Watermeter with wireless door sensor and TCRT5000 ?

I use a wireless doorsensor on my gasmeter like the KAKU wireless doorsensor project, and it works very well.

Now i would like to monitor my water meter with a TCRT5000, but do not want to use piface or raspberry gpio.
Would it be possible to use one of my wireless doorsensors, remove the reed contact and attach the digital or analog output of the TCRT5000 to these contacts ?

The removed reed contact just makes connection between the two contacts, is the TCRT5000 usable to replace the reed contact ?
This setup would make a very cheap wireless watermeter counter.

Thanks

Why not connect this sensor directly to GPIO pins 3,3v / GND & GPIO? Instructions are available on the forum ;-)

Because i am not using my raspberry for domoticz, only as xbmc media player. I run domoticz on my ubuntu server.

Clear in that case it is an interesting setup :)

Interesting looking for such a solution as well, did you succeed, can you share some pictures and the script you used?

You could also build this with MySensors: http://www.mysensors.org/build/pulse_water

Build an Ethernet gateway (Arduino + W5100 Ethernetshield) or Serial gateway (Arduino connected with USB to your server) and receive the data from the watermeter node (another Arduino, but this one measures the watermeter with TCRT5000).

The needed parts can be obtained cheaply from China, by buying from eBay or so.

MySensors is supported since a few weeks ago, in the beta release of Domoticz.

I'm interested too in a cheap (preferably ready-to-use) solution for logging the water-usage. Maybe, in due time, there will be something I can use for my watermeter.

TCRT 5000 can be used for watemeter just fine.
I would not suggest to use the interrupt routines. It gave me a lot of false positives in the beginning.

What would one advice for metering the water usage with a meter like this:

I know there are ready-to-use solutions, but they cost about 80 euro's and for that amount of money I can use a lot of water... So I prefer a cheaper way to monitor the usage and.....something that is easy to make for a n00b as me :D

mvveelen,

I'm working on a TCRT5000, directly connected to GPIO.
It detects the metalpart of the arrow.
Now I have to change the it, so it only sends a puls to my domoticz when the status changes from 0V to 3.3V.

Will that work flawlessly, or is this perhaps a better way: http://www.domoticz.com/forum/viewtopic ... 1103#p6746 ?
That might even be easier to build or mount to the water meter, wouldn't it?

Not sure, I made a small Python script to detect a one rotation. That is working fine now.
Next step is to upload the "puls"to domoticz. Since I running domoticz on Ubuntu VMware session.

tcrt-5000 will do just fine with this meter.

Would the TCRT5000 work with this type of water meters?

Hmm , Probably not as there is not a lot of reflective area the sensor can use
