Window sensors are a critical part of any home security system. Learn how they work so you can ensure this last line of defense is there when you need it.

How do Roomba sensors work? The Roomba employs three types of sensors to navigate around the house: infrared sensors, photoelectric cells and a piezoelectric sensor.

I recently had a project where I needed such a sensor, and I picked up a TF-MiniS, which is a popular IR distance sensor. They aren’t very expensive, and they work serial or I2C. So how did it do?

Tire pressure sensors are a key part of ensuring drivers stay informed about the condition of this crucial piece of automotive equipment.

Here’s what we know about the MAX30105 air particle sensor. There are three LEDs inside this chip (red, IR, and green), and an optical sensor underneath a piece of glass.

Researchers have finally figured out how mosquitoes see humans in the dark: They detect infrared light the body generates via heat.

So how do those cameras work? By definition, a thermal camera is a non-contact device that detects infrared energy (heat in this case) and converts it into a visual image.
