I’d like to hook up a DEI D Field Proximity Sensor to an Arduino. This is the “manual”: Manual or automatic transmission selection. Note: In the case of D, power and ground must be hardwired to the . DEI feature error. Protect your vehicle with an invisible sensing field which detects moving high- density objects (including people) near your car using Radio Frequency (RF) field.

But I found good input to the initial problem under: Eventually I realized that the signal pins are left floating when the alarm is not triggered.

Is there something I can read online to get a better understanding? This is the “manual”: If both generate an output then take note of the voltages involved. The blue wire is “alarm” – someone’s entered the smaller alarm perimeter.

It’s a 12V circuit, it has two outputs which I’d like to sense. I took a few electronics courses back in college, but have forgotten most of it. Check the PDF Manual: Measure the output voltages with nothing ddi, and then again with 10k resistor from output to 5V.


DEI Viper d Manual and Advice?

Now I’m starting to see what the term “pull-up resistor” actually means! When the alarm is triggered the signal pin is connected to ground. Without a resistor, it measures 0V when inactive, about 6. How would I sense that, and is it OK to connect that resistor directly to the Arduino’s 5V power even though this runs on car 12V?

That means it’s grounding, right?

MarkT Brattain Member Posts: Hmm, rather unclear that document and my neck now aches I think it might mean the outputs are open-collector capable of mA sink. I’m also trying to use this sensor, but confused about what the blue and green wires do. This means you can connect the signal pin to a Arduino digital input pin, but you need to connect it to a pull up resistor so you get a constant value.

DEI Viper 508d Manual and Advice?

However I’d suggest it would be best to measure. When I first tried hooking this up to my Edi I was worried about the sensor running on 12v. Great, thanks so much for your help!


Thanks for your help! I know thread is old. I didn’t want to pass that voltage into the Arduino and fry it.

If only the latter works and gives With a 10K resistor connected between the output and the 16V rail sorry, no 5V available right nowit reads 15V at the output when inactive, but drops to zero when 5508d. If 12V you’d need a manhal shifting circuit such as resistor divider. Open-collector or open-drain, same thing outputs are nice and flexible like this you can wire several of them together to one pull-up resistor to make a hard-wired AND gate too.
