The Milesight TS301 is a LoRaWAN temperature sensor with a local LCD, built for cold rooms, freezers, pharmacy fridges and food production. It reads one PT100 probe through a sealed M12 connector, so probes can be swapped or sent for calibration without opening the unit.
Why pick it
- 1 x M12 input: PT100 probe or magnetic contact switch. A door contact lets you match temperature excursions to door openings.
- Stores 10,000 readings and exports them as CSV or PDF over USB-C, for audit records.
- Milesight lists EN12830, HACCP and 21 CFR Part 11 support.
Probes are ordered separately: the B-class PT100 probe (SP11-B05-125-200), the A-class PT100 probe (SP11-A05-500-150), the A-class food-grade needle probe (SP11-AF10-125-150) and the magnetic contact switch (SS21-PN03-150) for door monitoring.
Works with any standard LoRaWAN gateway and network server, such as the Milesight UG65 indoors or the UG67 outdoors, with alerts and dashboards on IoT Factory.
