Flex2-nSens 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-nSens LWEU/LWNA measures temperature and humidity using a Novasina nSens probe. The probe needs to be ordered separately.
The device consists of three parts, a radio part, a measuring part, and a sensor.
