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 ...

Have you ever wondered how speed guns measure the speed of moving vehicles or how an athlete's sprint speed is recorded? Normally these speed sensors work with radar or laser technology to bounce back ...

Arduino Sensor Interfacing (Flex sensor, IR Sensor, PIR ,BMP180, LM35, LM75 Refer below Tutorials for external sensor interfacing with Arduino - Visit for simillar ...

Controlling an LED with Arduino Using an IR Sensor An Infrared (IR) sensor is a commonly used device for proximity detection and object sensing. When combined with an Arduino and an LED, it can create ...

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 ...

Photoelectric sensors detect objects and surface changes using variations in optical properties. Each sensor includes a light emitter and a receiver, with most relying on infrared light. In optical ...

Here we are presenting an Arduino based low-cost Proximity Sensor Switch to control electric load wirelessly. But before we start to learn how to make this, let’s understand why we need it? Workers’ ...

Some readers may recall building a line-following robot during their school days. Involving some IR LEDs, perhaps a bit of LEGO, and plenty of trial-and-error, it was fun on a tiny scale. Now imagine ...
