Thread: PIR Sensor #555-28027 and the debug window.

  1. #1

    Default PIR Sensor #555-28027 and the debug window.

    I am using the PIR Sensor #555-28027 and playing with the sample code that comes with it as seen below:
    ' ================================================== =======================
    ' File...... PIR_Simple.bs2
    ' Purpose... Show Output State Of PIR Sensor
    ' Author.... Parallax, Inc.
    ' E-mail.... support@parallax.com
    ' Started... 12-14-2005
    ' {$STAMP BS2p}
    ' {$PBASIC 2.5}
    '
    ' -----[ Program Description ]---------------------------------------------
    ' This program displays the current state of the PIR Sensor connected to P9
    ' on the DEBUG screen.
    ' -----[ Program Code ]----------------------------------------------------
    Main:
    DO
    DEBUG HOME, BIN1 IN9 ' Display Status Of P9 At Home Pos.
    PAUSE 100иииииииииии ' Small Delay
    LOOPииииииииииииииии ' Repeat Forever

    I have the sensor set to High which does this:
    Output remains HIGH when sensor is retriggered repeatedly. Output is LOW when idle (not triggered).
    I have the Basic Stamp 2P40.
    I have the sensor wired up with an LED on its output to verify that the sensor is indeed triggering.и However I am stumped with the zero in the debug window when my sensor is triggered or not.

    Are you connected to P9 on the BASIC Stamp? MAIN or AUX bank? Also, how much current is the LED drawing? The output wasn’t really intended for that purpose.

    Hey Wrath......,

    иI used an led too... but put it on it's own output pin with a 470 resistor.

    Use code to make out high to Led when PIR is sensing.
