This bachelor Thesis talks about developing a thermostat. It is a thermostat with possibility of remote control. The base of thermostat is credit card sized computer Raspberry Pi. We use digital thermometer for temperature measurement and relay for heating control. To avoid over switching of relay we use a hysteresis loop. We can also control digital input and outputs.
For remote control of thermostat we use SMS messages. For easier control we have developed Android application, which allows us to use graphical interface for creating SMS messages in order to control the thermostat.
