/*
TITLE: 
    rz_dht.h

BRIEF:
    library

DESC: 
    Arduino lib for ESP32 DHT11, DHT22 (AM2302), DHT21 (AM2301) Sensors

SOURCE: 
    https://github.com/Zheng-Bote/esp32_libs

SYNTAX:
    #include "rz_dht.h"
    RZ_DHT *dhtsensor = new RZ_DHT();
    
    void readData();
    String getTemperature();
    String getHumidity();
    bool getSensorStatus();

RETURN:
    void // read current sensor data
    String temperature // 23.15 // °C
    String humidity // 45.55 // %
    bool error // true = sensor error, false = sensor reading ok

HISTORY:
Version | Date       | Developer  | Comments
------- | ---------- | ---------- | ---------------------------------------------------------------
1.0.0   | 2022-02-26 | RZheng     | created 
1.1.0   | 2022-02-27 | RZheng     | fixed: some low quality DHT sensors needs 1 second pause
