## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=ADA5587:1` (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/ADA5587:1.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

If you're like me and have trouble keeping your calatheas and pepperomias happy and *not* overwatering them to root rot ruin, why not take a gander at the **Plant Monitor** from Ada-friend **[Monk Makes](https://monkmakes.com/pmon)**. Its a super easy and friendly way to get started with sensing & gardening projects with no soldering required.

This garden-stake-looking PCB gives you capacitive measurement of soil moisture. Capacitive measurements use only one probe, don't have any exposed metal, and don't introduce any DC currents into your plant friends and you wont get corroded contacts after a few months. Not only can it measure soil moisture but also temperature and relative humidity measurement.

It's compatible with the BBC micro:bit, Raspberry Pi, Pico, Pico W, and most microcontroller boards. Best used with boards that have alligator clip pads like the micro:bit.

- [Alligator / croc](https://core-electronics.com.au/search?q=alligator) clip rings
- Ready soldered header pins for your fav microcontroller
- Easy to use UART serial interface
- Additional analog output for moisture only
- Built-in RGB LED
