Doppler Radar Motion Sensor MW2401TR11 - data output protocol info?

Hi,
I am trying the arduino sample code at below link:

I would like to under what’s the meaning of begin_code, state_code, gear_code, delay_code, and check_code. Do you have the datasheet to explain the protocol of data output?

Also, can this senor output the distance info? Or how can we calculate the moving object distance?

Regards,
Elisa.

Sorry, the link above is wrong.This is the correct Wiki link.I hope this Wiki can help you.

Hello,
That is the same link I have read. I don’t see any difference.


Also, I found the analog output value keep at [768-776 ] no matter there is a moving object in front or not. I am using arduino mega board, connection as attached image. Below is my sketch:

int MW_out = A0;

void setup() {
Serial.begin(9600);
Serial1.begin(115200);
delay(2000);
Serial.println(“start”);
}

void loop() {
Serial.print(analogRead(MW_out));
delay(2000);
}

May I know what went wrong? Also may I have below info:

  1. data output protocol information
  2. distance calculation info

Thank you very much.
Elisa.
