## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=PIM533:1` (comma-separated SKU:qty pairs) and share the link. Opening it shows a confirmation page with live pricing and stock before anything is added to the cart.
- **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/PIM533:1.md` for live line prices (inc & exc GST, quantity discounts applied), stock and dispatch estimates, and totals. Append `/to/{AU-postcode}` (or `/to/{country-code}:{postcode}`) before `.md` for delivery options and prices to that destination. Unknown, retired, or out-of-stock SKUs are flagged. (Query form `cart/link.md?items=...` also works but some robots parsers refuse query strings here.)
- **Checkout** is completed on-site and includes a captcha at the payment step. Share the cart link; checkout takes it from there.
- **Search the catalogue:** `https://core-electronics.com.au/search/{query}.md` (URL-encode the query; pages 2-3 at `search/{query}/{page}.md`; `search.md?q=` also works)

## Description

A Raspberry Pi mini HAT designed to help you take care of your plants. It can tell you how well they're hydrated, attract your attention when they need water and, if you want to go a step further, even give them water!

Please note that **this listing is for the Grow HAT Mini HAT only**. You'll probably want [some moisture sensors](https://core-electronics.com.au/grow-moisture-sensors-pack-of-3-1.html) as well - and don't forget [some cables](https://core-electronics.com.au/jst-sh-3-pin-connector-for-grow-moisture-sensor-pack-of-3-1.html)!

**Automatic, systematic and hydromatic!**

The heart of this clever system is the **Grow HAT Mini**. This Raspberry Pi Mini HAT has a tiny screen to keep an eye on the state of the system, four tactile buttons for navigation and an on-board piezo buzzer to politely request your attention when your plants need you. There's also a light sensor, which Pimoroni has used in our code example to stop the alarm from chirping away at night. Pimoroni has covered the PCB in little gold flowers, because we love you. 🌻

There are three connectors on board to attach our **capacitive moisture sensors (sold separately)** so you can measure the moisture levels in three separate pots. Because there are no exposed electrodes, capacitive sensors are a lot less vulnerable to corrosion over time than old school resistive sensors. They even have a little area so you can label them with plant names (we think 'Pete' is a great plant name).

On the back of the Grow HAT Mini there are another three connectors that will let you turn low-current 5v devices on and off, like pumps, motors, valves, solenoids or lights. There's also a set of broken out I2C connections, perfect for adding on an I2C breakout (like those in [our Breakout Garden range](https://core-electronics.com.au/collections/breakout-garden?stock=true)). Being able to add on more sensors and interface with extra devices means that it's possible to level up your budding Grow system to something much more capable and sophisticated - a proper little **smart greenhouse for your desktop** (or your spaceship, classroom or apocalyptic bunker!)

**Software**

As well as the usual examples in the [Python library](https://github.com/pimoroni/grow-python) to show you how the individual bits of hardware work, Pimoroni has also put together a full **plant monitor application** so you can start taking care of your plants straight away. Pimoroni has even managed to fit a little UI in there, so you can change your settings directly from the HAT.
