Grab'eM IR REMOTE CONTROL Transmitter Receiver/Decoder KIT (Multicolor)

microcontroller interface development board learning experiment, HX1838 remote control module, diy electronic experiment kit! Test Kit theory distance of about 5-8 meters, but the actual application you use depends on the environmental factors around the time of the intermediate and barrier (such as a diaphragm, glass, or other obstructions blocking material), receiver using HX1838, with power work instructions lamps, can receive any 38K frequency remote control code data! Features: • sensor uses HX1838, high sensitivity • Operating voltage: 5V • Output Type: Digital Output • VCC: 3.3V-5V external voltage (can be directly connected to the 5v and 3.3v microcontroller MCU) • GND: connect to GND/negative of the circuit. • IN: external MCU I / O ports, I / O port has been designed pull-up resistor 10K
