DHT11 library for STM32 based on HAL drivers

DHT11 Library for STM32

This library is based on STM32 HAL Drivers.

Hardware

• Signal (S)
• Vcc (3.3V to 5.5V)
• Gnd (-)

Usage Example

Tested on STM32F103C8T6 (Blue Pill).

Timer frequency needs to be set to 1us (htim1 in this example) .

DHT11_t dht11;
DHT11_Begin(&dht11, GPIOC, GPIO_PIN_14, &htim1);
DHT11_Read(&dht11);
float temperature = dht11.temperature;
float humidity = dht11.humidity;
