SP Electron Flame Sensor Infrared Receiver Ignition Source Detection Module (Pack Of 1) Electronic Components Electronic Hobby Kit

Indicator light: Green one for switch, red one for power. Built in a potentiometer for sensitivity control. On-board signal output indication, output effective signal is high, at the same time the indicator light up, output signal can directly connect with microcontroller io. Can detect fire or wavelength in 760 ~ 1100 nm nano within the scope of the light source. Detection angle about 60 degrees, the flame spectrum especially sensitive. The flame of the most sensitive sensors flame, the regular light is also a response, generally used for fire alarm purposes. Uses:
