how to make water level alarm circuit using 555 timer

Water level alarm circuit

Description.

Water Level Alarm Circuit Using 555timer

               Here is a easy water level alarm circuit using of 555 timer that will produce an audible alarm when the water level reaches a preset level.The circuit can be powered of a 9V battery and is easy to use.

    The circuit is based totally on an astable multivibrator wired round IC1 (NE 555).The working frequency of the astable multivibrator right here will based on capacitor C1, resistances R1,R2 and the resistance throughout the probes A&B.When there is no water up to the probes, they will be open and so the multivibrator will now not produce oscillations and the buzzer will no longer beep.When there is water up to the tip of probes,
some current will pass by  the water, the circuit will be closed to some extend, and the IC will begin producing oscillations in a frequency proportional to that of C1,R1,R2 and the resistance of water throughout the probes.The buzzer will beep to point out the presence of water up to the position of the sensing probes.

     Water Level Alarm Circuit Working and Its Applications

Water Level Indicator:

            The water level alarm circuit is a easy mechanism to observe and point out the level of water in the overhead tank and additionally in the different containers.

Nowadays, all the householders/owners are storing the water in overhead tanks through the usage of the pumps.When the water is saved in the tank, no one can perceive the level of water 
and also, no one can comprehend when the water tank will fill.

Hence there is an overflow of water in the tank, so there is a wastage of strength and water. To get to the bottom of this kind of issues through the usage of the water level alarm circuit of a 555 timer it helps and indicated the level of water in the overhead tanks.

The price of the water level alarm circuit is low and beneficial for the overhead water tanks, swimming pools, boilers, etc..

The water level alarm circuits are used in the factories, chemical plants, and electrical substations and additionally in different liquid storage systems.

Notes.

·                                         The circuit can be powered of a 9V battery.

·         Assemble the circuit on a good quality PCB or common board.

·         The probes can be made of two insulated copper / Aluminium wires.

·                                       Place the probes at the position where you have to sense the level.

What is a Water Level Indicator?

           The water level indicator is described as a device which receives the signals about the water level in reservoirs or in tanks which is used in homes. By the usage of the water level indicator we can overcome the overflow of water from the tankers.
