I need to connect esp32 with sensor

Community General Info - Guidance
#1

Hii ,
I connect ESP WROVER32 connect with Seeed sensor ,so i used this github:-GitHub - limengdu/Seeed-Studio-MR24FDB1-Sensor: Seeed_24GHz_mmWave_Radar_Sensor
but I could not getting data of sensor using this code , Please suggest me any documentation and code
I will connect the arduino with uart pin TX and RX

#2

You can follow this wiki:

but the mcu used in wiki is xiao esp32c3, not ESP WROVER32

#3

Any other ESP board is working expect XAIO ESP32C3

Hi there,
Of course you can make it work if you use the correct pins…

@PJ_Glasso Hii
Actually we should interfacing the pin of GPIO 16 RX or 17 TX pin but the esp32 Wroom 32 e is reset self

#6

Please give any suggestion or documentation
I found this error while geeting the data with esp32wroom

Hi there,
Yes the Output is indicating, a WatchDogTimer caused System Reset. probably because the SPI is jammed and didn’t respond.
Post the code, use the code tags we can look and make suggestions.

@PJ_Glasso I used this library -GitHub - limengdu/Seeed-Studio-MR24FDB1-Sensor: Seeed_24GHz_mmWave_Radar_Sensor
and connect with sensor and this code I am using
#include <falldetectionradar.h>

FallDetectionRadar radar;

void setup()
{
radar.SerialInit();
Serial.begin(9600);
delay(1500);
Serial.println(“Readly”);
}

void loop()
{
radar.recvRadarBytes(); //Receive radar data and start processing
if (radar.newData == true) { //The data is received and transferred to the new list dataMsg[]
byte dataMsg[radar.dataLen+1] = {0x00};
dataMsg[0] = 0x55; //Add the header frame as the first element of the array
for (byte n = 0; n < radar.dataLen; n++)dataMsg[n+1] = radar.Msg[n]; //Frame-by-frame transfer
radar.newData = false; //A complete set of data frames is saved

//radar.ShowData(dataMsg);                 //Serial port prints a set of received data frames
radar.Situation_judgment(dataMsg);         //Use radar built-in algorithm to output human motion status

}
