ESP32 Environmental Sensor Applications: Gas Sensor Applications

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
