It really is a hands-on way to learn electronics and programming while building a useful gadget. Get your Arduino board and gas sensor to start creating your smoke detector today. Write a code for ...

Out of all the parts planned to be used, only the Arduino board, MQ-2 sensor, and buzzer are necessary, for a total of $7.43. Those are non-bulk prices and with slightly upgraded shipping; if you were ...

Arduino Nano is a microcontroller board that is used to perform various tasks in different circuits. The microcontroller that Arduino Nano uses is ATmega328P. We burn a C Code on this board to tell it ...

I will attach all the schematics and the PCBs design for the project. I will start by doing the PCB design for the smoke sensor detector. Components: Arduino UNO; Power Supply; Smoke Sensor (MQ2) ...

Working of this Smoke Detector Alarm Circuit is easy. In this project, we have used transistor operating properties to work this circuit as a smoke detector. As we already know that we have used a ...

In some regions of the United States, such as California and Massachusetts, laws require photoelectric smoke detectors. The reference design of the smoke detector, CN0537 by Analog Devices, is ...

Smoke Detectors are very useful in detecting smoke or fire in buildings, and so are the important safety parameters.In this DIY session, we are going to build a Smoke Detector Circuit which not only ...
