If we want to know how hot and humid it is, we can use an Arduino, a sensor called DHT11, a resistor and a LCD display to show the numbers. The DHT11 sensor will measure the temperature in degrees Celsius and the humidity as a percentage. The Arduino will understand the sensor and show the […]

Distance Measurement Circuit using Ultrasonic Sensor and Arduino
Ultrasonic sensors use high-frequency sound waves to detect distance, then they measure the time it takes for the echoes to bounce back. When combined with the Arduino microcontrollers computing capacity, we can build a system that can precisely calculate an objects distance from us. This assignment will examine the fundamentals of ultrasonic sensors, the necessary […]
LPG Gas Leakage Detector Circuit using Arduino
The LPG gas leakage detector is an essential safety tool that may stop incidents and tragedies. An Arduino microcontroller is used in this project to track the amount of LPG gas in the surrounding air. People are instantly alerted to the possible risk when the gadget sounds a buzzer and shows a warning on an […]
Simple Air Flow Detection Circuit
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 […]
