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 ...

Morse-Talk helps non-verbal individuals communicate via Morse code. Arduino IDE code converts Morse to text on LCD. Python (VS Code) handles text-to-speech via Bluetooth and triggers GSM emergency ...

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 ...

If you’ve been watching Nintendo Switch 2 news like a hawk for the past few weeks, you may have spotted leaks about the new and improved Joy-Con controllers, and wondering just what an IR sensor is.

Infineon’s PASCO2V15 CO2 sensor is a compact and precise carbon dioxide sensor that uses photoacoustic spectroscopy (PAS) leveraging its built-in microphone and IR emitter to detect CO2 levels by ...

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 ...

STMicroelectronics’ STHS34PF80 ultra-low-power IR sensor with micromachined thermal transistors detects up to four meters without an optical lens. Developed as an alternative to passive infrared (PIR) ...
