A basic electrical circuit that detects the existence or intensity of air flow is known as a simple air flow detection circuit. These circuits are frequently used to monitor air flow in appliances and DIY projects. Here, we are constructing a very basic circuit to find the existence of air movement. Here, we are detecting […]

Simple Light Detector Circuit using Wheatstone Bridge
The ability of a Light Dependent Resistor (LDR) to alter its resistance in response to light intensity is used in a simple wheatstone bridge light detector circuit. One arm of the wheatstone bridge has a series connection between the LDR and one of the fixed resistors. In the opposing arm, a series connection is made […]
Simple Tilt Sensor Switch Circuit
A simple tilt sensor switch circuit regulates the ON/OFF state of another component, such as an LED or buzzer using a tilt sensor. In this project, a tilt sensor is used in a circuit as a miniature seesaw switch. Assume there is a metal ball within the tilt sensor. The ball slides down and makes […]
Simple Missing Pulse Detector Circuit
An electrical circuit intended to recognize missing pulses within a sequence of incoming pulses is called a basic missing pulse detector circuit. The most often used part of this function is a monostable multivibrator which is a IC 555 device. This indicates that each time it is activated, it produces a single pulse. In the […]
Simple Darkness Detector Circuit
An LED is turned on by a light dependent resistor LDR in a simple darkness detector circuit when it becomes dark. In the circuit of a voltage divider, the resistor and the LDR are linked. Because of the low voltage at the transistors base in strong light, the transistor remains off. As night falls, the […]
Motion Detector Circuit using IC 555
This simple design for a motion detector uses an IC 555 to detect human trespassing from a distance. Usually, there are two major components to this circuit: Transmitter: The IC 555 is used in this part as an astable multivibrator, in other words it produces a constant frequency specific square wave. This high frequency beam […]
