DescriptionAdd lots of touch sensors to your next microcontroller project with this easy-to-use capacitive touch sensor board. This chip can handle up individual touch pads. Using this chip is a lot easier than doing the capacitive sensing with analog inputs, it handles all the filtering for you and can be configured for more/less sensitivity. Features- Color: Blue.- Material: Power module.- Size: 2.00 x 1.50 x 1.00cm/ 0.79 x 0.59 x 0.39 inch.- Supply voltage: 2.5-5.5V.- This module is based on a touch detection IC of capacitive type touch jog switch module. - Stable touching detection of human body for replacing traditional direct switch key.- A very useful addition for projects or applications where a conventional mechanical button or switch is not an choice.- The module can be installed in plastic, glass surface non-metallic materials. - As long as the touch of the correct position, you can make hidden in the wall, desk and other places. Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement.
