Description: This tiny little guy is the ALS-PT19, an SMD ambient light sensor that is much smaller than the standard TEMT6000. The ALS-PT19 is capable of taking a voltage supply range of 2.5V to 5.5V and also functions as an NPN transistor. If you are looking for a small and easy to use light sensor, definitely pick up the ALS-PT19!

  • Throw it on the next gen redboards.

    • Oh yes! Or just an arrangement of a SMT loading resistor + 2 pads for you to solder this on yourself. ADC6/7 just cry out for any use at all. Other ideas include pads for a SMT thermistor (again, would require a loading resistor) or the TMP36 temperature sensor. I’m not saying to increase cost by $1 by populating them, but give us some pads that might turn out to be useful.

  • This part is very interesting, and will likely provide better specs that using an LED to measure ambient light. If you’re not familiar with that trick, see http://en.wikipedia.org/wiki/LED_circuit and scroll down to “LED as light sensor”. The LED trick is useful when you need to have both an LED and a rudimentary measurement of ambient response – and where the LED isn’t on constantly (e.g., using a form of pulse width modulation to control brightness, or just turns on the LED for a brief period after some event).

  • we will be including this on a few boards in the future.

    • Does that include a Breakout Board? I saw it is on the new Weather Shield.

      • nope, this is just for the bare IC. we might be doing a breakout. Really though, it’s just a much smaller version of several other we already carry.

  • Where is the eagle part for this?

  • Would this work with a laser?

    Thanks

  • Very nifty … and oh so very slow

  • The datasheet is white-on-white in evince. I wonder just how they managed to… pull that off.
