Overview
The TS601 is a compact LTE Cat.1 temperature and humidity sensor designed for reliable cold-chain monitoring during storage and transportation of food and pharmaceuticals. Built-in MEMS sensing and a status LED make it a straightforward all-in-one cellular logger.
An integrated temperature and humidity sensor covers −35 °C to +70 °C with typical ± 0.2 °C accuracy from 0 °C to 65 °C, while a status LED indicates device state and threshold alarms at a glance.
A light sensor detects cargo-box opening, a 3-axis accelerometer flags tilt and abnormal motion, and smart reporting sends routine data on schedule while excursions trigger instant alerts.
LTE Cat.1 connectivity with TCP, UDP, MQTT, AWS or the Milesight Development Platform keeps remote assets visible, and base-station positioning reports longitude and latitude along the route.
IP67 waterproofing with a specialized battery compartment, food-grade ABS+PC housing and flexible mounting (cable tie, 3M tape, wall screws or optional magnet) suit harsh cold-chain environments without vehicle modification.
Two replaceable CR18505 batteries deliver up to 4.8 years of operation, with local storage of 5,000 entries, retransmission, flight mode and NFC configuration for low-maintenance deployment.

Applications
Refrigerated trucks, insulated boxes and warehouse zones are monitored continuously, with threshold alarms and door-open detection protecting perishable goods in transit.
Vaccines and temperature-sensitive medicines stay within spec across the supply chain, with cellular backhaul and positioning for audit trails and regulatory compliance.
Base-station positioning and LTE reporting give visibility into where cargo is and how it is being handled, with tilt alerts flagging potential damage during transport.
Scheduled flight mode disables cellular transmission during air segments, helping meet aviation safety requirements while preserving data integrity on the ground.
