## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=SEN0385:1` (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/SEN0385:1.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 an SHT31 Temperature & Humidity sensor housed in a weather-proof enclosure. The sensor is designed to be waterproof so you can use it safely in outdoor projects. Please note that although the sensor is waterproof, it is not suggested to submerge it in water. For in-water measurement, the [DS18B20 Sensor](https://www.dfrobot.com/product-1354.html) is highly recommended.

Thanks to Sensirion’s CMOSens® technology, highly integrated capacitive humidity sensing components, and band-gap temperature sensing components, the SHT31 offers high reliability and long-term stability with low power consumption, fast response, and strong anti-interference ability. The sensor supports I2C communication and is compatible with 3.3V/5V controllers like Arduino, micro: bit, ESP32.

SHT31 is the standard version of the SHT3x series. It provides humidity accuracy ± 2%RH@0% RH~100% RH (at 25°C), and temperature accuracy±0.2°C@ 0°C ~90°C (typical).
