  • Nice product for price

    posted by Henkisme

    Great product for the price! Worked great in some of my DIY projects. Very easy to use, simple digital output. Great product for beginners and also suitable for more advanced prototypers. Module is small enough to be easy to hide and a guarantee for fun projects.
    Would love to see a similar, flatter product for easier prototyping with breadboard.
    Very fun module and I definitely recommend buying this product for its easy of use and cheapness.
  • Very good Humidity sensor

    posted by pucheta

    * Cheap humidity sensor. Great price* Good for use with arduino or in another microcontroller circuit* Robust construction* Easy connect and to use
    * Too much time to arrive :(But maybe that is not fault of DX, is problem with courier.* I have tested the sensor and it seems to work fine. I connected to an arduino and i put the sensor in soil, then i watered the soil. The sensor (through arduino) showed me the changes in humidity value. Very good! :)
    Very good sensor at very good price.
  • okay

    FC-28-C Soil Moisture Detection Control Module + Soil Humidity Sensor - Blueproduct of excellent workmanship. packaged well. running perfectly.
    recommend to all. in site search easily think about the tutorial script to compile this function. It's a a great deal. The price is excellent for a original board and you. The shipment was fast, I got it within 1.5 weeks. It was packaged in a carton box within a bubble wrap envelop. No damage during shipment whatsoever.
    Good deal.
  • Simple to use, Narrow ranged, 2-way Light sensor.

    posted by RonaldoKass

    This sensor is very simple to use. Connect VCC (5V), GND and measure TTL high/low on the two digital outputs. Two trimpots allow you to configure the light sensitivity of each of the 2 channels, so that you can use that to measure two different levels of illumination.It is pretty well built.
    Make sure the light source (area) is facing the top of the photodiodes sphere (not the sides).
    Easy to use, narrow ranged.
  • High Quality Component!

    Small size. (less than 3/4 x 3/4 inches)Resistor onboard.3 pin interface. (GND,VCC,SENSOR)Includes holes for mounting and solder points for chaining other switches (in parallel)Super cheap!
    This is a very simple component.Great for use as a CNC limit switch.Has extra solder points for adding an LED.Switch is normally open.May need to twist/turn the magnetic switch to get it to activate properly when a magnet is place over the switch.
    If you are looking for an easy to use magnetic switch, you can't go wrong with this little board.
