    The seneye device can be used in the following ways. Online will give you constant uploads to with alerts. Offline will allow the device to work as a data logger and upload readings when the device is next connected to a PC using SCA.

    Using with a PC - online

    Connect your seneye directly to the PC. If your computer or laptop isn’t close enough you can extend the cable length by 2.5m using the seneye USB extension. For those who require even more range, the seneye active USB extension cable allows the cable length of the seneye device to be increased by an additional 15m. The seneye device can also be connected to a wireless USB bridge giving increased flexibility over Wi-Fi. You will however still need a PC running the SCA.

    Your PC you will need the following spec:
    PC with a wired or wireless network and TCP/IP protocol,
    Windows XP, Vista 32-/64-bit, Windows 7 32-/64bit, & Windows 8 32-/64bit.
    Full speed USB 1.0 port or higher
    Minimum 1Ghz processor and 128mb RAM
    HTML web browser: Internet Explorer 8.0+, Firefox 4.0+, Safari 4.0+ & Chrome.
    Internet connection (for setup and online use)


    Using with a Seneye Web Server (SWS) - online

    The SWS removes the need for any PC in the house and will connect your seneye to your internet router. It will then send results directly to the seneye cloud website. Visit for more information. With the SWS you can use a seneye device and an apple computer.

    If you are using your seneye with a Seneye Web Server please follow these instructions.

    Using in Data Logging Mode With A Power Adaptor - offline

    After initial set up, your seneye can be connected to a seneye USB power adapter. This option is great if you don’t wish to have your seneye device constantly connected to a PC. When powered by the USB Power Adaptor, readings are stored on the internal memory ever hour. Warning lights are displayed on the on the seneye device if the water parameters are bad. You will not receive alerts via SMS or Email.

    5. Registering your seneye slide

    Each seneye slide has a unique activation code which you must register to your seneye device. This allows us to ensure your device uses the correct ,maths for the slide type and batch.

    This link shows the ways to register your slide.

    You will need to do this with each new slide.


    6. Installing your seneye slide

    1. Remove the black plastic back cover from the seneye device.

    2. Take your pre-soaked slide and insert it into the device, taking care to hold it on the sides so the sensor areas are not touched. Ensure no air is trapped between the slide and device. This process is best carried out with the device under water.

    Tip: To ensure continuous and accurate readings for pH and ammonia, you should simply replace your seneye slide each month.


    7. Placing your seneye device

    Ensure that the drip protector is located on the end closest to your USB connector. The drip protector should be located at the lowest point on the cable. seneye device uses a washer to stop drips.PNG

    Your seneye device is designed to remain submerged. The seneye slide should not be allowed to dry out after intial soaking as this may give inaccurate readings. If your seneye slide does become damaged, please replace with a new one or contact [email protected] for more information.

    8. Aquarium use

    In an aquarium your seneye device should be attached using the supplied suction cup. Position the seneye device close to the filter or in an area of high flow to ensure sufficient water flow through the device.


    TIP: If the device is mounted to the back of the aquarium with the white face looking in, it could read out of water.  Make sure the back of the device looks into the aquarium.

    If you are using the light meter, then we recommend that you attach the seneye device to the front of your aquarium. If you wish to take precise light meter readings, use the light meter suspended below the water level pointing directly towards your aquarium lighting. This link explains more.

    9. Pond Use

    You can place your seneye device inside your pond filter or float it on the surface of your pond. If you are using your seneye device in the filter, then we would recommend that you position it so if you have a leak the seneye device will not remain submerged.  If your seneye device is connected to an internet enabled PC, you can choose to receive an alert if this happens.

    You can leave the seneye device floating in your pond. However if you would like to know if your pond has a leak, we suggest you teather the cable to the side of the pond so if the water level does drop the device is held out of water.

    TIP: Make sure no air is not trapped under the device otherwise it will indicate that it’s out of water. For this reason we recommend a postion with good flow but little aeration

    10. Seneye Connect Application SCA Offline Use
    If your SCA is not running please launch it now with your device connected to ensure that your readings are posted online.
    When the seneye device is connected to your computer and the SCA is launched, any stored readings will be automatically uploaded.  During this process egg timers may be shown,and live readings will not show until this process has finished. Do not unplug the device.
    If you wish to use the device offline, please disconnect the device only when the SCA has finished uploading readings. Graphs for these readings will be produced once they  have been received and analysed. Depending on the number of uploads this process can take a few minutes.

    The seneye logo circled above will show green if it can see our servers and red if it cannot.
    If you have an issue with it showing red please or data not going to please click here.
    12. Saltwater use 

    The seneye uses different maths depending on the ionic strength of the water and for this reason you will need to activate the use of the marine pH maths line to ensure the accuarcy. 

    Click this link to learn more on how to activate the marine maths.

    13. Seneye reef light meter

    The seneye reef adds a whole load of features to help you better understand the light in your aquarium. Light causes plant and algae growth so understanding it is of great importance.
