Technical summary
Description: Chip
: HX1838, high sensitivity.
Operating voltage 5V
Output form: Digital output.
VCC: external 3.3V-5V voltage (can be connected directly to a 5V microcontroller and a 3.3V microcontroller).
GND: external GND.
IN: I/O port of the external microcontroller, the I/O port is designed for a 10K pull-up resistor.
Theoretical test distance of the kit is about 5 to 8 meters, but practical application depends on the environmental factors where you use it, as well as on the central barrier (such as a membrane, glass, obstacles or other material blockages); the receiver head with HX1838 with electrical working instructions receives all remote coding data at a frequency of 38K.
