Edit: I originally posted about this 16-sensor kit for $10, then DaveJenson out-ercoed me with his 37-sensor kit for $12. Even I couldn't resist. DOH!

    Well played, my young Padawan!

    I ordered DaveJenson's kit. For $12, Mr. Roboto needs to check it out. Maybe there's a new contest in the offing to see who can use the most sensors on one project...

    Thanks Dave, you're keeping me on my toes!

    Edit: Changing the title.

    .. it includes a flame sensor module

    Noted! :)

  • I imagine this:

    1x Optical broken module

    is actually this

    Position sensors that activate when an object interrupts a light beam

    but I was amused.
    Re-inventing the wheel is not a waste of time if, when you are done, you understand why it is round.

    That's what I typically use my fingers for. Reset time is a little long, though, usually on the order of 2-3 days.

    Reminds me of the "Statue of Liberty" shots we used to do with Sambuca. Soak your fingers in the drink, then set 'em on fire & hold aloft until you take the shot. It doesn't pay to dally.

  • So this could use a lot of the sensors: a mobile burglar deterrent system, following a line around the area on patrol. It warns the miscreant with flashing leds..and ultimately flames him...and then measures the crispiness of the result.

    Love it! And I've always been a fan of "Crispy Critters".

  • I think the question should be, "Who DOESN'T need 37 sensors for $12??"

    Let''s see somebody fess up to that!

    Got my sensor kit today, having fun going through it sorting out my treasures. All 37 "sensors" (some are beepers or LEDs) present and accounted for. The sum of the parts is worth more than $12, if you can use them all...

    Found this site with more sensor info: https://tkkrlab.nl/wiki/Arduino_37_sensors

    Some interesting stuff. Most of them have pullup/pulldown resistors built in.

    But someone please tell me why this reed switch needs an
    lm393 comparator? https://tkkrlab.nl/wiki/Arduino_KY-025_Reed_module ?

    The touch sensor uses the base lead of a KSP13 darlington transistor as the touch point: https://www.alibaba.com/product-detail/AD-036-Metal-Touch-Interface-sensor_1890926598.html

    Optical pulse sensor: http://www.ebay.com/itm/Keyestudio-Heartbeat-Detect-Sensor-Finger-Pulse-Rate-Monitor-Module-FOR-Arduino-/311692638533

    Nice impact sensor, spring inside cylinder: https://tkkrlab.nl/wiki/Arduino_KY-002_Vibration_switch_module

    My list with a few notes attached.

    Probably for debouncing. Reed switches are notoriously noisy.

    Reed switches are notoriously noisy.

    So are my neighbors.

    I wonder if they would sit still long enough for me to solder them to a comparator. Or maybe just a big fat capacitor.

    Thanks for the suggestion!
