Overview
TS201 is a cost-effective LoRaWAN® temperature sensor from Milesight, designed for pharmaceutical and food cold-chain storage and related applications. It supports EN12830 compliance and HACCP requirements, provides local data storage to avoid data loss during connectivity interruptions, and features IP67-rated housing for rugged deployment.

Key Features

• Wide temperature monitoring range: -40 °C to 125 °C
• EN12830 certified to meet food and pharmaceutical regulatory requirements
• HACCP support via continuous monitoring and auditable data records
• Local storage of up to 4000 records with automatic retransmission after connectivity recovery
• LoRaWAN® long-range, low-power wireless communication; also supports Milesight D2D
• Detachable sensing probe for independent calibration and easier maintenance
• Optional glass-bead thermal buffer bottle to simulate product temperature and reduce false readings
• IP67 waterproof housing suitable for diverse environments
• Supports FUOTA (Firmware Update Over The Air) for remote firmware management

Compliance & Certification
EN12830 certified; CE and FCC approvals; RoHS compliant. The device is suitable for regulated pharmaceutical storage, cold-chain transport monitoring, food processing, and related applications where traceable temperature data is required.

Data Reliability & Management
TS201 stores up to 4000 entries locally to prevent data loss during network outages. Buffered data is retransmitted automatically once connectivity is restored. Real-time alerts (for example abrupt temperature changes or door-open events) notify users promptly, enabling corrective action and preserving product integrity.

Connectivity & Power
Utilizes LoRaWAN® (OTAA/ABP Class A) for long-range, low-power transmissions. Configurable via mobile app (NFC) or downlink. Powered by a single replaceable 2700 mAh ER14505 Li-SOCl2 battery, providing multi-year lifetime depending on network settings and region.

Typical Applications

• Pharmaceutical storage (vaccine refrigerators, medical freezers, drug cabinets)
• Cold chain transport and logistics
• Food processing and refrigerated storage
• Dairy/milk vat monitoring and other agricultural cold-chain cases

Advanced Usage Notes

• Detachable probe includes identification number to distinguish calibrated probes and help trace calibration status.
• Recommended to place the device module outside refrigerators while the probe measures internal conditions (minimize false readings and support wireless transmission).
• Optional mounting methods: wall screw, cable-tie, or magnetic (magnetic nut accessory available).
