Troubles with my Sensor Output

Other Hardware Sensors
1

Dear Arduino Community!

This is my first Post on this forum. I don't know if I had chosen the right Topic.

My Problem:
I don't get all meassurements from my sensor (with the right library not one)

Hardware used:
-Arduino IDE 2.0.1
-Windows 10 22H2
-ESP8266mod (Wemos D1 Mini)
-SSC 811 HDC1080 Sensor

Librarys i used:
https://github.com/bfaliszek/CJMCU-8118_InfluxDB

The senor works in a SSC811 Liberary, but only for CO2 and Air Preassure. My senor also has an HDC1080, which meassures the humidity and the temperature. The only Video i found out there regarding my setup was this one:

Pinset of my board:

My wireing:
linkhttps://ibb.co/VQyGs4X

Connections:
VCC -> 3V3
GND -> GND
SCL -> D1
SDA -> D2
WAK -> D3

Code:

#include <Wire.h>
#include "Adafruit_CCS811.h"
#include "ClosedCube_HDC1080.h"

ClosedCube_HDC1080 hdc1080;
Adafruit_CCS811 ccs;

void setup() {
  Serial.begin(9600);

  Serial.println("CCS811 test");

  if(!ccs.begin()){
    Serial.println("Failed to start sensor! Please check your wiring.");
    while(1);
  }

  // Wait for the sensor to be ready
  while(!ccs.available());
  hdc1080.begin(0x40);
}

void loop() {
  if(ccs.available()){
    if(!ccs.readData()){
      Serial.print("CO2: ");
      Serial.println(ccs.geteCO2());
      Serial.print("ppm, TVOC: ");
      Serial.println(ccs.getTVOC());
    }
    else{
      Serial.println("ERROR!");
      while(1);
    }
  }
  Serial.print("T=");
	Serial.print(hdc1080.readTemperature());
	Serial.print("C, RH=");
	Serial.print(hdc1080.readHumidity());
	Serial.println("%");
  delay(1000);
}

Serial Monitor:

Failed to start sensor! Please check your wiring

I would be so happy if someone could help out here! I stayed awake until 4am to fix that haha :frowning:

Thank you guys!

it is probably worth running the ESP8266 I2C scanner to see what it finds
could you upload a schematic of the wiring?
have a readthru the HDC1080 data sheet
this may also help Arduino Uno and HDC1080 humidity and temperature sensor

Hey horace!

Thank you for your answer and your help. I manged to get the sensor perfectly fine running on an ESP32 instead of an ESP6822. I'll have an look on the IC2 Scanner!
