Need to sense touched part on a screen with well-proven technology? The Grove Touch Sensor v1.1 is an ideal product for you. It enables you to replace the press with touch. It comes with an LED to indicate the touch. Using the TTP223-B touch detector IC, it measures the capacitance of a metallic pad and detects the change in capacitance when a finger is touched near it, so you can place the metallic pad under a non-metallic surface such as a plastic or glass sheet and it will work as a button. This is the same technology used in the touch screens of iPhones.

This sensor can be useful for projects that need to be kept as waterproof. By carefully positioning, you can make this touch sensor totally unnoticeable and you can protect it by special materials too. You can also make a secret button by placing this sensor in an unnoticeable manner behind a smooth surface. You can place it as per your design requirements, for instance, under a non-metallic table. By casually pressing the right location on a tabletop surface, you can mysteriously control your DIY projects. Isnt it amazing?

As always with Grove modules, this touch sensor is easy to connect to your Grove board and is connected to one of the input ports on your Arduino using a cable (not supplied). No need for soldering, its both quick and reliable! For all Grove users (especially beginners), Seeed Studio provides guidance PDF documents. Please download and read through Preface Getting Started and Introduction to Grove before using the product. This is a suitable product for not only Grove users but also all electronic enthusiasts. So, why wait? Buy now!
