1. 连接LCD: PCF8574T模块4pin(Gnd, Vcc, SDA i2c数据, SCL i2c时钟) 连接至Arduino接口 Gnd -> Gnd, Vcc -> Vcc, SDA -> A4, SDL -> A5 2. 连接YL-47 DHT11: Gnd -> Gnd, Vcc -> Vcc, Data-> D4 Library 除了1602需要的库以外, 需要安装两个自带的库: DHT Sensor Library by Adafruit, ...

幸运的是，将DHT11或DHT22传感器连接到Arduino很简单。它们使用2.54mm间距的排针，因此您可以轻松地将...
5。接下来是LCD显示数据: LCD显示模块led_dht11.pyd 参考了git上的Adafruit_CharLCD()代码,主要的功能是读取dht11的执行结果进行lcd显示 #!/usr/bin/python # # based on code from lrvick and LiquidCrystal # lrvic – https://github.com/lrvick/raspi-hd44780/blob/master/hd44780.py ...
