Troubleshooting BME280 Sensor Data Reading Issue on Raspberry Pi Pico with MicroPython

Hello, I am trying to interface a BME280 sensor with a Raspberry Pi Pico using MicroPython over I2C to monitor environmental conditions such as temperature, humidity, and pressure. However, I am encountering an issue with reading the sensor data, I have referred to the BME280 sensor documentation and the MicroPython library documentation to confirm the correct method for reading sensor data, I have examined the `bme280` library code to verify the methods available for reading data from the sensor, I reinstalled the `bme280` library to ensure it was correctly installed, I ran a simple I2C scan script to ensure that the BME280 sensor is properly connected and detected by the Raspberry Pi Pico.

i2c = I2C(0, scl=Pin(17), sda=Pin(16), freq=100000)
devices = i2c.scan()
print("I2C devices found:", devices)

But still getting the error

AttributeError: 'BME280' object has no attribute 'read_compensated_data'

This is my code

from machine import I2C, Pin
import time
import bme280

# Initialize I2C
i2c = I2C(0, scl=Pin(17), sda=Pin(16), freq=100000)

# Create BME280 object
bme = bme280.BME280(i2c=i2c)

while True:
    temperature, pressure, humidity = bme.read_compensated_data()
    print(f"Temperature: {temperature/100:.2f} °C")
    print(f"Pressure: {pressure/256:.2f} hPa")
    print(f"Humidity: {humidity/1024:.2f} %")
    time.sleep(1)

@Middleware & OS

  1. RED HAT#0000

    Hi @enthernetcode It looks like the method `read_compensated_data` does not exist in the `bme280` library you are using. You might want to check the documentation or the source code of the library to find the correct method for reading data from the sensor

  2. wafa_ath#0000

    Hello @enthernetcode

    `read_compensated_data()` method doesn’t exist in your BME280 library. Try adding this:

    “`
    while True:
    print(f”Temperature: {bme.temperature:.2f} °C”)
    print(f”Pressure: {bme.pressure:.2f} hPa”)
    print(f”Humidity: {bme.humidity:.2f} %”)
    time.sleep(1)
    “`
    If this doesn’t work, check your BME280 library’s version

  3. Enthernet Code#0000

    okay would do
