A sensor that detects IR signals emitted by devices like remote controls. It is used for remote control applications.
In other words, it detects IR signals emitted by devices like remote controls.
Description:
This device detects patterns of infrared light created by a remote control or wireless communication.
How It Works:
Used with an IR remote, an IR sensor detects patterns of light for wireless communication.
Connect It:
This device has three wire leads, and is often connected to the digital input of a microcontroller. Power the device by connecting the Power pin to the 5V and GND to ground. The Out pin is connected to a digital input on an Arduino.
How It Is Used:
Select the device to edit its name. It will receive the signal from any IR Remote in your circuit.
Get Started:
Drag the starter circuit below into your design for a working example of how to use this part.
More About IR Sensor:
To add an IR Sensor in Tinkercad, search for "IR Sensor" in the component library, drag it onto your breadboard, and connect its terminals with wires to other components in your circuit. You can then click on the IR Sensor to set its name for easy identification.
IR sensors primarily rely on an IR Emitter (typically an IR LED) and an IR Receiver (like a Photodiode or Phototransistor) as their core components. The emitter transmits infrared radiation, often with a wavelength in the Near-Infrared range (e.g., 850 nm to 950 nm). The receiver then detects the radiation, converting the measured Irradiance or Radiant Power (often in Watts per square meter (W/m2) or simply Watts (W)) into an electrical signal. Key specifications include the Detection Range, which for active, short-range proximity modules might be up to 20 cm or 5 meters for proximity sensors, while Passive Infrared (PIR) motion sensors can reach 5 to 12 meters. The Power Rating or Power Consumption is typically low, with many simple modules drawing less than 25 mA at supply voltages like 3.3 V or 5 V. Other crucial specifications include the Spectral Responsivity of the receiver (measured in Amperes per Watt (A/W)), which indicates its efficiency, and Response Time (often in nanoseconds (ns) to microseconds (μs) for photodiodes, or slower for phototransistors), which dictates the maximum signal frequency or switching speed.
