    NB-IoT DC500 People Counter Sensor

    DC500 is a People Counter, which can be used to count the number of people entering and leaving each place; when the number of people exceeds the limit, it will immediately pass the information to the cloud server through the built-in NB-IoT (narrowband Internet of Things) module. It can be used for people statistics, over limit alarm and other functions. Users can observe status information remotely. The device uses a built-in battery to transmit data through the NB-IoT method, with high real-time performance and low power consumption.
