## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=ADA576:1` (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/ADA576:1.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

Put a temperature meter anywhere with this very handy display. This panel meter displays the temperature of the attached waterproof 1% thermistor in °C. It does require a DC voltage to run, at 4.5-30VDC. It has reverse polarity protection in case you swap the power leads by accident.
 
 To use, simply connect the thin red wire to a positive supply, and the thin black wire to ground. Then tape the black thermistor bulb to whatever you want to measure - or leave it loose to measure ambient temperature. The display has a microcontroller that will read thermistor resistance and display the corresponding temperature from -30°C to 70°C with 1 °C precision on a 3-digit 0.56" tall 7-segment display. The meter draws 3-4mA to power the microcontroller and display. This particular LED display is a nice vivid blue, which Adafruit found very readable. To mount to your enclosure, simply cut a 45.5mm × 26.5mm rectangle and snap it in.
 
 **This meter can only display the temperature in Centigrade °C, it cannot be modified to °F and we do not have a version that is °F.**
