On this tutorial we will going to wire the Heart Beat Sensor using Arduino & Processing. The pulse sensor module is an open source heart rate detection device that detects the hearth pulse rate through the light transmittance change with
Working on Dust Particle Optical Sensor with Arduino
Sharp’s GP2Y1010U0F is an optical air quality sensor it was designed to sense dust particles. An infrared emitting diode and a photo-transistor are diagonally arrange into this device, to allow it to detect the reflected light of dust in the
