ESP32-DHT11

Esp-idf driver for DHT11 temperature and humidity sensor

Install

Use Platformio to install this link
or
Clone this repo inside [esp]/esp-idf/components folder

How to use

Import dht11.h inside your program, initialize the device with DHT11_init(gpio_num) and then call DHT11_read() whenever you need to read from the DHT11 sensor.
DHT11_read() returns a struct with temperature and humidity and a status code of the operation for error checking.

Check the examples folder for more information.

WARNING: DHT11_read() is a blocking function.

esp32-dht11's Issues

waiter.h

where can i get waiter.h file??

Platformio requires the "include" directory to find the header

For both dht11.c and importing dht11.h from any project, platfomio finds it under "include/dht11.h"

IO problem

I'm using an esp32c3 chip, but I'm having a really weird problem. If DHT11 DATA can only be used when it is connected to IO2 or 8 and 9, it can be used normally. However, connecting other I/O ports will always return -1 and so on. I checked the manual and found that these three usable IO ports are Strapping pins. Now if I want to connect DHT11 at other IO ports, what should I do?
