An IR sensor module has two important parts: an IR transmitter LED and an IR receiver LED. The transmitter LED sends out invisible infrared light, and if this light bounces off an object in front of it, the receiver LED detects it. The IR module is used in many DIY projects, like line-following robots,...

In today's time, IR communication is widely used in many devices in different areas to control them wirelessly. IR Technology has various useful applications in our day-to-day life appliances such as TV remotes, ACs, infrared cameras, and temperature sensors.  But what if in case your IR remote stops working and you won't able to...

The TSOP38238 is a generic infrared (IR) receiver diode commonly use inside IR remotes to capture the IR signals and decode them into digital signals. This receiver diode is capable of capturing IR signals sent by remotes operating at a frequency of 38kHz. Many commonly used remotes in India, such as those for TVs...

In this tutorial, we are going to make Digital Tachometer using an IR Sensor with the help of Arduino for measuring the number of rotations of the rotating Motor in RPM. Here we have interfaced the IR sensor module with Arduino and the 0.96 Inch OLED display to display the RPM count. The IR...

In this project, let’s see how to make a simple bidirectional people counter using IR Sensors and Arduino Uno. This project will help learner to understand the working and application of IR sensor. The IR sensor is simple and powerful with wide variety of applications. This project will also help the user to understand logic...
