Here is the circuit diagram of a simple steam sensor, wired around a handful of inexpensive components. This steam sensor can be connected to a microcontroller’s I/O port directly. The steam sensor ...

Temperature and humidity sensor (ENS210). Temperature, humidity, and air quality sensor (Bosch BME680). Temperature, humidity, and CO2 sensor (Sensirion SCD40). Light sensor (BH1750FVI). Contact ...

Is your heaving pile of electronic parts shrinking by the day as you finish old back-burnered projects and come up with new ones? Try an old pastime that never gets old: rolling your own sensors using ...

A camera’s image sensor is one of the most important pieces of tech to capture images. It’s the small element deep inside your camera that converts light waves into electronic signals that actually ...

This homemade parking sensor was developed using an Arduino, ultrasonic range finder and some other components to guide vehicle parking. One of the main materials used is the Arduino duemilanove which ...

Gas leaks can pose serious safety risks, especially in homes, kitchens, and small commercial spaces. In this project, you'll learn how to build a simple and budget-friendly gas leakage detector using ...

So we saw this tip come in and thought–oh, another POV device. We watched the video (embedded after the break), took a sip of coffee, then almost sprayed the beverage all over the computer when we ...

Tilt sensing isn't quite the novelty it once was, with all these new-fangeled controllers and laptops flooding the market, but as much as the execution might lack, or our child-like joy wane, we've ...
