ESP32内部空气质量测量套件用户指南说明书 Indoor Air Quality with ESP32 Board # K0068 User guide Rev 1.0 Apr 2017
This tutorial shows how to use the DHT11 or DHT22 temperature and humidity sensors with the ESP32 and ESP8266 development boards using MicroPython firmware.
print("Error: failed to read sensor") else: print("Temperature: ", temperature) print("Humidity: ", humidity) 这段代码首先导入了必要的库,然后定义了DHT11设备所连接的引脚(在这个例子中是4号引脚),然后初始化了DHT11库。接着,它调用read()方法来读取温度和湿度数据,然后等待一秒以获取稳定的数据。最...
Tutorial 1: DHT22 sensor In this tutorial, we'll use the DHT22 temperature/humidity sensor and send measurements to the Google IoT Core. MountDHT22 sensorto the breadboard: Use the black jumper wire to connect GND pin to the HUZZAH32 GND pin ...
& Humidity Sensor. Since the air we breathe out is moist and warmer than surrounding, you can see a spike in values in one of the pictures. The chart also shows a sudden increase in Temperature & Humidity as well as some drop in Pressure since Temperature and Pressure are inversely ...
Although it’s a basic design, it is pretty accurate, thanks to an Adafruit AHT20 temperature and humidity sensor. This is an I2C device that has an accuracy of 1% for temperature and 3% for humidity. We’ll monitor the temperature and humidity using a dashboard. Connecting the Arduino ...
