Domoticz

anyone willing to accept the challenge to add code for PH / EC / DO / NH4 & NO3 Probes ?

ie) https://www.sparkfun.com/categories/146

as I am sure most homes have Aquariums end users might want to data log and have alert notifications for ?

willing to donate

Already wrote code to support the Seneye Aquarium monitor

thanks but I consider those as a fake system

its a spectrometer that guesses based on colour / temp formula I looked into those a few years ago

most of the digital probes use I2C interface but the code does not seem to have many of the devices added
it does seem to support 8bit expanders but my probes are 12 bit

I did (untill this week) monitored the temperature with a waterproof temp sensor connected to MYSensors.
I also have a DHT22 in the bathroom which i am going to replace with a Sonoff th16 with a AM2301 which is also a DHT hum and temp sensor.
I just ordered another Sonoff TH16 with the waterproof temp sensor.
This one is going in to the water again.

I already have mysensors temp and pH probes in my aquariums. Would he very interested on NH4 and NO3. Do appropriate probes and sensors exist that can be hooked to an Arduino (at a reasonable price of course) ?

the NH4 and NO3 probes I know of are over $1k ea

their are short term ones for $100 , but not for long term submersion

ideally looking for something that can be built using Spectrometry but that is a project on another forum

just a matter of finding opensource

but for now i just want these sensors supported

Both the ORP and dissolved O2 sensors provide the option to use UART mode in addition to I2C. The manufacturer provides all the required information about both protocols and even provides some sample code, but doesn't seem to provide a suitable arduino library.

Searching through the inet I found the following which you could use as a base:

I also found other similar projects for the DO and pH sensors, so it shouldn't be too difficult to write your own version for your project.

For pH, the sensor you point to seems to require and additional interface. The same manufacturer seems to provide another option using a standard probe with a BNC connector:

Another option is using the following breakout board, which is widely used with arduino:

Another varation:

I hope this helps.

Can confirm mysensors + arduino zero works good.
Had only a groundloop problem with pH, but using a i2c adc and i2c / 5v isolator, it works like a charm, very steady.
Output to 4 ledstrips and input from 2 flowmeters, pH sensor and ds18b20 temp sensor;

Hi,

I'm looking for a solution to have the pH value on my domoticz.
I have a gateway MySensors.
Someone to help me please ?

Thank you.
