Pt100 temperature sensor TS301

semiconductormagnetic-mountwall-mount

Overview
The TS30x series is a high-accuracy LoRaWAN® temperature sensor with an LCD segment display. It supports detachable temperature and temperature-humidity probes (including PT100) and optional door magnetic sensors for refrigerated/freezer and pipe monitoring. Designed for food, pharmaceutical cold chain and industrial monitoring, the series provides local display, secured data export and long-term autonomous operation.

Key Features

• EN12830 certified for cold-chain traceability and HACCP support for food safety.
• Secure automated data export (encrypted PDF) and features to assist 21 CFR Part 11 compliance when integrated with suitable platforms.
• LCD segment display for at-a-glance readings with low-power design.
• Multiple probe support: detachable temperature / temperature-humidity probes including PT100 and DS18B20; optional door magnetic contact sensors.
• Local data logging: up to 10,000 historical measurements with retransmission to prevent data loss.
• Wireless: LoRaWAN® (OTAA/ABP) with Milesight D2D support for device-to-device control; Class A operation.
• Long battery life: 2 × ER18505 (4000 mAh) or USB Type-C power; typical multi-year operation depending on configuration.
• Rugged: IP65 ingress protection; USB Type-C port protected by dust caps.
• Easy deployment: one-tap NFC configuration via mobile app (Milesight ToolBox), wall-screw or optional magnetic mounting, and thermal buffer accessories.
• Remote maintenance: supports FUOTA (Firmware Update Over-the-Air).

Models and Usage

• TS301 — Single-channel: supports one temperature or temperature-humidity probe or one door magnetic sensor.
• TS302 — Dual-channel: supports two temperature/TH probes or one temperature/TH probe plus one door magnetic sensor (cannot support two door magnetic sensors simultaneously).

Applications

• Food cold chain monitoring: warehouses, refrigerators, freezers and kitchen units with continuous logging and instant alerts for excursions.
• Pharmaceutical and medical cold chain: vaccine refrigerators, pharma cold rooms with timestamped logs and audit-ready exports.
• Commercial buildings and industrial sites: water/energy monitoring, pipe monitoring, multi-site operational alerts and centralized cloud integration.

Accessories & Probe Flexibility
The TS30x series works with a wide range of detachable probes and accessories: food-grade PT100 probes, industrial PT100 probes, DS18B20 probes, glass-bead thermal buffer bottles for improved stability, magnetic mounting nuts, door magnetic sensors, and optional power adapters/converter kits. Detachable probes allow calibration and replacement.
