## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=ADA5964:1` (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/ADA5964:1.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

Now you can quickly integrate the [Sensirion SEN54 / SEN55 environmental sensor node](https://blog.adafruit.com/2022/02/10/eye-on-npi-sen54-environmental-sensor-node-eyeonnpi-digikey-digikey-adafruit-sensirion/) into your microcontroller or microcomputer project, with no soldering or fiddly breadboarding - thanks to this here **Adafruit SEN54 or SEN55 Adapter Breakout**. Adafruit covered the awesome [Sensirion SEN54 / SEN55 environmental sensor nodes on EYE ON NPI](https://blog.adafruit.com/2022/02/10/eye-on-npi-sen54-environmental-sensor-node-eyeonnpi-digikey-digikey-adafruit-sensirion/) a while ago, it's an awesome all-in-one air quality sensor, but has the annoyance that it requires 5V power and it has a special cable connection.

This adapter breakout will make an instant friendship with all SEN5x boards, thanks to a JST GH-compatible connector in the middle so that you can plug a [6-pin GH cable](https://core-electronics.com.au/jst-gh-125mm-pitch-6-pin-cable-100mm-long.html) directly between your SEN and this adapter. In the middle is a small switch-cap boost converter that will generate 5V at 100mA to power the fan and electronics in the SEN5x even if you're using 3V power and logic. [Then you can use any ol' STEMMA QT cable](https://core-electronics.com.au/jst-sh-4-pin-cable-qwiic-compatible-100mm-long.html) to plug into your Metro, Feather, QT Py, Raspberry Pi, etc etc. I2C port.

Once you've got it plugged together, you can run Sensirion's [Arduino library](https://github.com/Sensirion/arduino-i2c-sen5x) or [Raspberry Pi Python library](https://github.com/Sensirion/python-i2c-sen5x) to read temperature, humidity, VOC, Particulate Matter PM1 / PM2.5 / PM4 and PM10. (NOx reading is also available on the SEN55)

**Please note: this board does NOT come with a JST GH-compatible cable NOR a SEN5x sensor!** You [can pick up the cable here](https://core-electronics.com.au/jst-gh-125mm-pitch-6-pin-cable-100mm-long.html), and [a SEN5x here](https://core-electronics.com.au/sensirion-particle-voc-humidity-and-temperature-sensor-sen55.html).
