Hello good weekends, I am not getting data from the esp8266-01 and si7021 module I am working on, I would be glad if you help?
The purpose of this project is to send temperature and humidity information from esp8266 to the web. Si7021 is a temperature and humidity sensor. Si7021 datasheet * "https://cdn.sparkfun.com/datasheets/Sensors/Weather/Si7021.pdf"

#include <WiFiClient.h>
//Sensor

#include <Wire.h>
float humidity = 0;
float tempf = 0;
Weather sensor;
