Ensure precise temperature monitoring across critical environments with the Milesight TS302 Dual Channel Temperature Sensor. This advanced LoRaWAN® resistance temperature sensor features an integrated LCD display and dual probe connectivity, making it the ideal solution for industries where accurate, traceable temperature data is non-negotiable.
The TS301 serves as a precision single-point instrument for temperature monitoring, while the TS302 is a multi-purpose powerhouse, capturing both temperature and door status simultaneously.
Suitable applications include:
The TS302 stands out with its low-power LCD display, providing clear at-a-glance temperature readings without draining the battery. Powered by two replaceable 4000mAh Li-SOCl₂ batteries, the device offers an impressive battery life of 5 to 15 years depending on configuration. Its rugged IP65-rated enclosure, with a dust-protected USB port, makes it well suited to harsh environments such as freezer rooms, production floors, and outdoor cold chain applications. The compact ear-like bracket design also makes wall mounting quick and straightforward.
Recorded data is transmitted wirelessly over a LoRaWAN® network, offering long-range connectivity of up to 2km in urban areas and 15km in rural environments, while keeping power consumption to a minimum. Based on the standard LoRaWAN® protocol, the TS302 connects to a LoRaWAN® gateway and can be visualised through your preferred dashboard or via Milesight's IoT Cloud. The device can also be configured quickly in the field via NFC using the Milesight mobile app.
