DESIGN AND IMPLEMENTATION OF HEATED SYSTEM WITH MONITORING BASED ON BLUETOOTH TECHNOLOGY

In homes and any processes industry, the main processes that need to be controlled are temperature and level of the water. This paper is focused on the design and implementation of an Electric Heated System that connects with their environment using actuators and sensors for sensing and controlling the temperature and level of the water. Also, the mathematical models for the operating principles are presented. The system used the Arduino UNO card which is a microcontroller board for controls 'ON’ and ‘OFF’ conditions of the heater and motor depending upon the temperature and level of the water in the tank. There are three sensors used with Arduino, First: the Ultrasonic sensor (HC-SR04) is used to measure the distance between the sensor and the object, and this distance is proportional to the level of the water. Second: Infrared sensor (KY-032) is used to control the drain of water by opening and closing the solenoid valve. Third: The sensor (DS18B20) is used to sense the temperature to prevent excessive temperature that can lead to serious accidents. The Android device communicates with a Bluetooth module connected to an Arduino Uno microcontroller. The android application is used for two tasks. First monitoring the value of the temperature and water level in the tank during the operation of the system, second the wireless communications technology is used to turn ON and OFF the system.
