Gas monitoring device with an arduino

[Equinoxefr]

Hello,

I made a device to monitor my gas meter and report it to domoticz with a RFXcom. I'm using a few components: arduino, reed switch, DHT22 and a RF 433MHz transmitter.

You can find my project on github https://github.com/equinoxefr/gasMonitor









I plan to add a water meter too.

Cool!

How do you add it in Domoticz?
And i think you could also modify it to electricity, because the reedcontact works the same like a S0-connection? (close contact on pulse).

Hi,

It sends packet in RFXmeter (433MHz) format for the pulse sensor and oregon v2 for humidity / temp, so domoticz receive it with the RFXcom device every 30s.

For electricity i already have an OWL180 but you can do everything you want with an arduino

Hi,

I had some details of my domoticz setup (in french) on my web site http://www.equinoxefr.org/post/2015/01/ ... -domoticz/

Thank you for this

Hi,

I updated my code on github. Now you can disable use of DHT22 sensor.

Hello Pierre.

I got some probleme using your sensor

look at my graph and numbers, it can be true.

Hi,

Did you use serial debugging to check if the pulses are detected ?

Hi, can this be adapted to measure weight by using a pressure sensor such as this one:

I would like to monitor the weight of a water dispenser and have an alert/reminder when the water level is low.

Hello,

Question about RFLink. This is the module that you are using in this project: https://www.sparkfun.com/products/10534 ?

Because I was trying to use my FS1000A/XY-FST RF Radio but any RFX / RFLink device is recognized in Domoticz. (http://www.pocketmagic.net/using-fs1000 ... with-avrs/)
