Flex2-T-RH LWEU/LWNA temperature and humidity transmitter
The Flex2 series is a multipurpose weatherproof LoRaWAN transmitter series with several input options for various needs of industrial measurement and monitoring. The LoRaWAN radio offers a long range, especially outdoors, and connectivity to all standard LoRaWAN systems. Compare the Flex devices.
Flex2-T-RH LWEU/LWNA measures the ambient temperature and relative humidity with a polymer sensor in the protruding black part.
The device consists of two parts, a measuring part and a radio part.
