Infrared Transmitter IR Receiver Module w/ 38K Carrier for Arduino
This is based on NE555 infrared transmitter module. 38KHz carrier circuit board produced by the NE555£¬ no MCU's PWM pins to reduce the corresponding code£¬ reducing the burden on the MCU. SIG module pin is high£¬ the module will send an infrared signal of 38KHz£¬ SIG pin is low£¬ the module will stop sending infrared signals£¬ the use of very simple£¬ so ordinary single-chip infrared remote control can also be easily produced items . Features: - Compatibility: Arduino UNO R3 / Arduino Mega2560 and other microcontroller board - Operating voltage: 4.5 - 5.5VDC - Operating Current: 50mAh (max) - Emission angle: 45 degrees - SIG pin current: High level 0.4mA (max)£¬ low level 1.4mA (max) - You can manually adjust the direction of the launch tube according to the actual application requirements - Great for infrared remote control projects Infrared Receiver module: This is infrared receiver module based on integrated infrared receiver head. It can receive the modulated infrared signal of 38KHz that is sent by the IR transmitter module and demodulate it into logic level£¬ ie£¬ when it gets the modulated infrared signal£¬ it outputs one negative pulse and returns to normalcy (High level). The infrared receiver module and transmitter module can complete the infrared remote control with the codec program. - Operating voltage: 3.0 - 5.5VDC - Operating Current: 2mAh (max) - Receiving angle: 90 degrees
