4G Temperature Sensor with Alarm & Datalog – Waterproof, Long Battery Life

The NB-IoT Temperature Sensor is a robust and accurate solution for real-time environmental monitoring in agriculture, logistics, industrial operations, and smart infrastructure projects.

Equipped with a high-accuracy DS18B20 probe, it measures temperatures from -55°C to +125°C and transmits data to IoT platforms using low-power NB-IoT connectivity. Whether you’re tracking greenhouse climate, cold chain conditions, or outdoor weather trends, this sensor ensures reliable, long-range communication.

Its temperature alarm feature lets users set upper and lower thresholds for immediate alerts, while the datalogging function ensures no data is lost—even during network outages. With Bluetooth setup and OTA firmware updates, this device is easy to configure and maintain in the field.

Housed in a rugged IP66-rated enclosure and powered by an 8500mAh Li-SOCI₂ battery, the sensor is built for multi-year, maintenance-free use in harsh environments.
