    Is your sensor actually accurate?

    Is your sensor actually accurate?The short answer is it has to be or we won’t launch the product. Over the last year, the price of sensors has reduced and the tech advanced dramatically, but this doesn’t mean all the sensors you can buy today are accurate. Testing is key and currently, we are testing a large range of sensors thoroughly for a range of situations and uses.Do accurate sensor components exist now? Yup! But some are more expensive than others. Our approach is to focus on the sensors that work so you can rely on the data, always. Data first features second. Aside from the sensors, we are working extensively on creating a passively aerated case that allows for consistent and instant air movement for fast and accurate feedback from the immediate environment. Additionally, we will be sending the units for strict independent testing to confirm the above. We will make all test results public. Our team consists of professionals and perfectionists. If it isn’t reliable, it’s not for sale.We are not here to release another cheap, inaccurate iOT sensor, that promises the world but just gathers inaccurate data that can't be trusted or acted upon.If you have any specific questions reach out to us at

    What's in the box?

    You'll get the Grow Sensor, a USB charging cable and our quick connect operating manual. (All neatly packaged in a discreet box made from recycled cardboard to reduce our carbon footprint.)

    Where is the Grow Sensor made?

    We are still in the process of finalising manufacturers, but we plan for the Grow Sensor to be made in the UK.

    Will you ship outside Europe?

    Yup! The Grow Sensor will ship worldwide (subject to local/import taxes.)  We are already in discussions with distributors in Europe and the US.

    When will the Grow Sensor be available?

    We hope to ship our first Grow Sensors in the second third of 2021. Click any button on the site to join the waiting list and get notified of exciting developments!)

    Does the Grow Sensor have a warranty?

    Yup the Grow Sensor has a best in class 18 months warranty covering any manufacturing defects and/or hardware failures. What's not covered under warranty: accidental damage or unauthorised modifications.

    Does the Grow Sensor have a guarantee?

    Yup, it sure does! If you're not 100% happy with your Grow Sensor you can return it to us within 60 days for a full refund (excluding shipping costs.) Just make sure to send it back in it's original packaging with proof of purchase.

    How safe is my data?

    The safety of your data is our top priority. All information is encrypted with bank level security ensuring anonymity. We believe privacy rights matter and that will never change.

    Will you have an API?

    Yup, growers with the pro account can access our API and integrate the Grow Sensor with other equipment.

    What are you working on next?

    Alongside continuous ongoing improvements to the Grow App software, next up on the roadmap is a wireless soil probe that will measure EC, temperature and humidity.

    Is Grow Sensor suitable for mushroom cultivation?

    Yes it is! Our software and CO2 sensor are designed for mushroom cultivation. Growers will be able to analyse CO2 readings in grow rooms helping them to fine tune growing conditions and reduce the use of air extraction and therefore heating and humidifiers. We are big fans of growing mushrooms!

    How do I connect my sensor to my network?

    It only takes a minute to link the Grow Sensor to your network. Download the Grow App and turn on your sensor. Then click connect to sensor in the Grow App. The app will use your phone's Bluetooth to connect to the sensor, which in turn connects the device to the cloud via 2.4ghz Wi-Fi. Pretty much that simple.

    Are you a new company?

    New product, yes. New company, yes, but we’re not a new team. We've been in the tech industry for 20+ years and the electrical industry for 40+. We are a team of 5 who have a proven track record making digital and physical products. We are in this for the long run.

    Can I test The Grow Sensor for free?

    You certainly can if you plan to review the Grow Sensor. Drop us an email to and we will hook you up with a device to review.

    Can I preorder the Grow Sensor?

    If you're interested in pre-ordering now, drop us an email to: We will also add a pre-order service to our online shop in the coming weeks so check back in the future.
