About DIY-Sensors

Welcome to DIY-Sensors.com – the place where makers, tinkerers, and smart home enthusiasts come together to build practical, reliable, and privacy-friendly sensor solutions.

This site was created to help you get the most out of your ESP32 and ESP8266 boards. Whether you're just starting out or already building your own advanced automations, DIY-Sensors offers hands-on projects, wiring guides, tested Arduino code, and integration tips for Home Assistant.

Every tutorial is built around real-world use cases, from smart motion detectors and air quality sensors to efficient presence sensors and wireless communication setups. The goal is to not just show you what to build, but to help you understand how it works and why it matters.

What makes DIY-Sensors different?

• No cloud: All projects run locally and are designed to keep your data private.
• Efficient by design: Sensors send only what matters, reducing traffic and database size in Home Assistant.
• Open and reusable: Everything is shared—code, 3D files, diagrams—so you can build, customize, and improve it.

You’ll also find in-depth pages about the most commonly used components, complete with wiring examples, recommended settings, and code snippets.

Whether you're here to learn, build, or contribute—DIY-Sensors is your starting point for smarter, faster, and more transparent sensor development.
