void loop() { TempAndHumidity data = dhtSensor.getTempAndHumidity();//接受来自传感器的温度湿度数据,存入data变量 Serial.println("Temp: " + String(data.temperature, 2) + "°C");//开始通过串口显示变量的温度信息 Serial.println("Humidity: " + String(data.humidity, 1) + "%");//显示湿度...
Monitoring temperature is critical in many different applications. If the battery temperature is very high, you stop charging. If the CPU is overheating, you either improve the heatsink or reduce CPU speed. Temperature monitoring is also needed in food industries for storage. To make sure the fo...

在科幻电视剧《星际迷航》中,三录仪(Tricorder)是一种多功能的便携式设备,能够感知环境、分析物质成分、甚至进行医疗诊断。如今,这种看似只存在于科幻中的设备,正在逐渐走进现实。今天,我将为大家介绍一个非常有趣的 DIY 项目——Tinycorder。这是一个小巧的多功能设备,旨在向《星际迷航》中的三录仪致敬。它不仅可以...
will learn how to use the ESP32-S2 internal temperature sensor to monitor temperature readings. We will create an example project provided by ESP-IDF that uses the temperature sensor driver. Through that example, we will demonstrate the use of the necessary APIs to fetch the temperature readings...
Pins without internal pull up GPIO13 GPIO25 GPIO26 GPIO27 GPIO32 GPIO33 In arduino to use these pins you can simply use common commands Example: To make GPIO22 as input and GPIO23 as output pinMode(22,INPUT_PULLUP); pinMode(23,OUTPUT); ...
The example above is for an ESP32 Webserver that reads the LM35 temperature sensor and provides this data for other devices. The ESP32 Creates a WiFi network and other devices on this network can get the temperature data shared by the ESP32 webserver (access point mode)....
