Adafruit BME280 library [PORTED]

[Alli]

Hello @manjil123

Firstly, make sure that you have connected your BME280 correctly to your particle device. I used a particle photon, thus pins D0 and D1 (SDA and SCL) are the I2C pins as shown in the pinout diagram in this link:

Ensure that your BME280 is connected to the photon as shown in this link:

BME280 reading problem

Hi. I’m triying to connect a bme280 and I have a lot of problems. wire connection: [image] The code #include "Adafruit_BME280.h" #include "Adafruit_Sensor.h" Adafruit_BME280 bme; // I2C // I2C wiring #define BME_MOSI D0 #define BME_SCK D1 #define SEALEVELPRESSURE_HPA (1013.25) unsigned long lastUpdate = 0; char buf[64]; void setup() { Serial.begin(9600); Serial.println(F("BME280 + OLEDisplay 128x64")); if (bme.begin()) { Serial.println("BME280 sensor works!"); …

You will need to include the CE_BME280 library in your project first. Then use these instructions in your program to poll measurements from your BME280:

Pressure = (bme.readPressure()/100);                 //Pressure measurements in hPa
Temperature = bme.readTemperature();
Humidity = bme.readHumidity();

Its as simple as that. If you are still having a problem, post the program you created so that we can see what you are doing and try to help
