Description
Unlock the secrets of nature with code, engineering, and the
Kitronik Smart Greenhouse Kit for BBC micro:bit!
The Kitronik Smart Greenhouse Kit for the BBC micro:bit provides an exciting way to
learn about the relationship between plants and their environment. The user will learn
how to monitor environmental conditions and then how to build automated systems that
react to them. Grow a crop of plants with this smart greenhouse that can be coded to
monitor and automatically water them so that you can get them growing perfectly. This
kit is compatible with both the micro:bit V1 and the new microbit V2, available
separately.
The kit comprises a two-part plastic greenhouse, Kitronik environmental control board,
water pump, Kitronik ZIP Stick, and Mini Prong soils moisture sensor. Also included are
5 crocodile clips, ZIP extension cable and a small screwdriver. Just add a micro:bit,
seeds, and then some water and you will have everything you need!
The kit also ships with detailed assembly and coding instructions that will get you up
and cultivating in no time. There are also 7 online MakeCode tutorials that build in
complexity as you progress through them. They cover everything from gathering sensor
data and having the system automatically react to it, to visual user interfaces and more.
It is recommended that the user/student complete the tutorials in order for the best
learning experience.
At the heart of the micro:bit controlled Kitronik Smart Greenhouse Kit is the Kitronik
environmental control board. This board provides a variety of sensor inputs and
connection points for the BBC micro:bit (V1 & V2) and provides the ability to control
outputs for devices such as a water pump, fan, servo or heater pad. This makes it ideal
for feedback control systems, such as the smart greenhouse kit.
The environmental control board can be coded with the MakeCode editor and Kitronik
have produced a set of custom blocks to make the job as simple as possible. There are
blocks for reading input and for controlling additional devices such as a pump. This can
be added via the add Extensions function in the editor by searching “Kitronik” or
from https://github.com/KitronikLtd/pxt-kitronik-smart-greenhouse.
The default crop for these types of experiments is often cress, as it is quick growing,
requires little tending, and can be harvested when they are approximately 5cm tall
(within a few days). Cress is also practically a superfood, this alone could easily
become the subject of an entire lesson. Despite all of its benefits, cress is not the only
option. There are other sprouting plants, such as sprouting white mustard, which also
grows quickly and can be harvested when they are 5cm tall. You can also look into
micro-herbs/micro-greens, these too are usually ready to harvest within a week and
offer an excellent and aromatic alternative. Once you have chosen your preferred crop
type you then need to choose a suitable soil.
Note:
This kit does not come with a BBC micro:bit but will work with either a BBC micro:bit V1 or
a BBC micro:bit V2.
This kit is not waterproof. If you get the board wet, please turn off and allow to fully dry. Risk
of shock is very small, but please be cautious.
Due to electrolysis and being kept in a damp environment, the electrodes on the Mini Prong
Moisture Sensor will degrade slowly over time. Please see our general safety advice document
for more information.
Features:
Build automated growing systems that react to changeable environmental conditions with the
Kitronik Greenhouse Kit.
This kit is compatible with both micro:bit V1 and microbit V2.
The kit comes with detailed assembly and coding instructions.
At the heart of the kit is the kitronik Environmental control board that was specifically
designed to be the control hub for this kit.
Key features of the Environmental control board are;
o The board features a number of sensor inputs that can be coded to control the board's
outputs.
o There is an onboard BME 280 environmental temperature, barometric pressure and
humidity sensor and a separate Real-Time Clock (RTC).
o The board also features an onboard piezo buzzer, 2 1A outputs (ideal for a water pump,
heater pads or fan), 3 status ZIP LEDs, a ZIP LED expansion connector and servo output.
In addition to these, 3 BBC micro:bit pins are broken out to croc-clip connections as further
inputs and outputs, along with pads for 3V and GND.
o It can be powered via the onboard 3xAA battery holder or the 2.1mm DC Jack, and the
power controlled via the on/off switch with an adjacent LED indicator.
There are also 7 online MakeCode tutorials that introduce you to all of the features of the
board.
Crops such as cress, sprouting white mustard and micro-herbs/micro-greens are ideal for use
with this kit.
Code it with the MakeCode editor using the Kitronik custom code blocks for the
Environmental control board.
