DRAGINO NB-IoT Waterproof Outdoor Temperature Sensor
DRAGINO NB-IoT Waterproof Outdoor Temperature Sensor are NB-IoT temperature sensors designed for remote temperature monitoring applications. Using a Dallas DS18B20 temperature probe, the sensor measures from -55°C to 125°C with an accuracy of ±0.5°C, with a maximum stated error of ±2.0°C. Temperature readings can be transmitted to an IoT platform via NB-IoT using MQTT, MQTTs, UDP or TCP. The IP66 enclosure, 8500mAh Li-SOCI2 battery, temperature alarms and Bluetooth configuration support make the D20-NB suitable for long-term monitoring installations.
The DRAGINO NB-IoT Waterproof Outdoor Temperature Sensor (D20-NB and D20S-NB) are battery-powered NB-IoT temperature sensors designed to collect temperature data and transmit it to an IoT platform. They are suited to monitoring applications where temperature information needs to be collected remotely without a conventional wired network connection.
The sensor uses a Dallas DS18B20 temperature probe with a stated measurement range of -55°C to 125°C and an accuracy of ±0.5°C, with a maximum stated error of ±2.0°C. The D20-NB and D20S-NB also provide configurable temperature alarms for applications where temperature conditions need to be monitored against defined limits.
How it works
- The DS18B20 probe measures the surrounding temperature.
- The D20-NB/D20S-NB processes the temperature reading and sends the data through an NB-IoT network.
- Data can be uploaded to compatible IoT servers using MQTT, MQTTs, UDP or TCP.
- The D20-NB includes a datalog function that can retain readings when NB-IoT connectivity is unavailable and upload the stored data when the connection is restored.
- Bluetooth can be used for remote configuration and firmware updates.
- Temperature alarm settings can be configured to provide notification when defined temperature conditions occur.
Why choose this product?
The DRAGINO NB-IoT Waterproof Outdoor Temperature Sensor is a practical option where temperature data needs to be collected remotely over an NB-IoT network. Its combination of an external temperature probe, low-power operation, IP66 enclosure and battery supply allows it to be installed in locations where regular wired monitoring may not be practical.
The D20-NB also provides data logging for periods without NB-IoT connectivity, helping prevent temperature readings from being lost during network interruptions.
