How to Use

In the case of working with a MCU:

• VCC ↔ 3.3V ~ 5.3V
• GND ↔ power supply ground
• AOUT ↔ MCU.IO (analog output)
• DOUT ↔ MCU.IO (digital output)

Note: the Flame Sensor is used for detecting fire without any fire-protection for itself, please keep distance from the fire to avoid damage.
