Design and implementation of heated system with monitoring based on Bluetooth technology

الملخص EN

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 control the temperature and level of the water.

also, the mathematical models for operation principle 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 opened and closed of solenoid valve.

Third : the sensor (ds18b20) is used to sense the temperature to prevent excessive in temperature that can lead to serious accidents.

the android device communicating with a Bluetooth module connected to an Arduino Uno microcontroller.

the Andriod 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 technique is used to turn on and off the system.
