Air Humidity and Temperature Data Logger

March 22, 2013 By: admin Category: Data Acquisition, Measurement, Monitoring, PIC No Comments →

This temperature and air humidity data logger is built based on PIC16F876A microcontroller and SHT11 sensor. The sensor provides accurate measurement and is fully calibrated (no need to calibrate from user). The logger can measure temperature with range from -40°C to 99°C and Humidity from 1 – 99% with resolution 0.1°C temperature and 0.1% RH. […]

AVR Digital Stethoscope

February 11, 2013 By: admin Category: AVR, Data Acquisition, Detector, Measurement, Microcontroller No Comments →

This digital stethoscope can be used as computer aided diagnosis (CAD) applications for the detection of cardiac murmurs. It can assist physicians in analyzing cardiac signals in real time during auscultation to reduce the risks of not detecting heart murmurs conditions. The Stethoscope system is built based on ATmega644 AVR microcontroller and custom-built sensor to […]
