Milesight TS302-868M – LoRaWAN® Temperature Sensor with Dual Probe Support

The Milesight TS302-868M is a next-generation resistance temperature detector (RTD) that provides versatile and precise temperature monitoring. With support for two 3-wire PT100 sensors or a PT100 + magnetic switch sensor, it enables advanced monitoring configurations for applications like cold storage, food processing, and temperature-critical logistics.

An integrated LCD segment screen allows real-time temperature display on-site. The TS302 uses LoRaWAN® technology for long-range, low-power wireless communication and is compatible with Milesight IoT Cloud and standard LoRaWAN® gateways.

The device features extensive local data storage (10,000 readings) and supports CSV or PDF export via NFC or USB-C. Alarm functions for threshold exceedance and sudden temperature changes ensure responsive alerts.

Its IP65-rated enclosure, optional magnetic mounting, and robust battery system (2× 4000 mAh) guarantee reliable operation in tough conditions. Depending on sensor usage, battery life can reach up to over 5 years, or 10 years with only a magnetic sensor.

The TS302 is EN12830 certified for cold chain applications and supports HACCP-compliant data integrity, offering traceability and secure data logging per 21 CFR Part 11B.
