Product Description

The Milesight TS30x LoRaWAN® Temperature Sensor series, consisting of the TS301 and TS302 models, is a sophisticated solution designed for accurate temperature monitoring in various environments. These sensors are particularly suitable for industries such as food production, pharmaceutical storage, and cold chain management, where precise temperature control is crucial.

The TS301 model is a single-channel version that supports the connection of a PT100 temperature probe or a door magnetic sensor. This model caters to standard temperature monitoring requirements. On the other hand, the TS302 is a dual-channel version that allows for the simultaneous connection of a PT100 temperature probe and a door magnetic sensor, or two PT100 temperature probes for more specific applications.
