Are you tired of clicking a mechanical button? Try our capacitive touch sensor. Right now we can find touch sensors on most electronic devices. So upgrade your Arduino project with our new version touch sensor and make it cool!!

## Pricing

- **Price:** $5.70 (inc GST) — $5.18 AUD, exc GST
- **Quantity discounts:** 6+ $4.93 (exc GST) · 12+ $4.72 (exc GST)

## Availability & dispatch

- In stock, ships same business day if ordered before 2PM (Australia/Sydney).
- We can dispatch 6 today, and up to 400 more in 8–12 days.

## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=DFR0030:1` (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/DFR0030:1.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 compact capacitive touch sensor can detect the presence of people, providing a high or low voltage signal in response. It remains effective even when covered by materials like cloth or paper, though its sensitivity will diminish as the covering becomes thicker. ![](https://core-electronics.com.au/media/remote_images/touch1_Bxrfop.jpg) With this sensor, an Arduino can feel your touch ![](https://core-electronics.com.au/media/remote_images/touch2_2UStEN.jpg)
