NB-IoT People Counter (Black)

introduction

The NB-IoT People Counter is a battery powered sensor for counting people crossing a horizontal line. The counter consists of two parts, an infrared (IR) transmitter part and an infrared receiver part, which always work together.
The IR transmitter the infrared signal.
The IR receiver is the main part and holds the intelligence and communication with the outside world.

Principle of work
The IR transmitter device points the IR beam horizontal towards the IR receiver part at a recommended height. When this beam is interrupted, the algorithm in the IR receiver part determines if this was a person and determines the direction A or B.

Communication
The created data is communicated from the internal algorithm microprocessor to the internal gateway microprocessor. The internal gateway processor communicates this information to the internal module which takes care of the communication with the NB-IoT network. network.
Settings for the NB-IoT interface are done via NFC memory
