These sensors use infrared, radar, and sound waves to detect changes that mean someone or something is in the space. Use cases: If someone passes into the hallway, turn on a light.

While PIR sensors can be used with Arduino and other microcontroller boards, those best-suited for hobby use are smart enough to perform simple tasks without any programming.

The robot uses a whopping 32 IR sensors to follow a black line across a concrete workshop floor, adjusting its path using a steering motor salvaged from a power wheelchair.

Ever wonder how to calculate revolutions per minute using a microcontroller? This project shows you how by purposing an IR emitter and detector and a computer fan. As the fan blades spin they disru… ...

It uses an infrared sensor to measure the temperature of an object and is FDA-certified to monitor body temperature. We show you how to use the Google Pixel 8 Pro's temperature sensor.

If your phone does not have an IR blaster, you can still use an external IR blaster device: Connect the External IR Blaster: Connect the external IR blaster to your phone via a USB cable or Bluetooth.

Why Your Smartphone Needs an Infrared Sensor You could use a heat sensor to check your house for leaks, for instance. But mostly, it's a lot of fun.

Enhanced Vision Systems (EVS) use infrared sensors to provide pilots with increased situational awareness in low-visibility conditions, day or night. EVS cameras detect the heat of objects ...
