AVR Thermostat

This thermostat is built around an ATMega164 and a TC1047A temperature sensor. It controls your furnace and air conditioner. It is not programmable, although it has a clock and is capable if some additional code were written (any volunteers?). The unique feature is that instead of a bunch of buttons and switches, I used a single pushbutton rotary encoder, for a very simple user interface. The ATmega164P has ...

A m -Controller Based Thermostat Using Atmel AT90S8535 microcontroller

Introduction The goal of our final project was to design a thermostat using an Atmel AT90S8535 microcontroller. The thermostat was to compute the current temperature once per second and then send an on/off signal to a heating device which would then regulate the temperature to a desired target temperature. In addition, the thermostat was required to keep a time of day clock, as well as record the maximum an ...

Room thermostat with colour LCD

Gas boilers are usually equipped with a simple sort of controlling element, but they regulate the amount of heating by measuring the water temperature inside the system. Without a proper room thermostat, that works on the principle of measuring the air temperature, is actually a waste of energy. This project offers a very simple and cost efficient solution for that. Hardware The heart of the unit is an 8 bi ...
