Water Level Sensor Block Diagram

Water level controller block diagram the ultrasonic sensor senses the level of water in the tank by transmitting ultrasonic signals towards the tank.

Water level sensor block diagram.

The regulator 7812 stabilizes the dc voltage to 12v while the variable resistor pot hg. Bestar bpt 23cx in order to make a noise when a certain level of water is being reached. This simple water level indicator will activate an active buzzer e g. This unit comprises of the transformer bridge rectifier filtering capacitor and a voltage regulator in this work a 5volts and 12volts dc was used hence the need to use dual voltage source.

It also prevents dry run of the pump in case water level in underground tank goes below suction level. In this tutorial we are going to make a simple water level sensor or liquid level detector circuit. This circuit measures or detects a required level of water liquid or any fluid. The circuit diagram is quite simple with only a few components but it can perform a great number of tasks as a monitor for the desired level of any fluid.

Hello friends today in this video i have shown how to make a simple water level indicator. Block diagram tida 00317 level sensor header reference liquid sensor shields reference environment sensor liquid level sensing using capacitive sensing technology out of phase oop technique eliminates any proximity interference such as a human hand either nearby or in contact with the container rigid flex circuit allows the sensors to be. The water in the tank reflects back the ultrasonic signals which are received by the receiver. This water level controller circuit makes this system automatic.

Generally water stored in overhead tank is wasted due to over flow when the tank is full. The water level indicator circuit diagram monitors the level of water in the tank and simultaneously switches on the water pump whenever the water level goes low in the water tank. Water level alarm using micro controllers like 8051 and avr are shown in previous articles this article shows simple circuits of water level indicator with alarm. Because the water sensor and the command circuit are located on the same printed circuit board indicator together with its 9 v battery and the buzzer can be mounted in a compact case.

Parts list 4 220 ohm resistor 4 bc547 transistor 9v battery. The water level of the tank is indicated by using the 5 led s and if the water level in the tanker is full then the water pump is turned off completely.
