arduino digital sensor Customers Reviews

  • Good sensor, very accurate

    posted by ErKabi

    More accurate than the little brother DHT11. If you are interested in 0.5 degrees, this is your sensor. Works well with the arduino's DHT library (there is a library for the DHT11, another for the DHT22 and a library for both --> saves bytes in your sketchs). Works with 3.3Volts and 5V. The sensor works well. Only 3 wires: GND, GCC and the signal.
    None.
    You can meter the temperature in 0.5 steps.
  • Works great

    posted by Oxyacetylene

    Very good price for an Arduino sensor module. You can probably adjust the sensitivity but it may work fine without adjustment, depending on your needs.
    The "out" pin is normally in an on or high state. In your Arduino code you will need to monitor for that pin switching to a low state. You will probably want to also add a slight delay following the pin state read operation so it does not register multiple events every time it detects something...unless that is what you want.
    Great sensor module that works. Easy to use once you figure out the "out" pin as stated above.
  • Dallas DS18B20 sensor on a breadboard

    posted by Hendrik24051972

    This is a board with the Dallas DS18B20 temperature sensor on it, together with a pull-down resistor, and an LED.You get an "all-in-one" board, and there's no need to add more components. Everything you need to get it working is available on the print.
    I tape this kind of sensor to the heating pipes, and get very accurate temperature readings.
    Make your life easier, and get this print instead of the separate DS18B20 sensors.
  • Cool Gadget

    posted by rainerb

    Very easy to use. Just touch with your finger the circles to switch it on. This gadget is something else than just a mechanical switch. That is really the better alternative. Good quality of the printed circuit board. Works with 5V DC power. I tested it with arduino.
    Can be really used for very different projects. Just let your imagination work.
    Connect to power - and here we go. Enjoy.
  • Sensor de temperatura muy preciso

    posted by pyro329

    Este sensor de temperatura es por mucho mas preciso que el DTH11, se instala en segundos solo basta con conectar a la protoboard y de ahi al arduino alimentarlo con 5 voltios y es todo, ya esta listo para usar y mandar informacion a nuestro arduino
    Buena relacion costo/calidad
    Gran sensor de temperatura, debes de contemplar su compra si vas a comprar sensores para tu arduino.
