An automatic room light controller with people counter. Using arduino, counts the number of people in the room, with the help of IR sensor, turns an AC - DC LED bulb ON only when at least when one ...

Analog Speedometer Using Arduino and IR Sensor. This project uses an IR sensor to measure the speed or RPM of a moving object, such as a motor or vehicle wheel. The speed is displayed in both analog ...

Arduino Motion Sensor – Circuit and Working The circuit diagram of the automation device using a motion sensor is shown in Fig. 2. It consists of an Arduino Nano board (MOD1), a PIR sensor (S1), a ...

After some searching, I ended up using a microcontroller and a piece of code borrowed from the web that I tweaked and adapted. The microcontroller-based concept was chosen because I wanted to scale ...

Infrared (IR) sensor. I’ve seen numerous references to IR sensors, usually with an IR beam directed across the track. The receiver is positioned to detect a reflected beam when a train passes. These ...

This paper presents an implementation of smart, and inexpensive human body temperature detector by using portable electric system based on Arduino UNO, and MLX 90614 IR temperature sensor. The ...
