    • RE: Bluetooth Proximity Sensor

      @Øyvind-A.-Espnes I haven't tried it, but with the AT+INQM command you can specify wether you want the RSSI of the device when issuing the AT+INQ command. This document can better explain it.

      After that it should just be a matter of parsing the resulting string and extract the signal strength.

    • RE: Bluetooth Proximity Sensor

      @Konrad-Walsh At the end I got the HC06 to work, I'm finally understanding all of this, if you tell me what you're trying to accomplish and the code u have I might be able to help. Also the module you're using.

    • RE: Bluetooth Proximity Sensor

      @hek When you say you inverted the polarity... are you talking about VCC and GRD? or Rx and TX?

    • RE: Bluetooth Proximity Sensor

      @Konrad-Walsh For what I know, the HC-06 is automatically configured to take in AT commands, so that shouldn't be a problem, although mine (that I got today) seems to be defective as I send it the AT command, but I'm getting no answer.

      In that case I don't think this the right place, as the site is mostly intended to help you controlling sensors and actuators using (mainly) Arduinos. The only thing I can tell you is that buying through ebay (though I prefer Amazon) is usually reliable, provided you can return the purchased, defective item within 30 days of purchase. In my case, since I live outside U.S., that's usually an inconvenience due to local taxes.

      When you're done with that, if you still need help with automating the operation of your LEDs array, let us know.

    • RE: DIY Outdoor LED

      @bjornhallberg I'm new to the forum and just got my Arduino today (still waiting for the other parts to arrive for my project), so I can't yet explain how to write any code, however I understand the following:

      • 1 - The design of your circuit has little to do with the sensor you use to operate them, thus you can decide on which LEDs to buy based on power consumption only (and maybe the capability to dim with burning).

      • 2.- Then you can build your circuitry and plug it in normally to the power source.

      • 3.- After you know the circuit works properly, THEN you bring the sensors.

      Basically you would use these sensors to control when the lights turn on/off, and that can be done in a variety of ways and with an array of different sensors.

      In my case, for example, I'm trying to open/close a circuit based on proximity, pretty much what you want, but I plan on doing so using a bluetooth module for the Arduino that pings my phone to see if its around, given the phone is found, the Arduino would emit voltage in a pin and that should (I still have no idea, but somehow) open the circuit and stop it from functioning, given the phone is out of reach, the voltage is stopped, and the circuit goes back to operating normally.

      In your case I don't think this would be a good approach because you want it to work whenever someone comes close, so maybe PIR sensors, or pressure plates, or IR sensor in the walkway or any other sensor you can use to identify someone's around.

      I would recommend you go and complete steps 1 and 2 and then come back with an idea of how you want to interact with your new circuit and the folks here will help you out on which sensors are better suited for you.

    • RE: Controlling 12v Signal with Proximity Sensor

      PIR sensors

      Not anyone, a sensor that generates a signal when I come close to the car, I rather it not be IR since, AFAIK, they need to be in specific positions to work, unlike NFC or Bluetooth that cover areas around the sensor.

      Basically I'm trying to create a smart switch that goes on or of based on whether I'm close (in the range of 10-20 feet) to it or not.

    • Controlling 12v Signal with Proximity Sensor

      Hello everyone, I'm considering starting my first project and don't know where to start (aside from MySensors of course), I have a 12v circuit which I'd like to interrupt based on proximity, basically I want it to operate normally but interrupt when I come close (I was thinking a bluetooth proximity sensor connected to the phone, but I'm open for any ideas).

      I'm installing this on a car so the "switch" needs to run on batteries, I think I could make it work out of the battery of the car but since the device actually runs when the car is off; I'm concerned about the battery drain over an extended period off.

      So the questions basically are:

      • What is the best approach for this proximity switch?
      • What hardware to I need?
