pir-sensor's Introduction

PirSensor Class

This is the code block for using a PIR motion sensor with Windows 10 IoT Core. Check the Supported Devices section to see the list of tested sensors.

Usage

To use this block in your project, you need to perform the following steps:

  1. Navigate to your git project folder using Command Prompt and run git submodule add https://github.com/ms-iot/pir-sensor
  2. Next, run git submodule update
  3. Open your project solution in Visual Studio and right-click on the solution and select Add -> Existing Project. Select pir-sensor -> PirSensor -> PirSensor.csproj.
  4. Once PirSensor is added to the solution explorer, right-click on References in your project and select Add Reference -> Projects -> Solution. Check PirSensor and select OK.
    You should now be able to use PirSensor objects in your project.

Note: Every time you clone your project after its initial creation, you must run the following commands in the project's root folder:

  • git submodule init
  • git submodule update

Constructors

  • PirSensor(int, SensorType): Creates a new instance of the motion sensor taking the GPIO pin and type (SensorType.ActiveLow or SensorType.ActiveHigh) as arguments.

Note: See the Supported Devices section to see what sensor type to use.

Events

  • motionDetected: Occurs when motion is detected.

Methods

  • Dispose: Performs tasks associated with freeing, releasing, or resetting unmanaged resources.

Supported Devices

Manufacturer Sensor SensorType
Adafruit PIR (motion) sensor ActiveHigh
Sparkfun PIR Motion Sensor (JST) ActiveLow

pir-sensor's Issues

PirSensor Event Handler not invoked

I'm unable to get the motionDetected event handler invoked when there is motion in front of the HC-SR501 (PIR) sensor. I have used ms-iot examples for the PirSensor class and in a separate test cloned the GpioInterrupt example without any success. The same breadboard layout works fine with the equivalent (i.e. interrupt handling) in C++ and Python by swapping out the SD card. I have tried GPIO pins 26 and 6 (BCM numbers) without success for the sensor but Blinky (with the Timer event) works fine on these two pins.

I have tried the sensor with ActiveHigh and ActiveLow settings. For this particular model, ActiveHigh is the correct setting because that is the interpretation that I have in my test cases under Raspbian Jessie.

Any guidance available on debugging the GpioPinValueChangedEvent for a newbie user?

My W10 IoT Core tests have failed with five different HC-SR501 sensors and yet all of these work fine. Arduino Wiring will be my next test (since regular Arduino with interrupt handling is working fine) but some feedback on board level interrupt handling would be good education for me.

Thanks.
