The LoRaWAN Infrared People Counting Sensor delivers highly accurate real-time data on pedestrian traffic for smart management. This article will explain its key components, sensing technology, and LoRaWAN data transmission process.
Key Components of the Sensor
The sensor consists of two main units — the infrared transmitter and receiver. The transmitter emits modulated infrared beams in multiple directions. The receiver unit detects these signals on the opposite end to identify pedestrian movements.
Setup and Positioning
The transmitter and receiver units are installed facing each other at a height of 0.8m to 1.3m across doorways, corridors, gates, or other areas of interest. A distance of 2m to 10m can be covered based on the detection angle.
Precise alignment ensures the receiver obtains clear, unobstructed infrared beams from the transmitter for accurate counting. The compact form factor allows unobtrusive positioning.
Sensing and Counting Principle
Infrared Detection Technology
The infrared transmitter beams are arranged to create multiple sensing barriers. When people walk through, their bodies intersect these beams. The receiver detects these infrared interruptions to identify pedestrian movement.
By arranging transmitters and receivers on both sides, the sensor can identify directionality of movement, giving accurate counts in both ingress and egress directions.
Data Transmission via LoRaWAN
LoRaWAN Network Connectivity
Cloud Platform Integration
The data is seamlessly integrated with the management platform to generate usage reports, analytics and visualizations for convenient access from any device.
In summary, the LoRaWAN Infrared People Counting Sensor uses advanced infrared transmitters and receivers to reliably detect pedestrian movement. It transmits real-time data wirelessly over LoRaWAN to the cloud platform, providing convenient traffic analytics. The technology ensures highly accurate bi-directional counts for smart space management.
