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/SEN0563:1.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) - **Payment methods, purchase orders, policies and contact details:** https://core-electronics.com.au/llms.txt ## Description Fermion: MEMS Formaldehyde HCHO Gas Detection Sensor employs state-of-the-art micro-electromechanical system (MEMS) technology, endowing the sensor with compact dimensions (13x13x2.5mm), low power consumption (<20mA), minimal heat generation, short preheating time, and swift response recovery. This sensor qualitatively measures the concentration of formaldehyde gas, making it suitable for applications in air purifiers, HVAC systems, smart wearables, portable detectors, and more. The MEMS series currently encompasses 11 different types of gas sensors ([HCHO](https://core-electronics.com.au/fermion-mems-formaldehyde-hcho-gas-detection-sensor-breakout-0-3ppm.html), [CO](https://core-electronics.com.au/fermion-mems-carbon-monoxide-co-gas-detection-sensor-breakout-5-5000ppm.html), [CH4](https://core-electronics.com.au/fermion-mems-methane-ch4-gas-detection-sensor-breakout-1-10000ppm.html), [VOC](https://core-electronics.com.au/fermion-mems-volatile-organic-compounds-voc-gas-detection-sensor-breakout-1-500ppm.html), [NH3](https://core-electronics.com.au/fermion-mems-ammonia-nh3-gas-detection-sensor-breakout-1-300ppm.html), [H2S](https://core-electronics.com.au/fermion-mems-hydrogen-sulfide-h2s-gas-detection-sensor-breakout-05-50ppm.html), [EtOH](https://core-electronics.com.au/fermion-mems-ethanol-etoh-gas-detection-sensor-breakout-1-500ppm.html), [Smoke](https://core-electronics.com.au/fermion-mems-smoke-gas-detection-sensor-breakout-10-1000ppm.html), [Odor](https://core-electronics.com.au/fermion-mems-odor-smell-gas-detection-sensor-breakout-05-50ppm.html), [H2](https://core-electronics.com.au/fermion-mems-hydrogen-h2-gas-detection-sensor-breakout-01-1000ppm.html), [NO2](https://core-electronics.com.au/fermion-mems-nitrogen-dioxide-no2-gas-detection-sensor-breakout-01-10ppm.html)), which can be combined as per specific requirements. **Please note:** This sensor is capable of only qualitative measurements.
