LSN50v2-S31B - LoRaWAN Temperature and Humidity Sensor

The Dragino LSN50v2-S31B LoRaWAN Temperature and Humidity IoT Sensor is fitted with a quality Sensorion SHT31 probe in an anti-condensation enclosure that is attached to the main body. It has been factory calibrated and temperature compensated, so can precisely measure Temperature and Humidity both indoors or outdoors. It has a temperature range of -40 to 85C and a Humidity range of 0 to 99.9%. As an added bonus, the Vapor Pressure Deficit (VPD) and the Dew Point is also calculated and displayed when used with Telemetry2U.

Telemetry2U has a live demo of a Dragino LSN50V2-S31B running on our IoT Platform here.

The Dragino LSN50v2-S31B is a long range LoRaWAN node that provides spread spectrum communication and high interference immunity whilst minimising power consumption. Its IP68 waterproof design makes it suitable for outdoor use and its powered by a 8500mA Li/SOCl2 non-rechargeable battery. Due to its low power operation, users can expect years of operation with a moderate logging rate. 

The Sensirion SHT31 probe is factory calibrated with temperature compensation for precise measurement over the entire range.

It has a user propgrammable threshold so that you will be immediately informed if you sensor drifts past that threshold.  When used with Telemetry2U, you can receive these alerts via Email, SMS or via an interactive voice call, ensure you assets have the ultimate level of protection.

The Dragino LSN50v2-S31B can be configured with downlink commands or alternativly, you can configure your device with a FT232RL USB to TTL converter.


Please note that all LoRaWAN end-devices sensor's supplied by Telemetry2U will work with 3rd party network/application servers, like TTN, but if you would like to use your sensors on Telemetry2U’s advanced, plug-and-play IoT Platform, then you will need to purchase a license by selecting from the drop-down box. Products purchased with a license will be shipped with the latest firmware and configuration optimised for T2U, with no programming or set-up required.
