This post explains, the method of retrieving the Humidity & Temperature data from the DHT11 sensor using Raspberry Pi Pico & MicroPython Code. The retrieved data will be displayed onPython Shell Windowand later
从网上找到了DHT11厂家说明书,尝试用python根据时序图写数据获取驱动,但发现python的高层特性导致在做底层代码时例如控制20us时延这类需求就没什么好的办法。 还是得回到C-wiringPi 控制gpio
#define HIGH_TIME 32 int wiringPiSetup (void) ; int pinNumber = 7; //use gpio1 to read data uint32 databuf; uint8 readSensorData(void) { uint8 crc; uint8 i; pinMode(pinNumber,OUTPUT); // set mode to output digitalWrite(pinNumber, 0); // output a high level delay(25); digi...

Hi, do you have this code also for Zerynth (Python language)? Reply Sara Santos April 17, 2020 at 11:23 am Hi. No. We have for MicroPython: https://randomnerdtutorials.com/esp32-esp8266-dht11-dht22-micropython-temperature-humidity-sensor/ Regards, Sara Reply Kurt Cafini April 29,...
The following is a code example using the DHT11 and the Python programming language. The code was written for the Raspberry Pi and is taken from my first book, Internet of Things Programming Projects (Packt Publishing). This code uses the Adafruit DHT library to measure temperature and humidity...
