#150915 - Technical Details on Capacitive sensing Responding to: ???'s previous message |
Suresh,
For serious capacitive touch without calibration and smart (micro) algorithms. You won't get a reliable result... Read up on the Cypress CapSense and Analog Devices Capacitive button sensing...... there are a lot of factors that need to be considered for a reliable design. http://www.analog.com/en/conten...%2C00.html http://www.cypress.com/capsense/?app=6 Joe |

| most un reliable - is this a commercial product | 01/01/70 00:00 | |
| for commercial product only.. | 01/01/70 00:00 | |
| why its considered unreliable | 01/01/70 00:00 | |
