Pin connections from Nova to a BME280:

  • Nova IO0 to SDI
  • Nova IO2 to SCK
  • Nova 3V3 to VIN
  • Nova GND to GND

Example code

This example uses Adafruit’s busio package to create an I2C object.

import time
import board
import busio
import adafruit_bme280

# Create library object using our Bus I2C port
i2c = busio.I2C(board.SCL, board.SDA)
bme280 = adafruit_bme280.Adafruit_BME280_I2C(i2c)

# change this to match the location's pressure (hPa) at sea level
bme280.sea_level_pressure = 1013.25

while True:
  print("\nTemperature: %0.1f C" % bme280.temperature)
  print("Humidity: %0.1f %%" % bme280.humidity)
  print("Pressure: %0.1f hPa" % bme280.pressure)
  print("Altitude = %0.2f meters" % bme280.altitude)
