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 ...

The smart car parking system uses an ESP32 microcontroller, an IR sensor, a servo motor, and an Arduino Cloud account to efficiently manage parking spaces, reduce traffic congestion, and improve air ...

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 ...

The sensor continuously sends out infrared light and measures how much of that light is reflected. When a reflective object is within its set detection range, it returns a low signal. The Arduino ...

with a set threshhold value to determine when the photogate has been passed infront of. Then it waits for the Arduino_Nano_Photogate_Sender to report the threshhold has been passed, and displays the ...

Electronic enthusiasts may be interested in a new open source infrared sensor which has been created to support both Raspberry Pi and Arduino powered projects. The IR Detector proximity sensor has ...

Abstract: Presence of doctor is essential for proper patient care. But he cannot be present on each and every place to provide medication or treatment. So remote monitoring of a patient is the right ...

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 ...
