It also regulate between the devices depending on the temperature. It is an environmental friendly kit which helps in saving power. This device is an intelligent system which can control devices (namely heater, fan, A.C.) based on room temperature.
When room temperature is very low it turns on the heater to heat the room. At medium temperature ranges it turns on fan. At higher temperature ranges it turns on the Air Conditioner to cool the room.
The kit consists of temperature sensor DS18B20 sensor to check the temperature continuously. The IR sensor arrangement manages to check the person entry and exit. The devices are controlled via relay arrangement with relay driver installed. The devices are managed on the basis of person availability and the temperature. The kit also helps in power management by ensuring efficient usage of the load unit as per the need. The kit can be used for automation in the offices etc.
