sensor red Customers Reviews

  • Good gas detector.

    posted by Nioderam2

    Good gas detector with high sensitivity. I tested it in a variety of settings and are very pleased with the results. May also be used as a simple detector - LED lights up when the gas detects.
    When I tested it, i noticed that it reacts to moisture, and detects it. May want to protect the sensor from moisture.
    It is extremely simple to use. Perfect for DY projects. However, I would advise you to calibrate a sensor with high-quality calibration equipment.
  • Practical module. Easy to use.

    A plug-and-play module that easily measures alcohol level exposure. Outputs both digital (Boolean) and Analog ranged output. Analog level can be used to measure scale of alcohol level in the air.Well build.
    Can be integrated very rapidly in arduino-like projects. Works best when alcohol is vented into/onto the sensor. Adjusts its levels back to normal within few seconds of exposure to fresh-air.
    Plug and play.
  • Excellent shower head with a few issues

    posted by CaptKirk

    Well built shower head. Very stylish and modern looking. Clean lines. Nozzles are the rubber type that are easy to clean and clear if they get clogged. The swivel is strong and well designed. The LEDS are bright and look very cool. I can leave the lights off in the bathroom as the shower head lights the shower now with free water power! The unit I received has 12 LEDs like (SKU: 117457). Temp sensing is fairly fast and seems reasonably accurate. The generator in the water stream is very quiet (for now).
    The price seems a bit high for getting plastic instead of glass. The overall quality is very good and it is impossible without touching to tell it is plastic so I will keep it. Time will tell if the generator stays as quiet over time as it is now.
    This (or actually SKU: 117457) is great if you like LEDs and water combined like me.
  • Easy to use, simple connection

    Easy to connect to an Arduino and sample from. Seems to be fairly well calibrated.A nice red LED to tell that there is power :-)
    Still dont know what long time use will do to the electronics when in a moist environment.It would have been nice if some sort of the output to moisture level had been supplyed.
    A very good product. I will be using a lot of these in my window farming project.
  • ROBOX IR Obstacle Avoidance Sensor Module

    - Looks just like the image advertised. - Very small and compact. - Easy to use, header pins just slide into the breadboard or a connector.
    Nice color added to the PCB.
    The item must be revised and a better description in the webpage. Looks like a solid build and if tweeked a little could be just perfect.My bottom is that there are cheaper ( price ) sensors boards out there and this one for is price is quite modest and effective.
