I've not tested it, anyway according to the specs It should work. The Hydrosys4 SW interface includes a button for the sensor calibration which would be very useful for this types of sensors. Would be interesting get some feedback if anybody test it.
Regarding the Water Station, It's a little out of the scope for now :). Anyway I have to admit that I plan to add a Wind Sensor because it would be useful to monitor the wind when the Greenhouse windows are open. Accidentally I'm also thinking to use this system for automatic control of the awning in my terrace, but still a little out of scope for now :).
Thank you very much, this was clarifying. Do you know a PH sensor who would work with the system? If you also had a good wind and rain gauge, it would make a complete weather station.
The Automation Board has the following groups of connectors:
1) Connectors for the relay boards
2) Analog input connectors
3) I2C
4) GPIO
Point 1) This connectors are used to connect the relay boards, no much to say here. Specs of the relay boards are in the website hardware page (https://hydrosysblog.wordpress.com/hardware/)
Point 2) Analog inputs, (blue connectors in the image) are used to connect potentially any sensor which have analog output from 0 to 5 volts. Normally I use them with Soil moisture sensor, the following video provides some usage instructions: (https://www.youtube.com/watch?v=EZM3w_XAwQU&t=981s)
Point 3) I2C interface (white connectors). This interface can be used with the following sensors: The BH1750 for light and the BMP180 for the pressure. These sensors are quite easy to find and inexpensive. Many sensors have the I2C interface but only the two listed above can be used with the Hydrosys4 Software (current version 1.13). More sensors can be added to the SW in the future in case they I consider them useful for the project (Your feedback are welcome).
Point 4) The GPIO pins (red connectors). These are just connected to the Raspberry PGIO pins. Two of them are labelled with AM2302 and Servo1. The other are GPIO Pins shared with the relay connectors, so that specific GPIO cannot be used at same time for both relays and inputs. (GPIO labels are also indicated on the Relay contacts, so they can be easily checked). When shared GPIO are used as input, only 12 relays can be used instead of 16.
The AM2302 is a Air temperature and Humidity Sensor, the Servo1 can be used to connect a micro servo motor which I normally use to attach to the Camera to have shots at different angles. (https://hydrosysblog.wordpress.com/hardware/)
The two labelled pins (AM2302, Servo1) are anyway general purpose and can be used for other hardware connection, it will depend on the table on the HardwareSetting page.
Other hardware that can be connected to the GPIO pins:
hello, You can use the DS18B20, which normally comes waterproof.
You can have a look at the project hardware page:
I also remember there are other posts in this forum which speaks about it, you can make a quick search in this form.
Hello, I want to connect an outside weatherproof temperature sensor. Which one do you recommend and where to connect it?
Hi,
About the PH sensor, I've seen some that have analog Output like this one:

Other hardware that can be connected to the GPIO pins:
- Push Buttons (as in the irrigation HAT)
- Flow Sensor (https://www.youtube.com/watch?v=knE6Wkhxe4g&t=912s)
- Rain Sensor (on/off type)
- DS18B20 temperature sensor
- (Digital Soil moisture sensor, not available yet, but under testing)
The Hydrosys4 Software is very flexible and depending on the configuration of the HardwareSetting table, all the above can be managed.
Anyway for any specific configuration, just post here, I'll be happy to support.

Angelo
