NB Wireless Temperature Transmitter

Deep Coverage · Ultra-Low Power Consumption —— The Ultimate Solution for IoT Temperature Monitoring

YUNYI NB Wireless Temperature Transmitter is an intelligent temperature monitoring device based on NB-IoT (Narrowband Internet of Things) communication technology. It employs a high-precision temperature sensor to collect temperature data, which is then directly uploaded to the cloud platform via the carrier’s NB-IoT network, ensuring long-term stable operation under wide-area deep coverage. Featuring an IP68 protection rating and an extended battery life of 5-10 years, the device is specifically designed for temperature monitoring in industrial environments lacking mains power supply, characterized by dispersed locations and harsh conditions. It represents the optimal choice for building large-scale IoT temperature monitoring systems.
