Digital Thermometer for Car, DS18S20

May 28, 2013 By: admin Category: AVR, Measurement, Monitoring No Comments →

This digital thermometer is built as additional feature for car without outside temperature indicator. The project is built based on Attiny2313 microcontroller and DS18S20, 1 Wire Parasite-Power Digital Thermometer sensor from Maxim.

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. […]

PIC16F74 Room Thermostat for Gas Boiler

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

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.
