Help needed ASAP

InfluxDB 2 Dashboards
1

Hi
I am building an indoor air quality monitoring project so I have a code,can someone help me to edit the code and send data to influx db then grafana for creating dashboard
I am just a student and building a college project ,so pls if someone know how to edit the code to update the sensor data to influx db pls help me​:pray::pray::pray:
Components i am using
0.96 OLED display
Bme280
C03 sensor
ESP32 board

Pls help me :pray:

Hello @Thakur_Ashish,
Welcome!
Have you seen the following resources:
