espressif/bme280

# Component: BME280 The BME280 is as combined digital humidity, pressure and temperature sensor based on proven sensing principles. The sensor module is housed in an extremely compact metal-lid LGA package with a footprint of only 2.5 × 2.5 mm² with a height of 0.93 mm. Its small dimensions and its low power consumption allow the implementation in battery driven devices such as handsets, GPS modules or watches. ## Add component to your project Please use the component manager command `add-dependency` to add the `bme280` to your project's dependency, during the `CMake` step the component will be downloaded automatically ``` idf.py add-dependency "espressif/bme280=*" ``` ## Example of BME280 usage Pin assignment: * master: * GPIO2 is assigned as the clock signal of i2c master port * GPIO1 is assigned as the data signal of i2c master port * Connection: * connect sda of sensor with GPIO1 * connect scl of sensor with GPIO2 ```c static i2c_bus_handle_t i2c_bus = NULL; static bme280_handle_t bme280 = NULL; //Step1: Init I2C bus i2c_config_t conf = { .mode = I2C_MODE_MASTER, .sda_io_num = I2C_MASTER_SDA_IO, .sda_pullup_en = GPIO_PULLUP_ENABLE, .scl_io_num = I2C_MASTER_SCL_IO, .scl_pullup_en = GPIO_PULLUP_ENABLE, .master.clk_speed = I2C_MASTER_FREQ_HZ, }; i2c_bus = i2c_bus_create(I2C_MASTER_NUM, &conf); //Step2: Init bme280 bme280 = bme280_create(i2c_bus, BME280_I2C_ADDRESS_DEFAULT); bme280_default_init(bme280); //Step3: Read temperature, humidity and pressure float temperature = 0.0, humidity = 0.0, pressure = 0.0; bme280_read_temperature(bme280, &temperature); bme280_read_humidity(bme280, &humidity); bme280_read_pressure(bme280, &pressure); ```
