4G Dual-Probe Temperature Sensor – Industrial-Grade, Long-Life Monitoring
High-accuracy NB-IoT temperature sensor with dual probes, designed for industrial, agricultural, and remote monitoring. Offers long battery life, waterproof housing, alarm notifications, and cloud integration for real-time data and alerts.
This industrial-grade NB-IoT temperature sensor uses two high-precision DS18B20 probes to measure temperatures from –55°C to +125°C with an accuracy of ±0.5°C (max ±2.0°C). Its IP66 waterproof enclosure and robust design make it suitable for outdoor and harsh environment applications.
The device supports configurable temperature alarms for instant notifications and includes a datalogging feature to store readings when network connectivity is unavailable, automatically uploading stored data once the network is restored.
Multiple uplink protocols are supported, including MQTT, MQTTs, TCP, and UDP, enabling integration with a wide range of IoT platforms. Bluetooth Low Energy (BLE) setup and OTA firmware updates simplify deployment and maintenance.
Powered by an 8500mAh Li-SOCl₂ battery, the unit offers multi-year operation depending on reporting intervals and network conditions. An optional built-in SIM version is available for plug-and-play setup.
