This is a library for the laser particle sensor module PM2005 manufactured by Wuhan Cubic Optoelectronics. The PM2005 module counts airborne particles of different sizes in catagories of 0.3, 2.5, and ...

Stratio, a Korean deep-tech startup founded by three Stanford Ph.D. graduates, is introducing what it claims is the first germanium-based short-wave infrared sensor designed for large-scale commercial ...

Just about every “getting started with microcontrollers” kit, Arduino or otherwise, includes an ultrasonic distance sensor module. Given the power of microcontrollers these days, it was only a matter ...

Raspberry Pi launched a follow-up to its Camera Module 3 with the Camera Module 3 Sensor Assembly. Now, Raspberry Pi users can put the camera sensors into their own custom form factors. The move ...

The visible light spectrum that humans perceive spans only a small portion of the electromagnetic spectrum — roughly 430 to 750 THz, corresponding to wavelengths of ~400-700 nm. Just beyond this range ...

The TCRT5000 sensor is an infrared reflective sensor. This library is written to use with a TCRT5000 breakout's analog output and handle a threshold in software. These breakouts have typical two ...
