In this article number: 82649264 ?
(P.S, the red wire goes to Output pin 7 instead of 5V on the PiFace in your schematic)
Try this one: http://r.ebay.com/Ox4XvE I just ordered a couple.bistoury wrote:Hi remb0 ! Can you pleade detail that piece of hardware that you connect to your piface (brand, référence, supplier cost...).

Yes these TCRT5000 sensors work very well (glued on my powermeter and also gasmeter).Ritmeester wrote:Try this one: http://r.ebay.com/Ox4XvE I just ordered a couple.bistoury wrote:Hi remb0 !

Analog and Digital output. $1.75 = € 1,27 including shipping.
Try to find another seller. There are more sellers who sell this and ship to France.bistoury wrote:Hummmm.... Now ebay is bloc king me due to country restrictions (i am inFrance)
I will use Heatshrink (Krimpkous) to safe it. Only the LED’s notRaspberry Piet wrote: Cause i doubt this TCRT5000 sensor will work foolproof for long time when it is in a humid area under the floor where my watermeter is.
Still then... when the glass is moist the IR light will dissipate and the sensor couldn't work properly <= Did not test this so maybe just in theory.Ritmeester wrote:I will use Heatshrink (Krimpkous) to safe it.

Yes, It can work because on your 8 outputs are normally 3.9 Volt between the Input Block (0V-GND) and de Output Block (5V) You can’t use that Output port anymore for something else. I rather choose for the 5V on the Output Block.remb0 wrote:don't know why but I have this als my schema. but it works.

I've got the same sensor but how did you connect it to the raspberry pi?bizziebis wrote:Bought this sensor from Ebay: http://bit.ly/RawnMy
It's working but it is hard to position it to work right.
How/where did you guys mount the sensor?
I'll post a picture of my mounted sensor later tomorrow.
I've edited the database to match the real watermeter usage. So in a couple of days I can see how reliable the sensor is. To be continued...
Output 5 volt will blow up input ports right?Ritmeester wrote:Yes, It can work because on your 8 outputs are normally 3.9 Volt between the Input Block (0V-GND) and de Output Block (5V) You can’t use that Output port anymore for something else.
