IR Speed Sensor

This IR Speed Sensor is used to count RPM or detect objects passing through. You can use it with a disc encoder to make an RPM counter. There is an on board LED that will show the trigger status of the sensor. When the sensor is blocked, the digital output will become high, and LED will turn off, vice versa when sensor is not blocked, digital output will be low and LED will turn on.There is an onboard comparator IC to ensure signal is clean.

Specifications:

• Operating voltage: 3.3-5.5v
• Use the LM393 wide voltage comparer
• Output form: Digital switching output (0 and 1)
• Dimensions: Approx. 32 x 14 x 7 mm
