This is the TTP223B based touch sensor module which can detect a human finger touching it. This allows you to replace those mechanical switches that have been holding back your project all this time.When touched the module will drive the signal HIGH and put itself into touch mode. If not touched in the following 12 seconds the module will enter a low power mode which will increase the response time to 220mS but greatly reduce the power consumption. When in touch mode the module will have a speedy 60mS response time.As a simple module it will suit use within a large range of projects based on microcontrollers such as Arduino boards and the Raspberry Pi. The module has a pair of M3 mounting holes allowing for its easy attachment to a multitude of surfaces.
