It is a small box that houses the sensor DHT22 and the uC ESP32 for it, it also includes an OLED screen that shows the temperature and relative humidity, it also includes the 18650 battery with its respective charge controller and also allows IoT mode.Download...
values. I wanted to combine all interesting functions into one library. In addition, none of the DHT libraries I found were written to work without errors on the ESP32. For ESP32 (a multi core/ multi processing SOC) task switching must be disabled while reading data from the sensor. ...
To test the code, simply follow the usual procedure of compiling it and uploading it with the Arduino IDE, after the wiring between the sensor and the ESP32 is done. Once the procedure finishes, open the Arduino IDE serial monitor. You should get an output similar to figure 1, where the...
I've been trying to make a temperature sensor based on the ESP32-C3-DevKitM-1 and using a driver from GitHub. I already tried 2 and both timeout trying to read from the sensor. Once I plug it into an Arduino, with the same pin configuration, it works. ...

怎样去编写一个stm32连接DHT11采集当前温湿度数据最近到手的wifi开发板,编写了一个stm32连接DHT11采集当前温湿度数据(为什么不直接使用esp8266的DHT模块直接采集温湿度,因为我发现nodemcu的DHT采集温湿度实在是太不准确了 dfgsdf 2021-11-01 07:24:39
