One lesson was that I could perform all sensor data computation and visualization in the browser, so I don’t need much in the way of microcontroller capabilities. The ESP32 I used for AS7341 web UI was overkill. All I needed was an I2C bus and WiFi, so I could easily drop down to...
Arduino is an open-source electronics platform based on easy-to-use hardware and software. Arduino boards are able to read inputs - light on a sensor, a finger on a button, or a Twitter message - and turn it into an output - activating a ...
一旦完成Matter协议的占用传感器部署,用户可以在他们的智能家居生态系统(如Amazon Alexa、Google Home和Apple HomeKit)中设置自动化和例行任务。这些自动化可以根据传感器报告的占用状态控制灯光的开关,从而通过在无人区自动关闭灯光实现节能。 Thread网络的优势
