  • Good and simple light sensor

    posted by Eridanos

    The sensor does what it supposed to do, measure the intensity of the light. I connected it on an analogue port of my arduino mega board and use a simple program.
    Sensitivity is mostly in the yellow red region of the light spectrum. Maybe I will put a neutral density filter to improve the linearity of the sensor.
    Bang for the buck to measure the light intensity on an arduino.
  • 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.
  • Perfect ffor a DiY project

    Suitable resistors are present on PCB.You just have to plug GND, 5V and to get the output.Embedded led is great to test in a standalone way.You do not need to be an expert to use it.
    Distance between LED and photo-transistor is 10mm.A good opto-interrupter. You just have to think where you can use it in your projects.
    I will certainly use it to count rpm in project where a motor will be involved.
  • Very robust and quality made sensor

    The Photosensitive Diode in this sensor is of a really quality, I get repatable results with the same light for different sites.The digital output can be near deactivated if you adjust enough the potenciometer. Mostly because if you only need the analog output (like my case) you will get the led turning on and off when no need at all.
    D0 is the Digital Output that can be used in any arduino pinA0 is the Analog Output that must be on the A0-5, for example if it is on A0 you must use analogRead(0) to get the value

  • Very easy to use

    posted by Cidde

    Really easy to use. Has both a digital and an analog output, which is really nice! The digital output threshold is controlled by a small screw.
    I'm using 12 sensors for a laser harp. I was a bit worried about latency, but the response time on the digital outputs is really fast - there's no noticable latency at all when using the digital output.
    There might be other options, but for me this worked perfect! The digital output was a winning argument when I bought this product.
