LED Street Lights with Auto Intensity Control by Arduino Projects

Arduino based LED Street Lights with Auto Intensity Control The main goal of this project is to control the automatic intensity of the street lights using an Arduino board. This project uses LED lights instead of HID lamps in streetlights. An Arduino board is used to control the intensity of the lights by developing PWM signals … Read moreLED Street Lights with Auto Intensity Control by Arduino Projects

8051 microcontroller Projects based Heart Rate Monitor HRM with SMS Alert

Heart Rate Monitor HRM with SMS Alert This project is 8051 microcontroller Projects based Heart Rate Monitor HRM with SMS Alert. Heart rate is sensed from the fingertip using a phototransistor / IR LED pair. This method is called photoplethysmography. Photoplethysmography is the volumetric assessment of an organ/tissue using light. IR reflection photoplethysmography is the … Read more8051 microcontroller Projects based Heart Rate Monitor HRM with SMS Alert
