TS301/TS302 – PT100 LoRaWAN Temperature Sensors with LCD Display – Milesight
General Description
Milesight 's TS301 and TS302 are LoRaWAN® temperature sensors compatible with PT100 probes. The TS301 model allows you to connect a PT100 probe or a magnetic sensor, while the TS302 accepts two inputs (two PT100s or one PT100 + one magnetic sensor). Featuring a segmented LCD display, a data logger (10,000 measurements), and a configuration interface via NFC, USB-C, or downlink, these sensors are ideal for cold chain, food, and pharmaceutical industries. Their IP65 housing guarantees use in demanding environments.
