What is IR in microcontroller?
IR Receiver. The IR Receiver device consists of an infrared receiver IC combined with the XC822MT microcontroller. Next to the power supply pins (2.9V to 5.5V), just one additional pin is required for the infrared receiver IC. The remaining 12 IOs can be used for custom application signals.

How is a microcontroller used in a remote control?
The input signal from switches is processed by the microcontroller, encoded by the encoder, modulated and transmitted by the transmitter. At the receiver, the modulated signal is demodulated by the IR receiver, decoded by the decoder and processed by the microcontroller to control the output loads.
How can I use IR sensor without Arduino?
take a look at transistor and note which pin is base, emitter and collector pin. Step-3: connect emiiter of transistor to ground or negative rail of breadboard where negative terminal of battery is connected. step-4:Connect Vcc pin of IR sensor to positive Rail ,Gnd pin to negative rail of breadboard.
How do IR sensors work?
Active infrared sensors both emit and detect infrared radiation. Active IR sensors have two parts: a light emitting diode (LED) and a receiver. When an object comes close to the sensor, the infrared light from the LED reflects off of the object and is detected by the receiver.

Why is infrared used in TV remotes?
TV remote controls work in a similar way but using a type of light called infrared (or IR for short). The remote control has an LED light in it which flashes really quickly to emit a message which is then picked up by the TV. The remote is called the transmitter, and the TV is called the receiver.
What is the frequency of IR sensor?
Infrared (IR) has wavelengths λ between 780 nm and 1 mm, which corresponds to a frequency range from 300 GHz to 400 THz.
Which wave is used in TV remote?
infrared light waves
A remote control uses light waves just beyond the visible spectrum of light—infrared light waves—to change channels on your TV.
