5 ESP32 projects that replace smart home gadgets you'd otherwise pay a subscription for
Why pay a premium for smart devices when an ESP32 and some cheap sensors can do everything for a fraction of the price?
Exploring the future of crypto,one reply at a time.
There are plenty of “robot” projects out there that are really just a small remote control platform of some sort. We often like to think of robots of having some sort of autonomy though. [Luca Fagioli ...
About five years ago, I worked on IoT for my job. I once used this DHT11 (a blue temperature and humidity sensor) to build a ...
Battery-powered e-paper sign: room signage, sensor graphs, home automation, or anything over Wi-Fi. Wakes by real-time clock, NFC tap, or button. Raspberry Pi Pico W firmware, custom PCB, and ...
In this project, I connected a DHT11 temperature and humidity sensor to a NodeMCU ESP8266 and used KiwisIoT to monitor temperature and humidity readings online. The ESP8266 collects data from the ...
它不依赖 Arduino IDE 的封装黑匣子，不调用 HAL 库里未公开时序细节的 HAL_Delay () ，也不用 CubeMX 自动生成一堆冗余初始化——而是直击底层：手动配置 RCC、GPIO、I²C、SysTick，用位带操作翻转引脚模拟 DHT11 单总线时序，用查表法加速 OLED 字模渲染。
你手头刚解压出 OLED+DHT11+烟雾.zip ，里面大概率是某开发者整理的 Arduino 或 ESP32 工程包——主控板接一块 0.96 英寸 SSD1306 OLED 屏、一个 DHT11 温湿度传感器、一个 MQ-2 烟雾/可燃气体模块。
