Water Level Sensor Circuit Diagram
The sensor can be easibly made out of a small piece of pcb that is etched with the proper pattern.
Water level sensor circuit diagram. The decoupling capacitor c3 is a 100uf 16v electrolytic capacitor. Water level sensor circuit diagram. The logic implemented in this circuit is 555 timer is enabled when its reset pin is connected to logic high. It is also possible to connect several sensors to the water level monitor circuit.
Whenever tank gets filled we get alerts on particular levels. Here we have created 4 levels low medium high and full we can create alarms for more levels. Overflow of water is definitely a major problem nowadays. This is the circuit diagram of a simple corrosion free water level indicator for home and industries.
Water level indicator and alarm using uln2003. 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. But initially it is connected to ground. In fact the level of any conductive non corrosive liquids can be measured using this circuit.
The circuit is based on 5 transistor switches. 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. Water level indicator circuit liquid level sensor with alarm.
This simple transistor based water level indicator circuit is very useful to indicate the water levels in a tank.
