air humidity logger

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. […]

February 27, 2013 By: admin Category: Control, Monitoring, PIC No Comments →

Gas Boiler Controller

This Room Thermostat provides better controller for gas boiler. Instead using water temperature inside boiler, the device uses room temperature as parameter to switch boiler on or off through relay. The project is built based on PIC16F74 and uses 1–wire digital thermometer IC, Maxim DS1820, to sense room temperature.
