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 ...

If you ever built a line following robot, you’ll be nostalgic about [Jeremy’s] light-seeking robot. It is a very simple build ...

Abstract: In this paper, Arduino based Smart Irrigation System using GSM Module and Sun Tracking Solar system has been explored. This system is hoped to be very convenient and affordable for the ...

This is a library for the Arduino IDE that helps interface with ST's VL53L1X time-of-flight distance sensor. The library makes it simple to configure the sensor and read range data from it via I²C.

Abstract: Light source and photodetector are necessary elements for liquid concentration sensing system. Normally, two different devices are needed to realize these functions. The coexistence of ...
