M5CloudでDHT12センサを扱うサンプルスクリプト。一定時間ごとに温度と湿度を液晶画面に表示する。DHT12用ライブラリ(dht12.py)が必要: https://github.com/m5stack/M5Cloud/blob/master/lib/dht12.py

main.py

from m5stack import lcd
import dht12
import utime

sensor = dht12.DHT12()
sensor.measure()

temperature = sensor.temperature()
humidity = sensor.humidity()

lcd.clear()
lcd.setCursor(0, 0)

while True:
    lcd.println('Temperature: {:.1f} `C  Humidity: {:.1f} %'.format(temperature, humidity))
    utime.sleep(3)
