Photo resistors are light sensitive resistors whose resistance decreases as the intensity of light they are exposed to increases.
The Vibration module based on the vibration sensor SW-420 and Comparator LM393 to detect if there is any vibration that beyond the threshold. The threshold can be adjusted by the on-board potentiometer.
The flame sensor can be used to detect fire or other wavelength at 760 nm ~ 1100 nm light. The Flame sensor is very sensitive to the flame and can respond to the regular light, it’s generally used for fire alarm purposes.
