HeatIndex for lower values of temperature and humidity

1

The current algorithm used for calculating heat index takes into account Rothfusz equation to achieve the values that Robert G. Steadman came up by experimentation. It then has some refinements...

Problem: DHT22 does not send data in sign-magnitude format

- Arduino board 1: ESP8266 / NodeMCU 1.0 (ESP12-E Module) - Arduino board 2: ESP-WROOM-32 / ESP32 DEVKIT V1 - Arduino IDE version (found in Arduino -> About Arduino menu):...

The current DHT11 section of the DHT code -- to my understanding -- handles negative temperatures strangely: it FIRST transforms the integral part into negative by subtracting from -1, and...

Resolution reported for DHT11 temp is 2° - should be 0.1°, %RH should be 1% instead of 5%

1

See https://forums.adafruit.com/viewtopic.php?p=957161 for discussion thread. The **Resolution** values for both Temperature and Humidity are incorrectly defined in DHT-U.cpp for DHT11 sensors. Lines 213-217 ``` case DHT11: sensor->max_value = 80.0F; sensor->min_value...

define an empty constructor and overload DHT::begin

2

The use of an empty constructor allows for some more complex and flexible initialization logic without the need to write out every step explicitly.

Measured temperature is about 7-8 degrees(in Celsius) less than the real temperature

Hello, the code works for me, but i measure around 24-25 Celsius, but there is only 18 degress here. I use 3.3V supply(but i also tried with 5V) and a...

Improvement: Add a public getRawData() function

I am currently doing a project with an ESP32 where I need to store and transmit data over the internet from a DHT22, it would be nice to be able...

This adds two new methods to the DHT class. One for setting the _pin value and one for setting the _type value. The reason I added these was so that...
