BME280からデータ取得

モジュールの設置が完了したので実際にデータを取ってみます!

1つメのモジュールでは以下

from machine import I2C,Pin
from BME280 import *
from utime import sleep
p21 = Pin(21,Pin.IN,Pin.PULL_UP)
p22 = Pin(22,Pin.IN,Pin.PULL_UP)
i2c =I2C(scl=Pin(22), sda=Pin(21))
bme280 = BME280(i2c=i2c)
while True:
    print(bme280.values)
    sleep(1)

これは1秒ごとにBME280から温度,湿度,気圧を取得する.

実行結果

('27.14C', '984.20hPa', '48.77%')
('27.14C', '984.19hPa', '48.79%')
('27.14C', '984.16hPa', '48.81%')
('27.13C', '984.16hPa', '48.90%')
('27.13C', '984.17hPa', '48.92%')
('27.14C', '984.22hPa', '48.89%')
('27.14C', '984.20hPa', '48.98%')

重要な点!!

  • ピンのプルアップ
    ピンをプルアップしなければI2Cは使うことができない.
    ※SCL/SDAの 2つの信号配線は、 それぞれ、 電源に、 抵抗を介してプルアップする必要がある.
#プルアップの方法

from machine import Pin
p21 = Pin(21,Pin.IN,Pin.PULL_UP) # 21ピンをプルアップ
p22 = Pin(22,Pin.IN,Pin.PULL_UP) # 22ピンをプルアップ
  • SCL,SDAのピン設定
    SCL,SDAで利用するピンを設定しなければならない.
    ESP32ではピン配置から,以下のように決まっている

再喝

定数 PIN
SDA D21
SLI(SCL) D22
from machine import I2C
i2c =I2C(scl=Pin(22), sda=Pin(21))

2つメのモジュールでは以下

from machine import Pin, I2C
from time import sleep
import BME280

p21 = Pin(21,Pin.IN,Pin.PULL_UP)
p22 = Pin(22,Pin.IN,Pin.PULL_UP)

i2c = I2C(scl=Pin(22), sda=Pin(21), freq=10000)

while True:
  bme = BME280.BME280(i2c=i2c)
  temp = bme.temperature
  hum = bme.humidity
  pres = bme.pressure
  # uncomment for temperature in Fahrenheit
  #temp = (bme.read_temperature()/100) * (9/5) + 32
  #temp = str(round(temp, 2)) + 'F'
  print('Temperature: ', temp)
  print('Humidity: ', hum)
  print('Pressure: ', pres)
  sleep(5)

実行結果

emperature:  25.18C
Humidity:  48.23%
Pressure:  980.50hPa

Temperature:  25.18C
Humidity:  48.35%
Pressure:  980.56hPa

Temperature:  25.19C
Humidity:  48.52%
Pressure:  980.48hPa

Temperature:  25.20C
Humidity:  48.52%
Pressure:  980.45hPa

無事温度・湿度・気圧を取得できたら成功です!
お疲れ様でした
