In this project, you’re going to build a data logger with the Raspberry Pi and the DHT11/DHT22 sensor that automatically stores temperature, humidity, and the corresponding timestamp on a.txtfile. This project gives you the basics of data collection, which is useful in many different applic...
DHT11接线说明 VCC接上3V3,可以选择1口或者17口 DATA接上GPIO口,我选的是GPIO2,第3口 GND接上接地口,我选的是第14口 把二极管接入到GPIO3 请注意二极管分为正负极,长的一端为正极,短的一端为负极。 把树莓派接入到AWS IoT 完成以上设备注册操作之后,就可以使用MQTT 连接到AWS IoT了。之后就可以远程看到...
Create a basic Raspberry Pi Pico local web server to control outputs and fetch data. You'll build a web page to control an LED on and off and fetch some random values generated by the Pico.

Most likely you are running the file from another raspbery where your MQTT server is not located. Make sure you alter the variable ‘servername’ in the mqtt.dhtsensor.py file into the servername or ip number where your mqtt broker is situated. Also make sure you do not have two clients...
Many thanks for this tutorial. I wish to use mqtt to get readings of the current temperature from a sensor in a raspberry pi. I used the code to read the temperature. I tested the code and everything is working out fine However, I tried to adapt the code to perform the reading using...
Interface a PIR motion sensor with the Raspberry Pi Pico to detect motion in your surroundings. Wire the sensor to the Pico board and program using MicroPython firmware.
