    Triple Axis Accelerometer

    Thanks for pointing me to the data sheets.

    I cant find the pin outs for the accelerometer. I assume P1, P2, and P3 are for each axis, Which side does the red (+) wire go to? Also, what is P4 used for.


    Thanks,

    Glenda

      red/+ goes towards edge of board. P1/P2/P3 are for each axis - it'll respond to gravity, you'll see.

      P4 are jumpers to change the sensitivity.

      You'll probably want to do some noise filtering. high sample rate + averaging will do.

        "P4 are jumpers to change the sensitivity." Anyone have a link to a retailer that sells these jumpers? - they did not come with my accelerometer.

          Any 0.1" jumper will fit. They are the standard jumpers found on the backs of harddrives, CD/DVD drives, pretty much anything. You can buy them lots of places. If you are in the US, then Mouser/DigiKey/Jameco all sell this stuff.

            If my current sensor has R0903113 on it, is it a Allegro ACS754-050?

            thanks,

              If you bought it from us, and it looks like the picture, then yes.

                Hehe, well I just want to be sure after the relay debacle. Have you considered putting links to to appropriate docs on each oscommerce description page for the products so they are easy to reference? That way if you get a different model/version of a product each will have a reference to the right docs for it.

                  Any chance of getting a description of the jumper settings?

                    relay: what connects to what?

                    What are the three connections on the relays for? I suppose one is + one is - and the other is ? There is no indication on the male pins. I assume that the power out is very small? So, say I want it to switch on a 110v outlet. What do I need?
                    Thanks

                      It is a standard relay.

                      There is a common, a normally connected, and a normally not-connected.

                      Relays have no polarity. The coil sides are wired to the little header pins that plug into the FB.

                      You can switch 25A with these relays. If you want 110vac AC then just connected to common and either NC or NO depending on how you want it to work.

                        Check out post #4 in this thread for a good visual on using a 120VAC relay:

                          nothing is standard

                          Geesh... you explain, like a doctor... or worse... an accountant!

                          What is the purpose of a "normally not-connected" pin. "Common" is common to what? Where do I get the mating connector for these relays and what are they called? (Perhaps you sell them as well?)

                            Perhaps a general read up on relays will help. Look at this part of wikipedia: http://en.wikipedia.org/wiki/Relay#Pole_and_throw

                            Explains NO, NC, and Common. We sell SPDT relays so the picture there should help too.

                            The mating connector for the FB is already soldered on. The mating connector for the relay terminals is a generic spade connector. Available at an auto store or even Radioshack.

                              You can likely get a 100 pack at Autozone for the price of 5 at Radioshack, or such was my experience...2 years ago...

                              (The Volume Control (Linear Variable Resistor) datasheet doesn't give a pinout, and I seem to have lost my multimeter)
                              ((The supplied cable isn't soldered to the resistor, which is fine but still need to know which is power, ground, the analog signal, and if the LED should be tied directly to the +5V (likely not! ) )
