LABX7 T330 NB-IoT – A versatile temperature and humidity monitor and recorder

LabX7 now integrates temperature sensors with NB-IoT in a beautiful and compact design. Now be connected with your information wherever you desire. NB-IoT temperature sensors transmit data wirelessly to the T330 using the backbone network and Narrowband-IoT communication technology. That means you do not need any additional devices to send measurements from the sensor. The T330 enables, among others measurements recording, notifications about exceeding safe thresholds and generates automatic reports. The devices are powered by 2000mAH batteries that ensure their maintenance-free operation for a period of at maximum two years. The sensor logs 65,000 temperature measurements in its memory.

The T330 is aesthetically pleasing, rugged and compact. The device has low power consumption, strong signal penetration, long communication distance, strong anti-interference ability, and convenient network performance. The temperature and humidity sensor is imported from abroad, and its surface is overmolded, which can reduce the sensor’s influence by external factors such as aging, vibration and volatile chemical gases, ensuring its stability – multiple EMC detection and industrial grade component selection.
