espressif/veml6075

# Component: VEML6075 The VEML6075 senses UVA and UVB light and incorporates photodiode, amplifiers, and analog / digital circuits into a single chip using a CMOS process. When the UV sensor is applied, it is able to detect UVA and UVB intensity to provide a measure of the signal strength as well as allowing for UVI measurement. ## Add component to your project Please use the component manager command `add-dependency` to add the `veml6075` to your project's dependency, during the `CMake` step the component will be downloaded automatically ``` idf.py add-dependency "espressif/veml6075=*" ``` ## Example of VEML6075 usage * This component will show you how to use I2C module read external i2c sensor data, here we use veml6075 UV light sensor(color sensor) 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 veml6075_handle_t veml6075 = NULL; //Step1: Init I2C bus i2c_config_t conf = { .mode = I2C_MODE_MASTER, .sda_io_num = VEML6075_I2C_MASTER_SDA_IO, .sda_pullup_en = GPIO_PULLUP_ENABLE, .scl_io_num = VEML6075_I2C_MASTER_SCL_IO, .scl_pullup_en = GPIO_PULLUP_ENABLE, .master.clk_speed = VEML6075_I2C_MASTER_FREQ_HZ, }; i2c_bus = i2c_bus_create(VEML6075_I2C_MASTER_NUM, &conf); //Step2: Init veml6075 veml6075 = veml6075_create(i2c_bus, VEML6075_I2C_ADDRESS); //Step3: float uva = veml6075_get_uva(veml6075); float uvb = veml6075_get_uvb(veml6075); float uv_index = veml6075_get_uv_index(veml6075); ```
