Good sensitivity
Detects candle flame easily from a foot away. Wish the wires were longer.
5 FAQ
Q: What is the power consumption?
A: It consumes approximately 20mA during operation, suitable for most microcontroller pins.
Q: Does it come with jumper wires?
A: No, jumper wires are sold separately. The module has header pins ready for connection.
Q: Is this compatible with Raspberry Pi?
A: Yes, it works with 3.3V logic systems like the Raspberry Pi GPIO.
Q: Can this detect sunlight?
A: It is sensitive to IR light, so direct sunlight may trigger false positives. Use indoors or shielded.
Q: What is the difference between 3-wire and 4-wire?
A: 4-wire includes both analog and digital output pins, while 3-wire typically offers one or the other depending on configuration.
