The ANWETECH AT-H231 is a wall-mounted LoRaWAN sensor designed for remote temperature and relative humidity monitoring.
In addition to environmental sensing, the device integrates GNSS positioning and accelerometer-based motion detection. It supports GPS, BeiDou and GLONASS positioning and can transmit monitoring data through a LoRaWAN network.
The AT-H231 supports LoRaWAN 1.0.2 and operates as a Class A end device using OTAA network activation. Multiple LoRaWAN frequency bands are available to support deployment in different regions.
The device features an IP67 UV-resistant enclosure, magnetic activation and buzzer indication.

The AT-H231 communicates through a LoRaWAN network and is compatible with standard LoRaWAN gateways and third-party network servers.
Supported frequency bands include:
EU868, CN470, IN865, US915, AU915, AS923
The appropriate frequency version should be selected according to the LoRaWAN network frequency used in the deployment region.
The AT-H231 is designed for screw-fixed wall mounting.
For GNSS positioning, the GPS antenna should be installed outdoors in an unobstructed location to provide suitable satellite signal reception.
The main device body should be installed indoors according to the installation requirements described in the product documentation.
The AT-H231 is suitable for applications requiring:
