Please, help to figure out the pinout of microwave motion sensor FC1816.
The seller "doesn't understand" what it is required on queries to provide the pinout for the module. The module is the smallest microwave motion sensor I found, so it's very welcomed to run it.
I followed traces to find the function of 4 pins of 5. Please, help me to understand last pin. UPD: This question solved. Other question arose below...
From left to right:
- Pin 1: Out, connected to pin 2 of BISS0001.
- Pin 2: Vcc, connected to pin 8 of BISS0001.
- Pin 3: Enable, connected to pin 9 of BISS0001. Short it to GND should run the BISS.
- Pin 4: Gnd, connected to pin 7 of BISS0001.
- Pin 5: UPD: Vcc of microwave generator.
I have tried to connect both Vcc together to +5V, Enable to Vcc via 2k resistor (pullup), ground as regular. The out gives always logical 1.
What voltage should be supplied? BISS0001 supports up to 5V.
