The main aim of this kit to design an electronic system that checks the person’s availability then turn on the devices if the person available. It also regulates between the devices depending on the temperature. It is an environmentally friendly kit that helps in saving power.
This device is an intelligent system that can control devices (namely heater, fan, A.C.) based on room temperature. When the room temperature is very low it turns on the heater to heat the room. At medium temperature ranges, it turns on the fan. At higher temperature ranges it turns on the Air Conditioner to cool the room.
The kit consists of a temperature sensor DS18B20 sensor to check the temperature continuously. The IR sensor arrangement manages to check the person’s entry and exit. The devices are controlled via relay arrangement with a relay driver installed.
