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: 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. It’s a 12V circuit, it has two outputs which I’d like to sense.

Great, thanks so much for your help! 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. However I’d suggest it would be best to measure.


DEI Viper 508d Manual and Advice?

Check the PDF Manual: Vei I’m starting to see what the term “pull-up resistor” actually means! Measure the output voltages with nothing connected, and then again with 10k resistor from output to 5V.

That means it’s grounding, right? When I first tried hooking this up to my Arduino I was worried about the sensor running on 12v. Is manuap something I can read online to get a better understanding? Without a resistor, it measures 0V when inactive, about 6. When the alarm is triggered the signal pin is connected to ground. I know thread is old.

If both generate an output then take note of the voltages involved. I didn’t want to pass that voltage into the Arduino and fry it.

I’m also trying to use this sensor, but confused about what the blue and green wires do. I took a few electronics courses back in college, but have forgotten most of it.

Hmm, rather unclear that document and my neck now aches I think it might mean the outputs are open-collector capable of mA sink. MarkT Brattain Member Posts: If 12V manuall need a level shifting circuit such as resistor divider. The blue wire is “alarm” – someone’s entered the smaller alarm perimeter. 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?


DEI Viper d Manual and Advice?

Thanks for your help! Eventually I realized that the signal pins are left floating when the alarm is not triggered. 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.

If only the latter works and gives This is the “manual”:
