# Seeed_Arduino_AHT20 [![Build Status](https://travis-ci.com/Seeed-Studio/Seeed_Arduino_ATH20.svg?branch=master)](https://travis-ci.com/Seeed-Studio/Seeed_Arduino_ATH20)

## Introduction

AHT20 is a new generation of temperature and humidity sensor embedded with a dual-row flat and no-lead SMD package, suitable for the reflow soldering. AHT20 is equipped with a newly designed ASIC chip: an improved MEMS semiconductor capacitive humidity sensor, and a standard on-chip temperature sensor. 

## Usage 

```c++

// ARDUINO DEMO FOR GROVE-AHT20

//

#include 

#include "AHT20.h"

AHT20 AHT;

void setup()

{

    Serial.begin(115200);

    Serial.println("AHT20 DEMO");

    AHT.begin();

}

void loop()

{

    float humi, temp;

    

    int ret = AHT.getSensor(&humi, &temp);

    

    if(ret)     // GET DATA OK

    {

        Serial.print("humidity: ");

        Serial.print(humi*100);

        Serial.print("%\t temerature: ");

        Serial.println(temp);

    }

    else        // GET DATA FAIL

    {

        Serial.println("GET DATA FROM AHT20 FAIL");

    }

    

    delay(100);

}

// END FILE

```

## API

### void begin()

Initializing the AHT20

```c++

    AHT.begin();

```

### bool getSensor(float *h, float *t)

get all data of sensor

```c++

    int ret = AHT.getSensor(&humi, &temp);

```

### bool getTemperature(float *t)

get Temperature of sensor

```c++

    int ret = AHT.getTemperature(&temp);

```

### bool getHumidity(float *h)

get Humidity of sensor

```c++

    int ret = AHT.getHumidity(&humi);

```
