IR Remote Control Module+IR Telecontrol+Receiver
- VDC external 3.3V-5V (connects directly to 5V MCU and 3.3V chip)
- external GND GND
- In the external I / O port of the microcontroller, the I / O port is designed with 10K pull-up resistor
- 8 meters theoretical test kit, but the surrounding environmental factors depend on when you use a valid application and an intermediate barrier (eg diaphragm, glass, barrier or other material).
- The receiving head uses the HX1838 with a power LED and can receive any 38K frequency of remotely encoded data!
- the sensor uses HX1838, high sensitivity
- 5V operating voltage
- output: digital output
