TSOP-1738 IR Sensor (3-pin)
Product Details
Key Features:-
IR Receiver: The TSOP-1738 is designed as an IR receiver module. It receives infrared signals typically emitted by remote controls or other IR transmitters.
Frequency Specific: This sensor is designed to work with a specific carrier frequency, often 38 kHz, which is a common carrier frequency used in many remote controls. It is essential to ensure that the carrier frequency of the IR transmitter matches the sensor's frequency for proper operation.
Demodulation: The TSOP-1738 includes demodulation circuitry that filters out the carrier frequency, leaving only the modulated data signal. This makes it easier to work with the received data.
Digital Output: The sensor provides a digital output that indicates whether it is receiving an IR signal. When it receives a valid signal, the output typically goes LOW.
Sensitivity: These sensors are highly sensitive to infrared signals, which allows them to detect remote control signals from a reasonable distance.
