Arduino Based Air Quality Monitoring Circuit check bad stuff in air like CO2, VOCs and PM. It uses Arduino microcontroller and many sensors to check air quality. Arduino read sensor data and then send to computer or cloud or show on small screen (LCD). People like this design because it is cheap, easy and useful […]

For fun and learning project. We learn basic electronics, coding and sensor uses. Here we will learn How to Create a Water Level Sensor Circuit with Arduino This guide teaches us how to make water sensor. It is good for stopping overflow, checking water in tank or auto watering plants. We can use Arduino Uno […]

This article show how to make Arduino Temperature Controller Circuit using DC Fan Arduino UNO, LCD, transistor, DHT11 sensor and with few resistors. It show temperature and fan speed on LCD and control fan speed based on room temperature in home or office. Fan turns ON and OFF automatic when temperature goes above or below […]

This project show How to Measure Humidity and Temperature using Arduino and DHT11 DHT11 give temperature in Celsius and humidity in percent. Arduino read sensor and show on LCD. This circuit is good for checking room, garden or weather. It is also good for learning how sensor and Arduino work together. Coding: Code Explanation: Circuit […]

Ultrasonic sensor use high sound wave to find distance. It send sound and wait for echo to come back and then it measures time. With Arduino help we can make system to know how far object is. This project for Distance Measurement Circuit using Ultrasonic Sensor and Arduino shows basic of ultrasonic sensor, Arduino code […]

LPG Gas Leakage Detector Circuit using Arduino is important safety tool which can stop accidents. This project uses Arduino to check LPG gas in air. If gas level goes too high then buzzer make sound and LCD show warning. Through this circuit people know danger fast. Code Programming and Explanation: Code Explanation: Circuit Working: Parts […]
