readme
# Component: MVH3004D
## Add component to your project
Please use the component manager command `add-dependency` to add the `mvh3004d` to your project's dependency, during the `CMake` step the component will be downloaded automatically
```
idf.py add-dependency "espressif/mvh3004d=*"
```
## Example of MVH3004D 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 mvh3004d_handle_t mvh3004d = 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 mvh3004d
mvh3004d = mvh3004d_create(i2c_bus, MVH3004D_SLAVE_ADDR);
//Step3: Read tp and rh
float tp = 0.0, rh = 0.0;
mvh3004d_get_data(mvh3004d, &tp, &rh);
