🔥犀利点评
这类项目最有价值的地方不是炫技，而是路线选择：全现成板卡、无云无账号、LoRa加ESP-NOW双通道组网，等于给被智能家居厂商锁死账号和订阅的用户指了条活路。ESP32-P4性能足够驱动10.1英寸大屏，SEN66一颗搞定四项空气指标，复刻门槛极低。缺点也明显——没有一体化外壳和量产，本质上仍是极客玩具，但它证明了本地化环境监测完全可以绕开云厂商。
Harald Kreuzer has built an ESP32-P4 weather station and air quality monitor that features a 10.1-inch dashboard display and a built-in Sensirion SEN66 sensor for particulate matter, CO2, VOC, and NOX, and connects to wireless LoRa and ESP-NOW sensors. The project is entirely made of off-the-shelf boards, so no custom hardware is used, and it should be relatively easy to reproduce. It doesn’t require any cloud or user account, although it can connect to a choice of weather APIs (Open-Meteo, OpenWeatherMap or Visual Crossing) to display weather forecasts. The build is fully documented in a long blog post, so we’ll highlight the key features of the project in this article. Hardware specifications for the main unit: Based on ESP32-P4-Module-DEV-KIT-C Credit card-sized ESP32-P4-Module-DEV-KIT SBC based on an ESP32-P4NRW32 module with ESP32-P4 with 32MB PSRAM and ESP32-C6 for WiFi and BLE 10.1-inch IPS panel with 1280 x 800 resolution, 800:1 contrast ratio, [...]
