The logic implemented in this circuit is 555 timer is enabled when its reset pin is connected to logic high.
Water level sensor circuit diagram.
Overflow water tanks eventually lead to loss of water and natural resources as well.
In fact the level of any conductive non corrosive liquids can be measured using this circuit.
The sensor can be easibly made out of a small piece of pcb that is etched with the proper pattern.
Water level indicator and alarm using uln2003.
The circuit is based on 5 transistor switches.
Water level sensor circuit diagram.
But initially it is connected to ground.
Overflow of water is definitely a major problem nowadays.
The decoupling capacitor c3 is a 100uf 16v electrolytic capacitor.
Are you looking for an electronic solution to resolve this issue.
When the water level is maximum this pin is enabled and this drives the 555 timer into astable mode.
When water level reaches to point a circuit with red led transistor q1 gets completed and red led glows.
It is also possible to connect several sensors to the water level monitor circuit.
This is the circuit diagram of a simple corrosion free water level indicator for home and industries.
