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.

DEI Viper 508d Manual and Advice?

Check the PDF Manual: Open-collector or open-drain, same thing outputs are nice and flexible like mahual you can wire several of them together to one pull-up resistor to make a hard-wired AND gate too.

This is the “manual”: That means it’s grounding, right? I didn’t want to pass that voltage into the Arduino and fry it. When the alarm is triggered the signal pin is connected to ground. Hmm, rather unclear that document and my neck now aches I think it might mean the outputs are open-collector capable of mA sink. Eventually I realized that rei signal pins are left floating when the alarm is not triggered. This means you can connect the signal pin manuap a Arduino digital input pin, but you need to connect it to a pull up resistor so you get a constant value.


If 12V you’d need a level shifting circuit such as resistor divider. But I found good manua, to the initial problem under: If both generate an output then take note of the voltages involved. I know thread is old.

Without a resistor, it measures 0V when inactive, about 6. I’m also trying to use this sensor, but confused about what the blue and green wires do. It’s a 12V circuit, it has two outputs which I’d like to sense.

Great, thanks so much for your help! However I’d suggest it would be best to measure. Now I’m starting to see what the term “pull-up resistor” actually means!

If only the latter works and gives The blue wire is “alarm” – someone’s entered the smaller alarm perimeter.

MarkT Brattain Member Posts: 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 triggered. di


DEI Viper d Manual and Advice?

I took a few electronics courses back in college, but have forgotten most of it. 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 dri

Is there something I can read online to get a better understanding? Measure the ddi voltages with nothing connected, and then again with 10k resistor from output to 5V.

Thanks for your help! When I first tried hooking this up to my Arduino I was worried about the sensor running on 12v.
