# AHT20 temperature and humidity sensor driver component for esp-idf
## Installation
idf.py add-dependency "larryli/aht20"
## Getting Started
### New i2c master
```c
#include "driver/i2c_master.h"
i2c_master_bus_config_t i2c_bus_config = {
.clk_source = I2C_CLK_SRC_DEFAULT,
.i2c_port = PORT_NUMBER,
.scl_io_num = SCL_IO_PIN,
.sda_io_num = SDA_IO_PIN,
.flags.enable_internal_pullup = true,
};
i2c_master_bus_handle_t bus_handle;
i2c_new_master_bus(&i2c_bus_config, &bus_handle);
```
### Init AHT20 device
```c
#include "aht20.h"
aht20_config_t aht20_config = {
.aht20_device.scl_speed_hz = MASTER_FREQUENCY,
.aht20_device.device_address = AHT20_ADDRESS,
};
aht20_handle_t aht20_handle;
aht20_init(bus_handle, &aht20_config, &aht20_handle);
```
### Get temperature and humidity
```c
float temperature, humidity;
aht20_get_temperature_humidity(aht20_handle, &temperature, &humidity);
```
