## Pricing

- **Price:** $53.70 (inc GST) — $48.82 AUD, exc GST
- **Quantity discounts:** 10+ $47.35 (exc GST) · 50+ $46.38 (exc GST)

## Availability & dispatch

- Out of stock — the product page offers email notification when it returns.

## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=ADA4099:1` (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/ADA4099:1.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

Take your next outdoor sensor project to the next level with this SHT-30 based temperature/humidity sensor. The sensor includes a dual-use sensor module from Sensirion in a sintered metal mesh encasing. The casing is weatherproof and will keep water from seeping into the body of the sensor and damaging it, but allows air to pass through so that it can measure the humidity outside. While it is designed to be submersible in water, it's always best to avoid long-term submersion (over 1 hour at a time), and it obviously would only give you temperature readings. For that, [Adafruit's metal-cased temperature sensors would be better](https://core-electronics.com.au/waterproof-ds18b20-digital-temperature-sensor-extras.html)! This sensor is best for simply placing outside for exterior weather sensing.

The **SHT30-D** sensor has an excellent ±2% relative humidity and ±0.5°C accuracy for most uses. [Unlike earlier SHT sensors](https://core-electronics.com.au/soil-temperature-moisture-sensor-sht10.html), this sensor has a true I2C interface.

The sensor is essentially just a Sensiron SHT-30 digital sensor ([much like Adafruit's breakout here](https://core-electronics.com.au/adafruit-sensiron-sht31-d-temperature-humidity-sensor-breakout.html)) with the 4 data/power wires brought out so any SHT-3x code for a microcontroller will work. [Check out the tutorial for Arduino and CircuitPython/Python, and more!](https://learn.adafruit.com/adafruit-sht31-d-temperature-and-humidity-sensor-breakout)

The 1 meter long cable has four wires: Brown = VCC (3-5VDC), Black = Ground, Yellow = Clock, Blue = Data.
