I Built a DIY ESP32 Millimeter-Wave Radar Sensor (for cheap!)

Video Description

#homelab #diy #homeassistant 🚀 Build Your Own Presence Sensor with ESP32 and Home Assistant We are diving into the wonderful world of ESP32 by creating our very own presence or proximity sensor. We will be using the tiny ESP32 C Super Mini and the LD2410 a Human Presence Radar Sensor Module. I will walk you through wiring it up, deploying it, uploading code to run your mmWave sensor, setting it up in Home Assistant, writing some automations for it in Home Assistant, soilder it all together, and then finely print a 3-D case for our presence sensor. 🖥️ Products and Links Project Materials - https://amzn.to/3EfaFEa Installing Home Assistant - https://www.home-assistant.io/installation/ Installing ESPHome on Home Assistant - https://esphome.io/guides/getting_started_hassio The 3-D Case - I recomposed this to add front holes and I switched to a different case as the intial one was a little tight for this project. This case gives you more ventilation, better exit for radar, and more space to shove it all in there. https://makerworld.com/en/models/1302910-esp32-c3-super-mini-ld2410c-case-front-holes#profileId-1335617 The Code - (be sure to add in your own wifi creditials if needed and add in the output_power wifi: ssid: !secret wifi_ssid password: !secret wifi_password output_power: 8.5dB https://pastebin.com/fK07Jpyu The 3-D Print 💡One of the great things about Home Assistant is they teamed with ESPhome in order to provide an easy way to onboard your custom sensors. By using ESPhome builder, home assistan add on, we can quickly deploy our sensors on our networks and easily upload code. You can even upload firmware and code over the air via wifi once you have them deployed. 🗒️Chapters 00:00 - What are we building? 01:40 - ESP32 C3 Pinout 03:20 - Wiring it all up 04:35 - Do you have Home Assistant? 05:33 - Using ESPHome Builder to Deploy 09:00 - Setting it up in Home Assistant 10:40 - Making some Home Automatoins 13:18 - Does it work? 13:45 - 3-D Printed Case 14:48 - Word of caution 16:00 - Soildering it 16:42 - Wrapping it all up 🔋Once we get our ESP32 Proximidy and Presence Sensor running inside of Home Assistant, the fun begins by using the LD2410 outputs to run some automations. I will walk you through a lighting scenerio for home automation needs where I replace my PIR sensors with homemade ESP32 sensor. This way I can better tell if someone is in the room or is not in the room. Thus giving me much better way to control automating my lighting. 📽️ My Other Home Lab Videos Discover my Top Home Lab Applications - https://youtu.be/yS72gNkpqok Learning Docker for Home Labs - https://youtu.be/RNlS4y-wfZs Virtual Machines for Homelabs - https://youtu.be/WjoiQgrFWXY How to Start a Home Lab - https://youtu.be/RqZSwEDXg_A Building Your Own Home Lab - https://youtu.be/y6ECUcVGg8o BUILD Your Own Cloud Storage - https://youtu.be/4hNcpdWEghQ I Chose UNRAID Over TrueNas - https://youtu.be/6V1qdiDoIL4 Discover my Top Home Lab Applications - https://youtu.be/yS72gNkpqok Basics of Home labs - https://youtu.be/y6ECUcVGg8o Raspberry Pi NVME Under Hat - https://youtu.be/jQRmBGEBkbg Raspberry Pi POE Hat - https://youtu.be/4mvGzSBd9Lg After this we have some fun, I show you my horrible soldering skills and I print out a 3-D case for the ESP32. 🚨 Be sure to like, comment, and subscribe for more tech related videos.
