Carrier Frequency 38KHZ Far Infrared Communication Module, Far Infrared to TTL Module GND TXD RXD VCC Transceiver Pair Tube

Carrier Frequency 38KHZ Far Infrared Communication Module, Far Infrared to TTL Module GND TXD RXD VCC Transceiver Pair Tube Module introduction: This communication module integrates an infrared transmitter and an infrared receiver. The transmitter is equipped with a 38KHZ generator, which can use two modules to realize infrared communication. Wide working voltage, small size and long communication distance. This module can only work under the carrier frequency of 38KHZ.
Features: Wide
working voltage: 2.7V ~ 5.5V
Infrared wavelength of receiving/sending: 940nm
Receiving/transmitting carrier frequency: 38KHZ
Transceiver mode: dual-module remote communication
Module interface pin function table: VCC-- module power supply GND--module ground RXD-- infrared receiver TXD-- infrared transmitter Receive/transmit with 38KHZ carrier signal The transmitter comes with a 38KHZ carrier generator
Receiving/transmitting carrier frequency 38KHZ: a. The receiver tube receives the 38KHZ carrier frequency signal and decodes it, namely receiving-amplifying-detecting-shaping. The RXD port is the decoded signal. b. The transmitting signal is input from the TXD of this module, encoded by the 38KHZ carrier generator on the module, and then transmitted by the transmitting tube.
