1. Sensor uses HX1838, high sensitivity.
2. Operating voltage 5V.
3. Output form: Digital output.
4. VCC: 3.3V-5V external voltage (can be directly connected to the 5v microcontroller and 3.3v microcontroller).
5. GND: external GND.
6. IN: external microcontroller I/O port, I/O port has been designed 10K pull-up resistor.
7. 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.
