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 D Field Proximity Sensor
I didn’t want to pass that voltage into the Arduino and fry it. Without a resistor, it measures 0V when inactive, about 6. Is there something I can read online to get a better understanding?
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? This is the “manual”: I know thread is old. Hmm, rather unclear that document and my neck now aches I think it might mean the outputs are open-collector capable of mA sink.
If 12V you’d need a level shifting circuit such as resistor divider.
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.
When I first tried hooking this up to my Arduino I was worried about the sensor running on 12v. MarkT Brattain Member Posts: I took a few electronics courses back in college, but have forgotten most of it.
However I’d suggest it would be best to measure.
If both generate an output then take note of the voltages involved. Eventually I realized that the signal pins are left floating when the alarm is not triggered.
That means it’s grounding, right? Manjal the alarm is triggered the signal pin is connected to ground. Measure the output voltages with nothing connected, and then again with 10k resistor from output to 5V.

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. If only the latter works and gives Check the PDF Manual: Now I’m starting to manial what the term “pull-up resistor” actually means! Thanks for your help! Great, thanks so much for your help!
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.
The blue wire dek “alarm” – someone’s entered the smaller alarm perimeter. But I found good input to the initial problem under: I’m also trying to use this sensor, but confused about what the blue and green wires do.
