Identifying a Sensor for Dark, X-Axis Motion Detection

[3301]

I need to indentify this type of sensor.

Need to work in dark.
Need to scan only in x axis. ( not to have angle in y-axis only in x ) Something like a plate.
And needs to react when movement is changed in that plate.

Hi
Not sure I understand your question 100%, are you looking for a 2D scanner? They're not cheap if this is for some DIY project.

Hmm.. that may be it.

Can you post a sketch of what you want this sensor/scanner to do? And when you say "plate", do you maybe mean "plane"?

@berkeman
Yea plane :) My bad.

Well for example: if i put sensor 2m on my wall it need to detect movements on that height not lower. I am 2.1m and it detects me. My cat is .2m and it doesn't detect her.
Also need to have range: 3-5m minimum.

Can you use a Passive InfraRed (PIR) sensor that only sees from 2m up?

Passive InfraRed (PIR)

Interesting. Will search it.

You can use a motion detector from a security system, and block off parts of the window with tape on the inside. Trial and error, but relatively cheap. Most have no/nc contacts for triggering another device.

You can buy IR beam systems. They comprise an IR transmitter and receiver. Alarm triggered when the beam between the two is broken.
