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. [...]
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.
PowerManager allows you to monitor and control your home power through a web browser on a local area network (LAN). You can turn on or off any devices that plugged to PowerManager’s outlets with the click of a button on a webpage. The system based on AVR ATMEGA644 microcontroller and ENC28J60 Ethernet controller. This embedded [...]
