Connect sensor

Import

const { HCSR501 } = require("hc-sr501-sensor")

Constructor HCSR501(sensorPin, delay)

Parameters

• sensorPin You have to specify the GPIO pin where the sensor is connected to.
• delay This parameter is optional. You can specify a delay in milliseconds to stop motion detection. The smallest number is 3000.

Example

const sensor = new HCSR501(17, 3000)

sensor.watch((motion) => {
    // motion = boolean
    if(motion) {
        // do something
    } else {
        // do something else
    }
