使用ESP8266 内核为 Arduino 读取传感器数据 我们有几种方法来读取数据并处理 DHT11 使用的专有单线通信协议: 盲循环:等待固定的时间,并假设 I/O 将在该固定延迟过去之前完成。此方法不适合我们读取传感器数据,因为 0s 和 1s 时序不同,您可能会失去同步,但我们将使用它来启动信号到 DHT,因为这是使 DHT11 从...

Need help getting started with your DHT11 and DHT22? We’ve got you! Here’s a tutorial on how to get started together with the Arduino together with our DHT modules! What you’ll need: Arduino UNO/Seeeduino V4.2 Grove Base Shield(Optional, for easy connection) ...
it's easy to integrate into your existing projects without taking up too much space. The ESP8266 does not have Bluetooth, but it does offer a reliable WiFi connection, ensuring that your smart home devices can be controlled remotely. Whether you're a seasoned developer or a DIY enthusiast, ...
We save the file with CTRL + O and exit the editor with CTRL + X. Then we execute our code: sudo python dht_example.py Earlier version There is also another repository from Adafruit, which should no longer be used. For the sake of completeness, I’ll show it here anyway (you can ...
1 2 Re: WDT Reset using DHT11#84534 Bylolo-Tue Nov 12, 2019 6:16 pm I personally got a "similar" issue having a reset after 8sec when readin values from dht 22 on a V1NodeMCU (esp8266). The way I solved it was using the D2 gpio instead of the D1. ...
The temperature measurement range spans from -40 to 125°C, with an accuracy of ± 0.3°C, making it suitable for both indoor and outdoor use. The sensor's digital output and I2C interface provide a seamless connection to microcontrollers, simplifying data collection and reducing development ...
