Output Channel: 1
Power Supply: 3.3/5V
Built in a potentiometer for sensitivity control.
Onboard signal output indication, output effective signal is high, at the same time the indicator light up, the output signal can directly connect to microcontroller IO.
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.
Dual output mode, analog output more accurate
A fixed bolt hole for easy installation
With power indicator (red) and digital switching output indicator (green)
Having LM393 comparator chip, stable.
Operating Voltage: 3.3V~5V
Main chip: LM393, Electret condenser microphone
Working voltage: DC 3.3-5V
Induction distance is 0.5M
Signal output Indication
Single channel signal output
The output effective signal is low level.
