Inroduction
In this blog post, I am going to walk you through the hardware I am going to use for the Pi-ski-farmer which includes -
- Raspberry Pi 4(2GB version)
- Pimorini Enviro Hat
- Pimorini Automation Hat
- Pimorini Hacker shield
- Husky Lens
Raspberry Pi 4(2GB version)
There are already countless sources of information on getting to know the Raspberry Pi 4 on the internet. However, for sake of completion, I will cover that here.
The Raspberry Pi 4 is a single board computer for hobbyists and makers to quickly get to stead with using Linux for building embedded and IoT applications. It has a strong community base and is the established standard for Linux-based hardware in the electronics world. It is really easy-to use and offers enough computational power to do complex tasks like image processing. It has a multitude of interfaces like GPIO, display and audio ports along with Wifi and Bluetooth through which it can physically interact with almost every entity in the world of IoT.
If you want to know more you can find the entire list of specificitations here:
As can be seen clearly from the spec sheet it packs in lots of features into a board of this size. I am sure you are really excited to use it. I won`t reinvent the wheel here and would suggest you to go ahead and log on to

Pimorini Enviro Hat
It is a shield that mounts on top of the 40-pin Raspberry Pi GPIO header and provides a-
- Pressure Sensor BME280
- Temperature sensor
- Proximity sensor
- Light sensor
- Noise sensor
- An 96 colour LCD screen to display the readings
This is a pretty good resource on how to use this hat. https://learn.pimoroni.com/tutorial/sandyj/getting-started-with-enviro-plus
Crisp and clear - everything works as explained. Though it is for the Enviro+ shield it works for this hat also
Pimorini Automation Hat
The Automation hat allows us to interface external devices operated at up to 24V to the Raspberry Pi
NodeMCU
Husky Lens
Funduino Soil Moisture sensors
These sensors would be used to collect moisture data from various parts of my hanging garden and accordingly actuate the water sprayer
