People Counting System built with Wio Terminal and Ultrasonic Sensor

With TinyML running right on the ATSAMD51 powered Wio Terminal, we can train a machine learning model on distance patterns to recognize when people are moving in or out of a room.

With some additional programming to keep count, and using the Wio Terminal's onboard WiFi & Bluetooth, we can easily build a cloud-connected application to monitor room occupancy remotely with IoT platforms like Azure IoT Central.
