Description

MMW-1 Presence Sensor: Founders Edition (24GHz mmWave)

The MMW-1 is a custom-engineered, ultra-compact human presence sensor designed specifically for seamless, local-first integration with Home Assistant via ESPHome.

Unlike standard PIR motion sensors that leave you in the dark when you sit still, the MMW-1 uses advanced 24GHz mmWave micro-radar technology to accurately track true human presence—even if you are completely stationary, reading, or sleeping.

### Key Features:

- High-precision 24GHz radar module (LD2410C)

- Powered by a compact ESP32-C3 SuperMini

- 100% local control for maximum data privacy ("private-by-design")

- Clean, compact multi-layer PCB layout optimized for easy assembly

This project is fully open-source. Simply flash your ESP32-C3 using ESPHome, drop it into your local smart home network, and enjoy instantaneous, rock-solid automation tracking.
