This project uses an MQ2 gas sensor, relay module (for motor or exhaust fan), buzzer, and LEDs to create a complete gas leakage detection and alert system using Arduino. When gas concentration crosses ...
Nowadays, sensors play a major role in the safety and security of many different apartments, homes and offices by detecting smoke, fire, or gas and providing an alarm to the concerned person. That is ...
Arduino/NodeMCU programs that programatically calibrates the readings from a MQ2 & MQ135 sensors that detects smoke and other gases such as carbon monoxide, ammonia, methane in the air. The sensors ...
Abstract: The application of sensors in smart homes using Arduino to control equipment such as lights, fans, alarms, and so on. Sensors used in Arduino include LDR, Ultrasonic, DHT11, and MQ2. LDR is ...
Our Smart Home Using Arduino Uno R4 WiFi project is designed for home safety and convenience, integrating temperature, humidity, light, and gas monitoring. Using sensors like DHT11/DHT22, LDR, and ...
