Qwiic Human Presence Sensor (AK9753) Hookup Guide
Introduction
The AK9753 Human Presence sensor is a Qwiic enabled, 4-channel Nondispersive Infrared Sensor (NDIR). Each channel has a different field of view,
so not only can the AK9753 detect a human, but it can also tell which direction the person is moving.
This hookup guide will show you how to get started taking basic reading from the sensor. We will cover both a serial output of readings as well as nice
graph of the derivative of our readings from a single channel.
Required Materials
To get started, you’ll need a microcontroller to, well, control everything.
