c code for 8051 microcontroller water level controller

It is powered up with 5V dc and is interfaced with microcontroller. This pulse is received by ultrasonic receiver and then on/off the connected things. The ultrasonic transmitter sends the high frequency sound pulse and this pulse is reflected after the collision of desired object. This ultrasonic module consists of ultrasonic transmitter and ultrasonic receiver. Ultrasonic Module: In this contactless liquid level controller system, the ultrasonic module is used for on/off the motor or pump when liquid or water level is falls or up the desired level. It works on the principle of mutual induction. Transformer: Because this contactless liquid level controller system is directly powered up with 220V ac supply, therefore transformer is used for step down the 220V ac into 12V ac.

Here is the block diagram of contactless liquid level controller system with all essential components,įigure 1 Block Diagram of the Contactless Liquid Level Controller System Components List with Detail of Contactless Liquid Level Controller System Block Diagram of the Contactless Liquid Level Controller System In this system, ultrasonic sensors are installed outside the liquid or water tank, in other words they do not have any link with water or liquid, therefore they do not create the installing or maintenance problem and this system timely on/off the motor or pumps. Here we have designed a system that is called a contactless liquid level controller system with the help of transformer, pic microcontroller 18F452, ultrasonic sensors, relay, LCD display and voltage regulator. The inside limit switches or sensor creates installing and maintenance problems.

SO many control systems are available in market such as a manual or automatically on/off system and with these systems sensors or limit switches are installed inside the water or liquid tank. But with these tanks, motor or pump control system is very important because if these are not timely on /off then so much quantity of liquid or water could be wastage on daily basis. Water or any liquid saving tanks are commonly used on commercial or industrial level and with these tanks motor or pumps are normally used for maintaining the desired liquid level. Contactless Liquid Level Controller System: Contactless liquid level controller system is very significant system for maintaining the desired level of any liquid such as water or oil in a close tank.
