  • 3-Pin Sound Sensor Module - Blue

    posted by fabio1964

    Verry cheap sond detection module for arduino projects with adjustable Gain for the mic to AO ratio at first i got almost no reaktion on the AO unles i made very high noices. But after som testing og trial an error type i found out that the gain was adjusteble.
    Nothing else to say, its very cheap but it works bad. I do not advise to buy this product.
    ok
  • Nice decorative piece

    This little gadget lights up in the dark with changing LED colors through a prism of some sort that breaks the light into several beams. its a nice night light - not too bright and provides a nice mood setting atmosphere. It supports 220V electrical voltage.
    Nice mood setting, energy saving device.
    Recommended for mood setting and not for night reading.
  • great shower! low price!

    price! price! the connections is made of plastic. but by this price, is acceptable.
    none. price! buy. buy. although the quality is not expected, worth the price charged. I believe that the plastic part, when broken, can be replaced.

  • poor documentation, but works ok, and at least comes with a cable

    Works in analog mode.Returns either 0 or 1 in digital mode.
    I would like to see wavelength specific sensors, specifically red, orange, yellow, green and blue, so as to get some rudimentary means of measuring light spectrum.I will probably order a handful of these and install color filters that do not degrade in sunlight.
    worth the $4
  • Good, but could be better.

    - high visibility- mini-pattern- lights up when it detect light- water-proof seal
    To resume the pros and cons, those lights works when it's dark and when there are in movement. When static, it lights up for a few second when passing from dark to light, which give to the bike (or whatever else) something cool.The problem to me is that the sensor is to sensible, so when the brightness of the environnement comes to a well lightened road in a city or in a room with artificial light it stays off.
    Worth it more if you are riding in a dark environnement.
