12v Water Level Indicator Circuit Diagram. 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. Here we have created 4 levels low medium high and full we can create alarms for more levels.
In fact the level of any conductive non corrosive liquids can be measured using this circuit. 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. The following diagram shows the water level indicator circuit diagram consist of 4 probes which are placed in the overhead tank and interfaced with the port 2 of the microcontroller.
When there is enough water in the underground tank probes c and s are connected through water.
When there is enough water in the underground tank probes c and s are connected through water. The circuit is based on 5 transistor switches. This simple transistor based water level indicator circuit is very useful to indicate the water levels in a tank. Here we have created 4 levels low medium high and full we can create alarms for more levels.
