MCU通过一条数据线与DH11连接，MCU通过这条线发命令给DH11，DH11再通过这条线把数据发送给MCU。 温湿度模块的核心就是 MCU发给DH11的命令格式和DH11返回的数据格式。 时序： 首先MCU发送一个开始信号S，这个开始信号是一个低脉冲，然后再拉高。等待DHT11应答。

The project integrates an Arduino with a DHT11 sensor for measuring temperature and humidity, along with an RTC DS3231 module for maintaining real-time clock functionality. The Arduino periodically ...

In this tutorial, we'll guide you through interfacing an Arduino with an ultrasonic sensor to measure distance and show it on the Serial monitor. We'll start by explaining how to interface the ...

In this article, I have added three sensors with Arduino UNO and user can choose the required sensor with the help of keypad. Hi there! I hope you are doing great. Today I am sharing the Proteus ...
