The sensor uses HX1838 and high sensitivity.
Operating voltage: 5 V
Output Format: Digital Output
VCC: 3.3V-5V external voltage (can be directly connected to 5v microcontroller and 3.3v microcontroller)
GND: External GND
IN: External microcontroller I/O port, I/O port is designed as a 10K pull-up resistor. The test distance of the kit theory is about 5-8 meters, but the actual application depends on the surrounding factors to use, and the intermediate barriers (such as blocking diaphragm, glass, obstacles, and other materials), and the reception head with powerwork in HX1838 Receive a remote coding data with a 38K frequency.
Package includes:
3 x HX1838 VS1838 IFR Infrared Reception Head
3 x IR wireless remote control
3 x Dupont Lines
