for industrial use

What is a Temperature and Humidity Transmitter?
A temperature and humidity transmitter is a device that measures and transmits data regarding temperature and humidity levels in a given environment. It typically utilises sensors to capture these measurements and transmits the data wirelessly to a monitoring system, allowing for real-time monitoring and control of environmental conditions.
