DHT20 I2C Humidity and Temperature Sensor (for ESP-IDF)

This the I2C version of the popular DHT11 sensor (I assume, actually I don't know).

Setup

This time I created an extra component called TOOLBOX which contains my most often used functions especially for I2C.
I menuconfig the DHT20 sensor has a dependency on TOOLBOX so first enable and configure this component before you can enable the DHT20 Sensor.

Run: "idf.py menuconfig"

And configure:

And no you can enable the Sensor:

See esp-idf-dht20.c in the main folder for some basic usage.

Initialize the I2C bus and sensor by first calling:
dht20_begin();

Declare a dht20_data_t struct to store your measurements. dht20_data_t my_values;

And call:

dht20_read_data(&my_values);

Call this function in a loop or in a FreeRTOS task (see example).
Values can be accessed via:

my_values->humidity;  
my_values->temperature;
