In this project, we built an Automatic Wireless Water Pump Controller, named Varun. The circuit automatically turns on and off the pump that fills the tank by monitoring the level of water inside it.

Here is an intelligent scanned water-level indicator-cum-pump controller circuit (Fig. 1) that utilises just four wires to the overhead tank to indicate nine different levels. Circuit diagram for the ...

Water Level Controller Circuit Diagram: Circuit Components: At89c51 controller At89c51 programming board. 16*2 LCD 5V Relay Bc547 (NPN) transistors – 5 Resistors (1K) – 4 Resistor – 330 ohm AC Motor ...

Here’s a circuit for an automatic water pump controller that manages the operation of a water pump motor. The motor automatically turns on when the water level in the overhead tank (OHT) drops below a ...

As shown in the water level controller circuit given below, Ultrasonic sensor module’s “trigger” and “echo” pins are directly connected to pin 10 and 11 of arduino.

Learn how to use logic gates and circuit diagrams to create a simple calculator that can perform addition and subtraction with four-bit numbers.

It is built around an popular IC from the somewhat antiquated 4000-series logic family: the 4093. This IC contains four inverted-output AND gates (NAND gates) with Schmitt-trigger inputs. If water is ...

Learn how to design a logic circuit that performs a specific boolean function using boolean algebra, logic gates, and circuit diagrams.

Schmitt Trigger gate is a digital logic gate, designed for arithmetic and logical operations. It provides OUTPUT based on INPUT voltage level. A Schmitt Trigger has a THERSHOLD voltage level, when the ...
