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/CE06251:1.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) - **Payment methods, purchase orders, policies and contact details:** https://core-electronics.com.au/llms.txt ## Description The Prong soil moisture sensor for [BBC microbit](https://core-electronics.com.au/micro-bit-v2-australia.html) is a sensor board that can be directly mounted to a BBC micro:bit to monitor the moisture present in soil. The two conductive tines are placed into the soil. Any water or moisture in the soil will conduct to give an analogue voltage that can be read by the BBC micro:bit. Prong is powered from the 3V supply of the BBC micro:bit. Use either the USB or JST connector on the BBC micro:bit to power the circuit. Prong and the BBC micro:bit can also be powered from the Mi:Power board to create a compact stand alone unit. The board has been designed so that the BBC micro:bit can be bolted on using 3 x M3 nuts and 3 x M3 screws. Place the screws through the P1, 3V and GND holes of the PCB and BBC micro:bit, then use the M3 nuts to fasten together on the back of BBC micro:bit. Alternatively croc-clips can be used to connect between the Prong and the BBC micro:bit. If using the Mi:Power board then additionally connecting P0 means the BBC micro:bit can sound an alarm if the soil becomes too dry. When fitted to the Prong moisture sensor, the micro:bit can be coded via any of the micro:bit editors, such as the Microsoft [MakeCode editor](https://makecode.microbit.org/). *Note: To ensure that the Prong moisture sensor has a long and fulfilling life, it is better to write your code to perform a moisture check every so often rather than continuously. When the check is performed continuously it promotes rapid erosion of the electrodes.* **Features** - Works with both the Micro:Bit V1 and [Micro:Bit V2](https://core-electronics.com.au/micro-bit-v2-australia.html) - Measure soil moisture levels. - Attaches directly to the microbit. - Use in conjunction with the Mi:Power board to provide power and an audible alarm. - Code with any microbit coding editor. **Contains** - 1 x Prong Soil Moisture Sensor for microbit. - 3 x M3 Hex Nuts. - 3 x M3 Countersunk Screws. **Dimensions** - Length: 68mm. - Height: 53mm. - PCB Thickness: 1.6mm. **Requires** - 1 x [BBC micro:bit.](https://core-electronics.com.au/micro-bit-v2-australia.html) **Resources** - [Datasheet](https://core-electronics.com.au/attachments/localcontent/5647-prongmoisture-sensor-microbit-datasheet_295709186d3.pdf) ## Images - [Product image 1](https://core-electronics.com.au/media/catalog/product/5/6/5647_large-prong-moisture-sensor-microbit_800x.jpg)
