How to make automatic water pump : Aqua Float Switch Sensor
How to make automatic water pump : Aqua Float Switch Sensor . There is an automatic water pump controller circuit controlled by water pump motor.
The water in the overhead tank (OHT) becomes automatically below the lower limit. Similarly, filled with tank will switch off. Only a single NHD gate ICD (CD 4011) is made, and the circuit is simple, compact and economical.
It supplies 12V DC power supply and consumes very little power.Float level switch is a simple structure, easy to use level control device, it does not provide power, no complicated circuit, it has a mechanical switch than the average small size, long life and other advantages. As long as the material used in the correct shape and nature of any liquid or pressure, temperature can be used,
