How to See Infrared Light: 10 Steps (with Pictures) - wikiHow

· IR has a very subtle rolling wave, and UV has an extreme zigzag pattern to their wavelengths. Have you seen on TV when a car is in motion and the tires go forward, then seem to stand still before appearing to spin backwards? This is due to the frame rate of the film. Your device, unless you have super high DPI and refresh rate, is going to show it as bluish-purple. Top-end devices display it ...

How to Fix a Broken TV IR Sensor | Techwalla

· To test this, open your phone's camera app, point the remote's IR emitter – located behind the shiny plastic on the end of the remote you point at the TV – at the camera lens and press and hold a button. If the remote is working, you'll be able to see a light (which you can't normally see with the naked eye) on your camera's viewfinder screen. If there's no light, you may need a new remote.

1. Confirm the pin-out from the data sheet. Two pins will be DC power in; a voltage between + and +5v, the other ground. The third pin is output, which may be floating, or may have an internal high-value pull-up resistor to the positive DC supply pin. Incorrect application of power to Vdd and ground pins can/will easily destroy the device.
