: Lancement du 2ème bus I2C sur ESP32 avec le capteur CCS811

Je souhaite connecter deux capteurs CCS811 avec une carte de développement ESP32. Étant donné que les capteurs ont une adresse fixe, je ne peux pas les utiliser simultanément. J''ai lu que sur ESP32, plusieurs bus I2C peuvent être créés. En essayant de suivre cette route, j''ai essayé de modifier la bibliothèque mais je suis bloqué. Je ne peux pas simplement passer des broches ...

ESP32 Anomaly detection using Edge Impulse and machine ...

Acquire data using ESP32, CCS811 and Edge Impulse. The first step is acquiring data using ESP32 and CCS811: we will acquire CO2 concentration and tVoC (volatile organic compounds). This data will be forwarded to Edge Impulse. Before building this project is necessary to create an Edge Impulse account for free and a new project. Upload this code to the ESP32: include <> include ...

How to monitor air quality CO2 using ESP32 and CCS811

The CCS811 sensor is a gas sensor that is able to detect several compounds in the air. It can measure the equivalent CO2 present in the air and the total volatile organic compounds named VOCs. These are a class of compounds that are considered pollutants and sensory irritants. They are produced by a variety of sources including people’s breath.
