LD2410C Human Presence Sensor

Learn to use the LD2410C Human Presence Sensor with an ESP32, Windows, and Bluetooth. Find those pesky humans, wherever they might be hiding!

The ability to sense human beings is instrumental in security, safety, and home automation applications. We have done it before using PIR sensors, but they trigger just as well on humans as they do on dogs and cats, and are prone to numerous false triggers.

Enter the Microwave Human Presence Detector. This class of sensor utilizes FMCW Radar at 25 GHz to detect humans, both moving and stationary, at distances of over 5 meters. And it won’t trigger when your cat walks into the room!

Despite their sophistication, these sensors are very easy to use.

Today, we are testing a very popular Human Presence Sensor, the LD2410 from Hi-Tech. This low-cost device is highly accurate and can be tuned to match the room's characteristics.

We will be using the sensor with a Windows GUI, a Bluetooth App, and with an ESP32. It can also work directly with ESPHome for users of Home Assistant.
