LM393 Dual Voltage Comparator

Two comparators that switch their output when one input rises above the other, giving a clean digital decision from an analogue signal. This is the chip inside most sensor modules with an adjustable threshold potentiometer - the flame, sound, LDR and line sensors all use one. The open collector output can pull to a different voltage than the chip's own supply, which is what makes it so flexible for interfacing.
