BMP280 vs BME280 → https://www.wiki.lesfabriquesduponant.net/index.php?title=Capteur_BME280#Comment_distinguer_BME280_et_BMP280_.3F

5V vs 3.3V → https://www.wiki.lesfabriquesduponant.net/index.php?title=Capteur_BME280#Connecter_BME_280_.C3.A0_l.27arduino

J'ai un BME280 5V :

• Sketch > Include Library > Manage Libraries > adafuit bme280
• (Sketch > Include Library > Manage Libraries > adafuit unified sensor)
• File > Examples > Adafruit BME280 library > bme280test
• Comment lines (ligne 20) #include <SPI.h> et de /*#define BME_SCK 13 à #define BME_CS 10*/ (line 24 à 27)
• Ajouter 0x76 (ligne 46) → status = bme.begin(0x76);
