An infrared proximity sensor, or IR Sensor, is an electronic device that emits infrared light to detect objects and motion in Arduino projects. This interfacing of the IR sensor module with Arduino is ...

In this tutorial, we'll guide you through interfacing an Arduino with an ultrasonic sensor to measure distance and show it on the Serial monitor. We'll start by explaining how to interface the ...

Displays the current CO₂ level so you can quickly check if the current conditions are safe. Records CO₂ levels over time. Good for tracking regularly-scheduled events (eg. school & work). Accurate ...

I recently had to build an infrared close proximity sensor that could tell if something was dropped in a parcel delivery drop box. After some searching, I ended up using a microcontroller and a piece ...

Electronic systems can help the visually impaired. This innovative project combines an Arduino Nano, a TCS34725 color sensor, and a buzzer to assist users who have trouble seeing colors. How can a ...
