Circuit diagram for HC-SR501 PIR and which inputs on RUT955?

Hello,

I tried to find out the correct wiring for a HC-SR501 PIR sensor.

I thought that the second circuit diagram (digital isolated input example) 

https://wiki.teltonika.lt/view/Using_RUT955_Inputs_for_security_applications

would be correct and that I have to select a suitable resistor.

But I got different voltage ranges for low / high if I either sourced only from the 12V battery within BOX102 or with the power supply to charge the 12V battery.

I sourced the PIR and the RUT955 together because the PIR should be suitable for 9 or 12V input voltage.

As resistor values I tried 470, 1k, 1,5k and 2,2kOhms.

It seems to be that the PIR started to toggle between low and high logical states.

I am not really sure if the digital isolated input example is correct for the HC-SR501 PIR

https://www.roboter-bausatz.de/media/pdf/40/39/c9/HC-SR501.pdf

Are the voltage ranges for low and high logic level correct?

https://wiki.teltonika.lt/view/RUT955_Input/Output#ON.2FOFF

I measured high starting at 7,8V. with 1kOhms.

Which circuit diagram is fool proof?

Any hint appreciated.

Hi,

PIR should be connected like this:

Hi,

Does your wired connection was correct? Do you still have issues with this?
by anonymous

Hi,

thanks for the wiring diagram. I didn't tried that before. Because my RUT955 is in a remote loaction at the moment I cannot answer if it is correct now. I'll keep you updated the next time after visit the remote location.

I plan to buy a 2nd RUT955, I am searching for a dealer where I can order the newest RUT955 T033C0

from which country you are?

Germany.

Last time I bought from EURO DK within Amazon portal.

Today I can see the updated picture which shows the new design (label with blue/black background) SIM slots in the case.

Is there another shop with a good price recommended?

The wired connection from the diagram above was correct and it works quite well til today.

Many thanks!
