It should be a piece of cake if you program your Attiny85 chip (not Digispark) using your existing Arduino IDE with the help of one “USB tiny ISP (v2.0)” programmer. The software/Arduino sketch /* * ...

Some lights have motion sensors already built into them. For example, Ring has a great outdoor light with motion sensor that ties into the rest of its smart home ecosystem.

Choose a location. Y ou can install motion sensor lights anywhere, but if you want them to provide security and not simply illuminate your path in the dark, place them high enough to be able to ...

The microcontroller-based concept was chosen because I wanted to scale the sensor system later to suit other applications. Here is the diagram of my Arduino infrared close proximity sensor. As you can ...

When the sensor detects motion — i.e. someone passing in the hallway or someone opening the door — it turns on the two lights only if there isn’t enough ambient light to begin with.

Eve's Motion Sensor is exactly such a device. It reliably tracks room occupancy and light levels, works with almost any smart home platform through the Matter standard, and triggers automations ...

Aqara’s Thread-based Motion and Light Sensor P2 ($33.99) has been on my smart home wish list since it was announced way back in 2022 — and now, it’s finally here.
