VS 1838 B Infra Red Receiver Experiment

This is my first experiment of Infra Red , I'm using VS 1838 B because this is the most low price of other similar components. I experiment on how to send and receive data via Infra Red.

This is physical form of VS 1838 B

This is pinout of VS 1838 B

So the first measurung and observation experiment produce some result, when there is a signal light to the sensor , so the voltage at the output ( pin 1 ) arround 4.5 volts . But if there is no signal light , the voltage arround 3.7 volts.

After i read some article on internet, i knew that this measuring method is WRONG..... and then i using Oscilloscope to measure this device. I use Air Conditioner and Television remote control to send signal to IR Receiver.

And then, after setting some parameter adjustmen on Osciloscope front panel, I try to send signal using Television remote control.

Then i try to send signal using Air conditioner remote control. So data signal is certainly different.

So, this is video my simple experiment about infrared receiver using VS 1838 B. And i plan to combine multiple infrared receiver using AND Gate IC.
