An preexisting circuit for an IC 555-based water level controller may be modified to include the dry run protection, as seen below: In the schematic above, the dry run function operates as follows: The IC’s pin #2 loses its positive voltage whenever the water level falls beneath the “low level” probe. As a result, pin … Read more
So you might be wondering what a water level indicator is. Well it is actually an electronic circuit that helps you see the different levels of water inside a tank. This works by using water sensors that are set up in a stepwise manner at various depths inside the tank. When the water level goes … Read more
The ULN2003 is a chip which contains seven separate sections, each made up of special transistors called Darlington pairs. These pairs are designed to manage moderate amounts of electrical current, up to 500 milliamperes, and can work with voltages as high as 50 volts. You can use the ULN2003 to create a complete and automated … Read more
You can make a basic device to stop your water tank from overflowing using just one IC 4049 chip. This device, not only prevents overflow but also shows you the water levels as the tank fills up. Circuit Diagram How the Circuit Works When the water gets to the top of the tank, a sensor … Read more
The design we’ are talking about can be made with the IC 4017 chip and some logic gates, as shown in the diagram. Mr. Robert asked for help with this fourth circuit. And heres what he needs: I’ve just found this website with its circuit designs and I’ am hoping you can help me. I … Read more
In the discussed circuit, a logic IC 4093 is utilized. Commonly, the water we receive in our homes, which isnt pure, offers little resistance to electricity. To put it plainly, water can conduct electricity, though the effect is very slight. Typically the resistance of household tap water falls between 100 K and 200 K ohms. This level of … Read more
