16 way capacitive Touch button sensor:
TTP229 Touch IC is a capacitive type Touch button keypad. This is a 16 switch based easy to use capacitive touch sensing module, This 16 switch digital touch sensor module is based on a touch sensing IV TTP229. This device has a built-in regulator for the touch sensor. We can add interfaces through the non-conductive dielectric material. The module has two working modes. An 8 Key mode that provides an independent 8 channel output. Another one is 16 key mode which provides 16 channel output with an I2C interface.
- Voltage range- 2.4V~5.5V
- Onboard power light
- Standby current- 2.5uA
- Modules, you can set the output mode, key output mode, the longest time and fast/low power output.
- Color- Blue
- Sampling rate- 8Hz and 64Hz
We also have normal telephonic keypad switch, have a look on it.
