Merhaba, hareket sensörü (PIR) üzerindeki titreşim etkisini sormak istiyoruz. Şematiği şu şekilde belirledik:

Bu nedenle, cihaz üzerinde herhangi bir titreşim meydana geldiğinde, sensör yanlış tetikleme ve dolayısıyla yanlış his verir. Bu nedenle, herhangi bir titreşim meydana geldiğinde, sensör yanlış tetikleme yapıyor ve dolayısıyla yanlış his veriyor. Peki, bu sorunu çözmek için ne yapmalıyım? Bu hassasiyeti devre üzerindeki bileşenlerle ayarlayabilir miyim?

Hello, we want to solve the motion sensor (PIR) vibration problem. We determined the schematic as follows ;

Therefore, whenever any vibration occurs in the device, the sensor gives false triggering and therefore false sensation. So what should I do to fix this problem? Can I adjust this sensitivity with the components on the circuit?

Hello Kerem,

I am assuming that you are using the booster pack and launch pad with the GUI, please correct me if this assumption is incorrect.

Does your GUI look like this with the vibration?

Or is the high and low thresholds being triggered with the vibration of the board? I believe that some hardware adjustments might lower the sensitivity of the design but overall the PIR will be triggered with the vibration.

Either way, I believe you will find most success in changing the hardware values following this document: https://www.ti.com/lit/an/snaa301a/snaa301a.pdf

All the best,
