Initialization: The Arduino initializes the pins for the flame sensor, built-in LED, and external LED, and begins serial communication. Flame Detection: The flame sensor reads the presence of a flame ...
Arduino Flame Sensor Code. The code for interfacing the flame sensor is very simple and easy to understand. We just need to define the pin through which the sensor is connected with the Arduino. Once ...
Arduino based Fire Alarm – Circuit and Working. Fig. 2 presents the circuit diagram for the fire alarm using a flame sensor and Arduino Nano. The system is powered by a step-down transformer (X1), a ...
This line initializes the serial communication at a baud rate of 9600 bits per second. Serial communication is used here for debugging purposes. You can view the messages sent by the Arduino on the ...
Calibration of the voltage to process temperature data is carried out by the Arduino running the program serial_plotter.ino. After calculation of the temperature, data is plotted on the Serial Plotter ...
However, to transmit serial data (such as debugging information) wirelessly, we need another solution. IoT devices operating remotely ‘in the field’ benefit from the ability to perform software ...
