Interfacing of Humidity Sensor using 8051 Microcontroller

We never know the level of humidity in the atmosphere and its variations. It would be difficult to adjust the air cooler in such circumstances and instead of cooling the room in summer it would make very uncomfortable while the humidity goes up because of water particles are constantly released to the room by the cooler water pump. This project will fade away all the previous bad experiences that switch off releasing water particles and brings smile on the face just by adding a moisture sensor. The motor used represents the water pumping motor of the cooler. Initially a value is fixed and if the humidity goes up the specified value, then microcontroller is used to interface the sensor and it will switch on the cooler fan if the value goes higher than the pre-specified value i.e. humidity present in the room is higher and cooler fan should get ON and it will turn ON the cooler fan and if the value printed on LCD is below the pre-specified voltage then it means humidity present in room is quite low and we don't require any fan to be turned ON in our room so our system will turn OFF the cooler fan.
