Sensor uses HX1838, high sensitivity.
Operating voltage 5V.
Output form: Digital output.
VCC: 3.3V-5V external voltage (can be directly connected to the 5v micro-controller and 3.3v micro-controller).
GND: external GND.
IN: external micro-controller I/O port, I/O port has been designed 10K pull-up resistor.
Kit theory test distance of about 5-8 meters, but the practical
application depends on the ambient factors you use, as well as the
middle barrier (such as diaphragm, glass, obstructions or other material
blocking), receiving head with HX1838 with power work instructions
lights, receive 38K frequency any remote coding data.
