BME280 Temperature, Humidity and Pressure Sensor
The ESP32-S3 TFT Feather comes with an unpopulated space for a BME280
Temperature, Humidity and Barometric Pressure Sensor.
The sensor connects over I2C (at address 0x77), and provides immediate ambient
weather sensing. It is rated for measuring humidity with ±3% accuracy, barometric
pressure with ±1 hPa absolute accuracy, and temperature with ±1.0°C accuracy.
Because pressure changes with altitude, and the pressure measurements are so
good, you can also use it as an altimeter with ±1 meter or better accuracy!
There is a power pin that must be pulled high for the sensor to work. This is done
automatically by CircuitPython and Arduino. The pin is available in CircuitPython and
in Arduino as TFT_I2C_POWER .
There is currently no BME280 sensor shipped on the ESP32-S3 TFT Feather -
only a space for it!
If you run into I2C or TFT power issues on Arduino, ensure you are using the
latest Espressif board support package. If you are still having issues, you may
need to manually pull the pin HIGH in your code.
