How to Make a Municipal Water Supply Sensor, Pump Controller Circuit

Last Updated on February 17, 2018 by Admin 7 Comments

The submit describes an easy water sensor with pump starter circuit for changing a pump motor throughout municipal water supply periods.

water2Bsensor2Bcircuit2Butility
The circuit design of the offered municipal water sensor with pump starter is very easy as might be observed in the demonstrated diagram.
A Darlington TIP 122 transistor turns into the main active sensing device in the circuit. The device being a Darlington is extremely delicate therefore evolves into in particular suitable for the application.
Its base and the positive DC are with each other clamped as probes across the water pipe mouth where the incoming utility water is meant to be felt.
In absence of water the probes stay separated with air gap which provides a very high resistance across the probes which often retains the transistor/relay stage turned off.
The 10uF capacitor at the base of the transistor makes certain that the transistor would not get rattled or upset with external noises seeking to create way by means of the sensor wires.
When utility water supply is linked to, the pipe mouth starts throwing water into the adjoining tank, the speed of the water by way of pipe brushes across the probes producing a comparatively low resistance across it.
This low resistance permits the positive DC to achieve the base of the BJT initiating it into conduction...the transistor currently performs and switches ON the relay, the relay contacts shift position and turn on the linked pump.

About Admin

Hey friends, Thanks a bunch for stopping by this site! I am an engineer with a Bachelor of Engineering in Electronics and Telecommunication. One of my passions is gathering information from all sorts of electronics books and tutorials. I then take that information and compile it into a language that is super easy to understand. My goal is to make those complex electronics circuit concepts and technical terms much more accessible for all the new and budding electronics engineers out there. I can also design customized circuit diagrams as required by the users.
If you have any questions related to this field, please do not hesitate to drop a comment! I am always here and ready to help you out with any queries you might have. I cannot wait to hear from you!

    Hi
    I want muncipal water sensor, that it open the tap as soon as it senses the moisture or water flow from corporation pipe. Once it reaches the top level of the tank it shut off the valve.

    I want to know were I can buy the kit & install it .
    Power can be via solar & battery

    I do not want motor circuit to be attached. Just need only automatic on & off for ground water tank

      Hi, you can use the above shown circuit for opening the tap…the motor can replaced with the tap valve.
      for shutting off the tap you can use another similar circuit for closing the valve. the sensor of this circuit could be positioned over the tank brim
