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.

If only the latter works and gives If both generate an output then take note of the voltages involved. That means eei grounding, right?

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.

How would I sense that, and is it OK to mmanual that resistor directly to the Arduino’s 5V power even though this runs on car 12V? Now I’m starting to see what the term “pull-up resistor” actually means! Thanks for your help! Eventually I realized that the signal pins dsi left floating when the alarm is not triggered.


But I found good input to the initial problem under: It’s a 12V circuit, it has two outputs which I’d like to sense. Is there something I can read online to get a better understanding? Without a resistor, it measures 0V when inactive, about 6.

DEI Viper d Manual and Advice?

When I first tried hooking this up manhal my Arduino I was worried about the sensor running on 12v. 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 know thread is old. I didn’t want to pass that voltage into the Arduino and fry it.

DEI D Field Proximity Sensor

When the alarm is triggered the signal pin is connected to ground. I’m also trying to use this sensor, but confused about what the blue and green wires do.

Great, thanks so much for your help! The blue wire is “alarm” – someone’s entered the smaller alarm perimeter. 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 connected, and then again with 10k resistor from output to 5V.


DEI Viper 508d Manual and Advice?

Open-collector ,anual 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. This is the “manual”: 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.

If 12V you’d need a level shifting circuit such as resistor divider. However I’d suggest it would be best to measure.
