Brand New and high quality.
The sensor uses hx1838, high sensitivity.
Test distance of the theory of the kit of about 5-8 meters, but the practical application depends on the environmental factors used, as well as the average barrier (such as the diaphragm, glass, obstacles or other material blockage), receiving the head with hx1838 with power work instruction lights, receive 38 K Frequency of any remote encoding data.
Operating voltage: 5 V
Output form: Digital output
VCC: 3.3V-5V external voltage (can be directly connected to the 5v microcontroller and 3.3v microcontroller)
IN: external microcontroller I/O port, I/O port has been designed 10K pull-up resistor
