Frequently Asked Questions


What makes it different from other aquaculture sensors?

About sensors: Osmo’s sensor is different than other sensors for two main reasons: price & maintenance. Unlike traditional continuous aquaculture sensors which use a number of individual selective ion sensors plugged into a sonde, OsmoBot’s sensor is optical-based. The core technology is built around photochemical sensor patches that change color or respond differently to light depending on the water quality conditions.

Instead of using a spectrometer which is an expensive and fragile piece of hardware to read these sensor patches, Osmo’s sensor reads the patches with a camera and custom algorithms. This approach has allowed Osmo Systems to reduce its sensor cost significantly compared to other aquaculture sensors and pass on those savings to you.

With dissolved oxygen, pH, and NH3 ammonia being read optically from a replaceable sensor cartridge, the system never needs to be manually recalibrated. Instead operators the system lets you know when it is time to exchange the sensor cartridge. Additionally, Osmobot uses its internal camera to detect biofouling on the cartridge and can let you know when the system needs cleaning.

These both eliminate the guessing that occurs with existing sensors when you encounter an unusual reading – is the sensor dirty, does it need recalibration, or is that reading actually accurate?

What are the specifications?

Sensor Specifications: Osmobot is built to be accurate well-within the tolerances necessary to run a shrimp or fish farm:

  • Dissolved Oxygen: +/- 0.3 mg/L (more precise at lower DO levels)
  • pH: +/- 0.3 (operational range is 6.5 – 9.5)
  • NH3: +/- 0.01 ppm (operational range from 0.01 ppm – 0.15 ppm)
  • Temperature: +/- 0.5ºC

We are constantly improving our algorithms and generally see even tighter tolerances than this, even though they are not required in aquaculture.

What happens if the power or internet goes out?

If an Osmobot loses contact with our server due to a power or internet loss, your system will alert you immediately that the connection has been lost so you can take action.

If the internet goes out, Osmobot will continue to collect data and will upload the data once the connection is restored.

What types of aquaculture systems does OsmoBot work for?

Ponds: Osmobot is built for fish and shrimp ponds, either coastal or inland. These are some of the most challenging systems to bring online historically and Osmobot is designed specifically to operate in such conditions.

Flow Through: Similarly, Osmobot is ideal for flow-through or partially recirculating systems that are not fully automated.

RAS: If you are operating an advanced recirculating aquaculture system, Osmobot is likely not the best sensing option for you yet. Given the unique nature of our sensor, it does not plug into a standard PLC and thus cannot yet be used in most SCADA systems.

Mariculture: While Osmobot is designed for land-based aquaculture, it can function in calm ocean-based systems. We generally find when we talk to ocean-based farmers, that pH and NH3 are not critical parameters and therefore Osmobot is not as useful, but please contact us if you are the exception!


Do I have to pay extra to use Osmo's software?

No: The software is included for free with your Osmo System.

Can Osmobot send me alerts when something goes wrong?

Yes: Generally, your Osmobot takes readings from your pond every 15 minutes and uploads them to the cloud.

On your account you can set who can get notifications when something goes wrong and in what format: app alert, email, or text.

In the future we will be looking to integrate with Whatsapp, WeChat, and Line for alert functions, as well.


How do I get a quote?

We are no longer building Osmobot so we cannot offer a quote.
