MikroTik TG-LR82 - LoRaWAN temperature and humidity sensor (868 MHz / 2.4 GHz)

MikroTik TG-LR82 – Configurable LoRaWAN Sensor

MikroTik TG-LR82 is a configurable tag and environmental sensor designed for use in wireless networks for IoT devices. The device is designed to collect data, allowing for simultaneous monitoring of temperature, humidity levels, and motion detection using a built-in accelerometer. Thanks to the use of a highly accurate temperature sensor compliant with NIST standards, this device is ideal for monitoring supply chains and goods sensitive to thermal changes.

The device features built-in data processing – it can locally generate measurement averages and histograms before sending them. This solution drastically reduces the load on the wireless network while maintaining full information about environmental conditions. An additional advantage is the integrated reed switch, which, when a magnet is placed near it, allows for simple and effective monitoring of door, cabinet, or cover openings.

The device supports LoRaWAN protocol version 1.0.4 (for classes A and B). The sensor features dual-frequency support: the standard 868 MHz and the universal 2.4 GHz. The latter allows for trouble-free use worldwide without worrying about local radio restrictions (which is crucial, for example, in international maritime transport). All electronics are housed in a sealed, IP67-certified housing resistant to harsh conditions. A built-in, non-replaceable 1100 mAh battery guarantees long-term operation – up to five years with optimal reporting settings.

The module is optimized for seamless integration with the MikroTik LoRaWAN gateway ecosystem. Officially supported and compatible devices include:

• KNOT LR8G kit

• wAP LR8G kit

• wAP LR2 kit

The sensor also supports easy integration with analytical and monitoring platforms such as The Things Network (TTN) and Grafana (thanks to container support in RouterOS).
