How to Measure Humidity and Temperature using Arduino and DHT11
This project show How to Measure Humidity and Temperature using Arduino and DHT11, as this DHT11 give temperature in Celsius and humidity in percent and then Arduino read sensor and show on LCD. Also, this circuit is good for checking room, garden or weather and furthermore, it is good for learning how sensor and Arduino […]
Distance Measurement Circuit using Ultrasonic Sensor and Arduino
Ultrasonic sensor use high sound wave to find distance, also 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, as this project for Distance Measurement Circuit using Ultrasonic Sensor and Arduino shows basic of ultrasonic sensor, […]
LPG Gas Leakage Detector Circuit using Arduino
LPG Gas Leakage Detector Circuit using Arduino is important safety tool which can stop accidents, as this project uses Arduino to check LPG gas in air. Also, if gas level goes too high then buzzer make sound and LCD show warning, hence, through this circuit people know danger fast. Arduino Code: Code Explanation: Circuit Working: […]
Digital Thermometer Circuit using Arduino and IC LM35
This project builds a Digital Thermometer Circuit using Arduino and IC LM35, as first, the Arduino reads the voltage from the LM35 sensor, and then it converts this voltage into a temperature value. Moreover, people have used thermometers for a long time to measure temperature and then finally, the measured temperature appears on a small […]
Fire Alarm Circuit using Thermistor and IC 555
The Fire Alarm Circuit using Thermistor and IC 555 help to find and warn people about fire, as this design uses IC 555 and thermistor to check temperature change and maybe fire. Furthermore, thermistor is special part which feels the temperature change, also circuit is easy to make and thermistor changes resistance with heat and […]
