Here is a simple proximity sensor circuit which shows proximity of an object by LED bar graph. Also, you will see two other simple proximity sensor designs. Proximity sensors are devices that detect the presence of an object within a certain range without any physical contact. They are widely used in various applications such as […]
Let’s designing a PIR motion sensor circuit that uses a Passive Infrared (PIR) sensor to control a buzzer through a 555 timer for motion detection applications. Here’s a step-by-step guide to creating this circuit: Working Principle of PIR Motion Sensor: A Passive Infrared (PIR) motion sensor detects motion by sensing changes in infrared radiation. Here’s […]
Creating project like air quality monitoring system is a great way to keep track of environmental conditions in your area. This article will help you through the steps of setting up a system using the XIAO ESP32C6 board, various sensors, and the Blynk IoT platform. Here’s a detailed breakdown of the components and steps involved. […]
A decoupling capacitor is a capacitor used in electronic circuits to decouple one part of a circuit from another. It serves two primary functions: Filtering out Noise: It filters out high-frequency noise or transients on the power supply lines. Stabilizing Voltage: It provides a local reservoir of charge to stabilize the voltage supplied to an […]
Let’s understand the SMPS Block Diagram working. A Switch Mode Power Supply is an electronic power supply that incorporates a switching regulator to convert electrical power efficiently. Unlike linear power supplies, which convert excess energy into heat, SMPS circuit uses a switching element that rapidly turns on and off to regulate the output voltage and current. […]
