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)
time.sleep(2)
