Product description: mmWave Human Detection Sensor Kit - human presence sensor - 24 GHz - Xiao ESP32-C3 - Seeedstudio 110061541
mmWave Human Detection Sensor Kit is a complete set that allows you to precisely detect the presence of people using mmWave technology. Equipped with the efficient Seeed Xiao ESP32-C3 chip, it offers the ability to connect to a WiFi and Bluetooth network, while supporting communication at a distance of over 100 m using a U.FL antenna. Thanks to the possibility of replacing mmWave sensors with others from the Seeed series and two Grove interfaces, this set is versatile in use. Configuration using Home Assistant using the No-Code method takes just 1-2 minutes, and software updates are available wirelessly via OTA (Over-The-Air). The main sensor in the kit is the mmWave Human Static Presence Module Lite , which detects motion, direction, speed and distance . Applications include home automation, building security, health monitoring and elder care.
The manufacturer has prepared a detailed user guide that makes using the module much easier. Check!

mmWave sensor operation
The mmWave radar sensor is an advanced device that uses millimeter wave radar technology to non-contact detect objects and determine their distance, speed and inclination angles. It works by sending and receiving signals with wavelengths ranging from 24 GHz to 300 GHz , which is called the millimeter spectrum. This sensor is based on Doppler radar technology, which allows it to operate regardless of environmental conditions such as temperature, humidity or noise. This is an ideal solution for a variety of applications, such as Smart Home applications, smart hotel systems or alarm systems.
