使用DHT22+ESP8266+2个OLED显示屏,接入到Blynk实现在手机端和设备通过一个屏幕端试试显示温湿度的同时,加入NTP自动校时使第二个屏幕显示时间和日期.这里使用的外壳是3D打印当然,你也可以自己做一个外壳,模型的链接下面回放出,有需要的可以去淘宝找店家打印一个.由于我的外壳没有空间加按钮开关了,所以也就没有整合WIFImanager的功能,需要的可以看看我上一编制作气象仪的文章.

基于Blynk+Arduino制作双显示屏实时温度计

显示温湿度
NTP自动校准时间
手机端实时显示温湿度数据
手机端实时显示网络信息
手机端使用按钮控制屏幕的开启/关闭
手机端设置屏幕的定时开启/关闭
OTA更新固件

ESP8266 – X 1(D1mini/NodeMCU也行)
DHT22温湿度传感器 – X 1(也可以是DHT11,可选已加电阻的,不带电阻的需要自己加一个10K的电阻)
0.96’OLED屏幕 – X 2(SSD1306主控)
3D打印机 – X 1(可选,外壳模型点这里下载)

如果你的DHT22是没有自带电阻的就必须加个10kΩ电阻,电阻一端接到单片机的3.3,另一端接到DHT的OUT,不然读数及有可能不正常
DHT22/OLED都可以接到5V,具体按你到手的为准,市面上多数支持3.3-5V

设备				引脚
ESP8266	3.3	GND	D2	D3	D4	D5	D6
DHT22	Vcc	GND	OUT
OLED1	Vcc	GND		SDA	SCL
OLED2	Vcc	GND				SDA	SCL
10K电阻	s1	s2
