sr501

HC-SR501 Sensor Go API

Provides a simple, easy-to-use API for interfacing with the HC-SR501 IR motion sensor on the Raspberry Pi platform using GPIO pins.

Features

• Simple API for easily detecting and responding to motion events
• Leverages [Periph.io]'s GPIO library for low-level communication on Pi hardware
• Customizable pin selection for binding event listeners to

Installation

go get github.com/littlehawk93/go-sr501

Getting started

Basic working example

wg := sync.WaitGroup{}
wg.Add(1)

// Bind the sensor signal pin to GPIO Pin #17
sensor, err := sr501.NewSensor("17", func() {

    // Print that motion was detected and unlock the wait group
    log.Println("MOTION DETECTED!")
    wg.Done()
})

if err != nil {
    log.Fatalf("Error initializing motion sensor: %s", err.Error())
}

defer sensor.Close()

sensor.Begin()

// Wait until motion has been detected before proceeding
wg.Wait()
