UPDATE: Replaced my PIR-Sensor with a Doppler Microwave Sensor.

@cowboysdude Great News, excellent!👍🏻

@cowboysdude
am I seeing it right that also the side of the case looking at you is aluminium taped?
So the whole case is taped in your case?

@cowboysdude @Fozi Guys, which module are you using for the recognition?
I can’t get neither MMM-PIR-Sensor nor MMM-PIR to work currently. Both have the same problem with epoll which is installed via the node module “onoff”, if I see correctly.
What are you using?
THe mirror won’t load with any of the modules activated giving the error

 The module '/home/pi/MagicMirror/modules/MMM-PIR/node_modules/onoff/node_modules/epoll/build/Release/epoll.node'
was compiled against a different Node.js version using
NODE_MODULE_VERSION 67. This version of Node.js requires
NODE_MODULE_VERSION 64. Please try re-compiling or re-installing
the module (for instance, using `npm rebuild` or `npm install`).

@cowboysdude I remember you’re using your own script?
@Fozi you?

node v 11.4.0
npm v 6.13.0

@lavolp3 I use my own for that… it’s not a module but it’s right here.

Easy to follow :)

The box is just a cardboard box taped with alum duct tape. I am however waiting for my trimmer resister so I can tune it down and take it out of the box. I only want the mirror to come on when someone walks up to it…say like 2 ft. away… so it doesn’t come on when I walk by the bathroom doorway… looks more like a pro thing :)

@lavolp3 I use MMM-PIR-Sensor without any modifications. Are you using @paviro master oder any other fork of the module?
As I see, you have more recent npm/node versions installed.
I am still on node 10.17.0 / npm 6.11.3.

Edit: I’d recommend to try the script from @cowboysdude . It is robust against any node.js stuff as it written in python.

It is important to replace the PIR sensor with a Doppler Microwave Sensor.

This spam bot is sooo right!:face_with_tears_of_joy:

@Fozi Hi
Can i solder pin 1 and 2 of the resistor to the radar sensor? I accidentally broke pin no 3.

[Fozi]

@bachoo786 yes, you can also use pin 1 and 2.

An example:
The max value of the resistor (Rmax) is between pin 1 and 3.
Between pin 1 and 2 is the restitor value R1, and
between pin 2 and 3 is the resistor value R2.

Rmax = R1 + R2. (or R1=Rmax - R2, resp, R2=Rmax - R1)

Thus, you can use both options (R1 pin 1/2 or R2 pin 2/3).

@Fozi so I got a new radar sensor set the resistance to 80ohms which would give me around 40 to 50cm detection distance. I am using @cowboysdude script.

My mm is running on my rpi 4b 4g and at present its connected to my TV. However the rada sensor is not working as the script is meant to detect motion and if there is no motion it would turn the tv off after 20 seconds. I tried many times but have failed.

Any ideas? Or maybe my sensor is not working. Is there a simple script that I could test the sensor?

Thanks.
