Feel free to modify the code to suit you, the pins I provided here will work "out of the box". The code was created for Arduino Uno, so keep in mind that other boards may have different pins. Just ...

Through this project tutorial, you can build a fire and smoke alarm system using Arduino UNO R4 that sends real-time SMS notifications. This means you will immediately get alerted even if you are far ...

Our neighbours smoke at the ... to build a smoking detector alarm based on PM values (only reasonable property of air I was able measure for this purpose). Current prototype is based on Arduino board ...

The alarm automatically switches off after a few seconds. Circuit diagram of the Arduino based visitor alarm is shown below. It is built around an Arduino Uno board (Board1), a reed switch (S1) and a ...

The embedded systems used to develop this fire alarm system are Raspberry Pi and Arduino Uno. The key feature of the system is the ability to remotely send an alert when a fire is detected. When the ...

and smoke. These sensors send data to an Arduino Uno R3 microcontroller and utilize it to determine the gas concentration and trigger security precautions. When the concentration exceeds a threshold, ...
