# Example for `sgp41` and `aht20` driver ## What it does The example configures a `aht20` and a `sgp41` devices. It shows temperature, humidity, human-readable `VOC` and human-readable `NOX` level in a loop. ## Wiring Connect `SCL` and `SDA` pins to the following pins with appropriate pull-up resistors. | Name | Description | Defaults | | ------------------------------- | --------------------- | -------------------------------------------------------------------------------- | | `CONFIG_EXAMPLE_I2C_MASTER_SCL` | GPIO number for `SCL` | "5" for `esp8266`, "6" for `esp32c3`, "19" for `esp32`, `esp32s2`, and `esp32s3` | | `CONFIG_EXAMPLE_I2C_MASTER_SDA` | GPIO number for `SDA` | "4" for `esp8266`, "5" for `esp32c3`, "18" for `esp32`, `esp32s2`, and `esp32s3` |
