Hardware

What are the dimensions of the air sensor?
2.95" x 0.77" or in metric 75mm x 19.5mm (diameter x height)
Temperature (F/C), Humidity (%), VPD (kPa) and Light (Visible/IR) on the Air Lite and Temperature, Humidity, VPD and CO2 on the Air CO2
The USB cord is 15 feet and the hanging kit is 10 feet
Grow spaces have different microclimates. Typically we recommend 1 sensor for spaces up to 25 square feet. The bigger your grow space, the more sensors you’ll need. Higher air flow means fewer sensors. Taller spaces or racks, on the other hand, means you need more sensors to have accurate data. In terms of hardware limitations, it's probably best to limit your router to around 50 units before you will see any performance issues.
Parameter readings are uploaded every 10 minutes automatically. If you'd like a real-time measurement simply press the right button on the sensor. You'll see a red flash followed by some green and white blinking. Check your app momentarily to see the readings.

Software

How many routers do you have? We recommend a max of 50 sensors per WiFi router for optimal service. If you need more than 10+ sensor we recommend giving us a call so that we can work with you for the optimal setup.
iPhone/iPad users can download the iOS app directly here. Android users can download the Android app from the Play Store directly here. If you prefer to use a desktop or a mobile internet browser, you can access the web dashboard here.
You can view your sensor data anywhere in the world with an internet connection on any device with internet capability. You can log on to your dashboard here.
You are in control of which alerts, if any, you receive. You can also send alerts to your email if you prefer not to receive alerts on your phone.

Privacy

What data do you store?
We collect and store your parameter data in order to show it to you. We will never share this information with anybody without your consent. Eventually, we have ambitions to anonymize the data in order to share it with the community so that everyone can learn more and compare their own parameters to other people growing the same crops.
We store your data in our secure and private AWS cloud. We always follow all best practices around the storing of information.
In order to access anything we need to access Mike's (he's a founder) eyeball everytime via the super secure eyeball reader that we bought on Amazon last year.
In all seriousness, we do take privacy and security to heart and follow best practices and use a variety of methods to keep your data secure and private.

Returns & Warranty

What is the return policy?
If you are not satisfied with your order for any reason, you may return it in its original condition within thirty (30) days of the original purchase and receive a full refund.
What is the warranty?
We offer a 1 year limited-warranty on the Air Sensor Lite. This covers all manufacturing defects and/or hardware failures. Our warranty doesn't cover damage caused by accidents or unauthorized modifications.

Other

What else are you coming out with?
We have plans for a lot of continual development of the Mendel platform from both a software and hardware perspective. In terms of hardware on the short list we just launched an Air Sensor with CO2 and after that we plan to work on a soil sensor, smart lights, water sensor and outlet control in no particular order.
Do you ship internationally?
Yes! We ship globally. One thing to note though is that the Mendel Air Sensor comes with a 2 prong US/North American AC/DC adapter, so you will need to find the appropriate USB adapter for use in your home country. For international orders the cost of shipping only includes freight charges from our warehouse to your location.
