## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=SEN0308:1` (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/SEN0308:1.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

This is a new type of analog capacitive soil moisture [sensor ](https://www.dfrobot.com/category-36.html)designed by DFRobot. Compared with the old [soil moisture sensor](https://www.dfrobot.com/product-1385.html), it has increased waterproof performance. Even if the sensor is fully immersed in water, it can still be used normally; the anti-corrosion performance is optimized and more Laminate design, no longer need to worry about the sensors in the soil scratching the sensor panel, resulting in accelerated corrosion of the sensor; the length of the electrode plate is increased and the circuit performance is optimized, the measurement range is expanded, and the measurement value of the sensor is more accurate!

In addition, the sensor still retains the built-in voltage regulator chip and supports a 3.3~5.5V wide voltage working environment, which means that 3.3V main control boards such as control, [micro:bit](https://www.dfrobot.com/topic-281.html), [ESP32](https://www.dfrobot.com/category-271.html), STM8/32 main control boards, etc. The sensor can still be used normally. On a mini PC like the [Raspberry Pi](https://core-electronics.com.au/raspberry-pi.html), you only need an external ADC to work properly.
