Advanced Flame Sensor

From the shop's description

This is high accuracy flame detector module. It is used for detecting direct fire (as it detects fire radiation). The module uses 5 flame sensors. It can output both analog and digital signals. The sensitivity of the sensor can be adjusted using the on board potentiometer. The sensor have a wide detection angle (more than 120 degree) and 5 LED indicators (one for each sensor). Specification Input Voltage: 3.3V~9V Dtection Range: ~ 1.5 meter Detecting Angle: >120 degree Wavelength Detection Range: 700:1100 Features Analog / Digital outputs On-board potentiometer for adjusting sensitivity Wide angle detection LED indicators Pin Definition GND: Ground VCC: Input voltage (3 : 9v) A1, A2, A3, A4, A5: Analog output D1, D2, D3, D4, D5: Digital output
