## Pricing

- **Price:** $23.80 (inc GST) — $21.64 AUD, exc GST
- **Quantity discounts:** 6+ $20.55 (exc GST) · 12+ $19.69 (exc GST)

## Availability & dispatch

- Available with a lead time — expect dispatch between Aug 21 and Aug 25.

## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=SEN0315:1` (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/SEN0315:1.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

Build an awesome interactive project with this PAJ7620U2 [Gesture Sensor](https://www.dfrobot.com/search-Gesture%20Sensor.html)! It is an interactive sensor with 3D gesture recognition that can recognize 13 gestures at most within 20cm. The sensor offers stable performance, fast response and high accuracy, which makes it an excellent choice for interactive applications like non-contact remote controller, interactive robot, gesture-based game device, smart lighting management, and so on.

There are two recognition modes for this sensor: fast mode (9 gestures) and slow mode (13 gestures). In fast detection mode, the sensor can recognize 9 gestures: move left, right, up, down, forward, backward, clockwise, counter-clockwise, wave.The slow mode can recognize 4 expanded gestures besides the 9 basic ones: slowly move left and right, slowly move up and down, slowly move forward and backward, move randomly. The unit sampling time can be defined by users in this mode. Moreover, users can customize their own gestures if necessary.

###  Projects

Project 1: [**Gesture Universal Remote-control**](https://www.dfrobot.com/blog-1500.html)

With this remote control, we can control the electrical device by gestures. It also includes custom features, so it is theoretically possible to control all the electrical appliances controlled by the infrared remote control.
