Flame Detector Sensor YL-38

Setelah berekspreimen dengan line tracing, dilanjutkan dengan fire detector. Produk yang akan saya coba kali ini dari pabrikan china dengan seri YL-38. Sensor diterima tanpa datasheet tapi dari konfigurasi sudah secara jelas tergambar kalau produk ini mempunyai pin untuk power, 1 DO dan 1 AO. Prinsip kerja dari sensor ini adalah mendeteksi temperature dimana dia akan menghasilkan digital output sesuai dengan threshold yang diatur oleh potensiometer. Untuk program, bisa kita ambil referensi dari hobbycomponents seperti yang dibawah.

This is a simple example of how to use the HobbyComponents Arduino flame detection
module (HCARDU0024). The sensor has two outputs, an analogue output that is
dependent on how strong a flame is detected, or a digital output that will go high if
a flame is detected above a threshold set by the modules potentiometer.

This example program reads the status of both sensor outputs and outputs the result
to the UART.

SENSOR PINOUT:

PIN 1: Analogue out
PIN 2: Ground
PIN 3: +5V
PIN 4: Digital out
