在这个项目中,我开发了一个Arduino库来读取 DHT11 湿度和温度传感器生成的数据,并使用 AZDeliveryESP8266ESP-12F NodeMCULua Amica V2 将其连续发送到 ThingSpeak 云服务。 有许多库可以用来读取 DHT11传感器数据。那么,为什么要重新发明轮子呢?只是为了了解事物的运作方式并可能改进它们的乐趣。

It could be dodgy, a lose connection, or a mistake in the circuit. Also, just want to check that you updated the code to reference DHT11 and not DHT22? Reply Adam on October 20, 2022 at 4:02 am After replacing a DHT22 that had gone bad by a brandnew one I got values like ...
DHT11 interfacing with Arduino Uno DHT11 interfacing with pic microcontroller DHT Asynchronous Web Server ESP32 First, let’s discuss DHT11/DHT22 Server Sent Events Asynchronous web server. Asynchronous Web Server Overview The client starts the server-sent events connection with ESP32 server as an ...
All examples provided use Arduino UNO's digital pin 2 as the default connection to the DHT11 sensor's data pin. Modify this in the code if using a different pin.Read Humidity This example demonstrates how to simply read the humidity value from the DHT11 sensor and display it on the ...
The DHT11 measures temperature with a surface mountedNTC temperature sensor(thermistor) built into the unit. To learn more about how thermistors work and how to use them on the Arduino, check out ourArduino Thermistor Temperature Sensor Tutorial. ...
