Go package for reading temperature and humidity from DHT11, DHT22 and AM2302 sensors on Raspberry Pi

This package contains only one function for measuring temperature and humidity from DHT11, DHT22 and AM2302 sensors. The package uses a Go-adapted version of the WiringPi GPIO Library - Go WiringPi

Usage example

1. Download and install the WiringPi GPIO library on your Raspberry Pi
2. Create a Go file with the following content:

package main

import (
    "fmt"
    "gitfox.ru/victor/go-dht"
)

var (
    pin = 7   // Pin number (GPIO_7)
)

func main() {
    temperature, humidity, err := dht.ReadDHT(pin)
    if err != nil {
        fmt.Println("Read error!")
    } else {
        fmt.Printf("Temperature: &.1f °C\nHumidity: %.1f %%\n", temperature, humidity)
    }
}

3. Create a module file, for example, dht-reader:

go mod init dht-reader

4. Build the program:

go get
go build

5. Run your application to get the temperature and humidity.
