ESP-Presence

ESP32-C6 SuperMini-based presence detection system with mmWave radar sensors and custom 3D-printed cases.

Overview

This project combines:

• ESP32-C6 SuperMini microcontroller
• LD2410C or SEN0610 (C4001) mmWave presence sensors
• 3D-printable cases designed in build123d/CadQuery
• ESPHome configurations for Home Assistant integration

Components

ESPHome Configurations

• esp32c6-ld2410c.yaml - Configuration for LD2410C sensor
• esp32c6-sen0610.yaml - Configuration for SEN0610 (C4001) sensor

3D Cases

Cases are modeled using build123d and CadQuery frameworks:

• LD2410C case: ld2410c/ - Compact enclosure for ESP32-C6 + LD2410C
• SEN0610 case: sen0610/ - Enclosure for ESP32-C6 + SEN0610 sensor
  • STL files: enclosure_base.stl, enclosure_lid.stl, corner_holder.stl
  • Assembly preview:

Development Setup

Prerequisites

• uv (Python package manager)

Install ESPHome

cp secrets.yaml.example secrets.yaml  # fill in your WiFi credentials
uv sync                                # installs ESPHome + dependencies

Usage

make compile-ld2410c   # compile LD2410C config
make compile-sen0610   # compile SEN0610 config
make compile-all       # compile both

make run-ld2410c       # compile + flash LD2410C (ESP32 must be connected via USB)
make run-sen0610       # compile + flash SEN0610

make logs-ld2410c      # stream device logs
make logs-sen0610

make clean             # remove .esphome/ build cache (~2 GB)

The first compile downloads the ESP-IDF toolchain (~2 GB).

3D Cases

Each case subdirectory (ld2410c/, sen0610/) is an independent uv project for build123d/CadQuery:

cd sen0610 && uv sync  # install case design dependencies separately

Requirements

• Python 3.13+
• uv
