How to Make a Light Sensor Circuit with Adjustable Sensitivity Circuit Diagram In this project, you will build a touch sensor circuit. It's a cool and simple circuit that allows you to control an LED with the touch of a finger. And you only need three components, how cool right? You can build this circuit if you're a total beginner. The Touch Sensor Circuit Diagram. The 330K Ohm Resistor and LED can be replaced with virtually anything to trigger a signal or an event. For example, a 9 Volts Relay would be used to make an absence-of-light activated switch. To make this circuit operate in reverse (the LED turns on when there is light), simply just exchange the positions of the Variable Resistor and the LDR. Hook up your circuit according to the "DARK DETECT" schematic below. When properly implemented, the absence of light will turn the LED on. When sufficient light shines on the LDR, it turns off. Light Circuit Diagram: Reverse R2 and LDR to detect light or dark. Light Sensor Circuit Explanation
Current sensor circuits are used extensively in systems such as battery management systems in order to detect the current to monitor for overcurrent, a short circuit, and the state of charge of the battery system. It is low cost and relatively simple to implement. The second approach is using a hall effect sensor. This is used more for high
3 Simple Proximity Sensor Circuits Circuit Diagram
I want to make a simple automatic hand senetizing machine using - IR sensor module, motor pump, spray nozzle and timer circuit. Working of circuit : when ir module sense hand it turns on pump. The pump is connected to a nozzle spray pipe and it spray senetizing liquid on hands for few seconds (1-10) then the spray process will stop
About: HC-SR04 Ultrasonic Sensor is a simple ultrasonic sensor that can measure distance up to 400 cm. The sensor has 4 onboard pins that connect to a microcontroller like Arduino.d Waves. Objective: To make a circuit using an Ultrasonic sensor and Arduino which indicates the object in front by producing a beep sound. This circuit can act Simple Water Sensor: I will Teach you how to make a simple water sensor circuit . Projects Contests Teachers Simple Water Sensor. By Cyberscann54 in Workshop Science Here is how to setup the circuit to run on 12 volts from a car battery the circuit is still the same just some resistors are added to the probes to protect the transistor and a
Simple Light Detector With Sensitivity Control Circuit Diagram
In this tutorial, we are going to make a Simple Water Level Sensor Or Liquid Level Detector circuit. This circuit measures or detects a required level of water, liquid, or any fluid. The circuit diagram is quite simple with only a few components but it can perform a great number of tasks as a monitor for the desired level of any fluid.
