ESP8266:将SDA引脚连接到GPIO 4(D2),将SCL引脚连接到GPIO 5(D1) 原文章地址:https://randomnerdtutorials.com/esp32-esp8266-dht-temperature-and-humidity-oled-display/
Let’s walk through the code. This example tests LM35 temperature sensors. The code is used to read the temperature and print on the serial terminal. You can build your project upon this code further to activate lights and control the relay modules based on the value read by the temperature...
ESP32-S3, ESP32-C3, and ESP32-C2. This onboard temperature sensor is usually used to monitor the core temperature changes of the chip, whereby possessing a temperature range of -40°C to 125°C. It features an 8-bit Sigma-Delta ADC and a temperature offset DAC. The temperature sensor ...

为了显示º符号,我们使用Code Page 437字体。为此,您需要将cp437设置为true,如下所示: 然后,使用write()方法显示您选择的字符。º符号对应于字符167。 使用类似的方法来显示湿度 不要忘记,您需要在最后调用display.display(),这样您才可以在OLED上实际显示某些内容。
