    Hi,
    There is option to connect 2 sensors for OSPi:
    1. Rain Sensor (Then when it rainy day, and the water is open, it will close automate)
    2. Land Sensor (That in computer I see when the land is dry).

    Regards.

    1. rain sensor is already supported.
    2. land sensor: i’ve never seen a land sensor, but it’s certainly possible to add support for it. first you need to figure out if the land sensor is a digital (i.e. on or off) or analog sensor (i.e. continuous level of voltage output). if digital, it works just like a rain sensor, and you can use any of the spare GPIO pins to interface with the sensor. if analog, you can use one of the analog (ADC) pins on OSPi to talk to the sensor. The hardware connection should be pretty easy once you decide which pin you want to use. then you also need to modify the source code to add support. if it’s a digital sensor, you can pretty much copy what’s already there for the rain sensor.

    Please you can give any rain sensor for example ?
    The land senor, I mean like “Edyn” from kickstarter. (To see if my land is dry and open the water)

    Regards.

    Search ‘rain sensor’ on Amazon and you will see plenty of options. The one I am using is this:

    Great, what about the land sensor ?
    Also Flow sensor ?
    Can I connect all these sensors with Valves?

    Regards.

    Land sensor and flow sensor are not supported in the firmware. You will need to modify the source code to add support. For flow sensor, search the forum and you will find a few threads where people have discussed how to add it.

    Another 2 questions please:
    1. To connect the RPi, I need also to connect MicroUSB or the 24V transporter is enough ?
    2. Can I use Heatsticks with the OpenSprinkler Board? (or it will not fit?)

    Regards.

    1. The 24V transformer is all you need. The OSPi board provides power to the Pi via the GPIO pins.
    2. Heatsinks should fit the Raspberry Pi sits on top of the OSPi.

    Can I control Opensprinkler Pi when I didn’t on my local internet ?
    Like from other place in world (for example)?

    Regards.

    Yup, you can set up port forwarding on your router.

    I have reviewed the photos and video of the Pi model but do not see where the rain sensor connects.

    Are the photos old? Or did I just not see it? Or have I mis-understood this thread?

    You should check the latest user manual:
    http://rayshobby.net/docs/ospi14_manual.pdf
    page 6, ‘Rain Sensor’ section. Rain sensor port has been added since OSPi 1.3. The video is outdated and I should re-make it at some point.

    Hi,

    I’m not sure how to interpret this.

    Rain sensor port has been added since OSPi 1.2.

    I have 1.2 version can I use the rain sensor?
    I tried to search in the manual for the 1.2 version but didn’t find anything.

    In the picture below, the rain sensor input can be seen. It is the green two wire connector on the right of the device. On the far left are two connectors for the common return wire and the 8 way connector in the center is the 8 zone output block. On the left side of the case you will see the orange power input connector and out of view on the rught side is an 8 pin expansion connector.

    The rain sensor may be either normally open or normally closed and this setting is changeable via the software.

    On the latest version v1.4 the opening panel in the center of the case is blocked off but is still visible. It severs no purpose on the OSPi.

    Hi,

    Isn’t that the connector for extension boards in version 1.2?

    Sorry about the big picture link…
    Not sure how to use this feature…
