If you don’t want to miss my updates, remember to check the public account in the upper right corner and mark it as a star, and send me a star. Playing games, acting as a central control center, and even connecting to Raspberry Pi, what can you do with such a palm-sized open-source development board? … Read more
Welcome to the world of environmental sensing! Nowadays, with the ongoing issues of climate change and pollution, understanding and monitoring our surrounding environment has become very important. This is why we are discussing the BME680 sensor! The BME680 sensor can measure temperature, humidity, pressure, and even VOCs (volatile organic compounds). It provides us with valuable … Read more
ESP32 Gas Sensor Application Guide 1. Basic Principles and Selection Gas sensors operate by detecting electrochemical changes (such as resistance changes) caused by target gases. Common types include: MQ Series detects specific gases (such as smoke, liquefied gas) and outputs an analog voltage. Digital Sensors directly output I²C digital signals (such as BME680 for multi-parameter … Read more
