Capacitive touch sensing technology a wɔde aba no de nsɛnnennen ahorow ba ma ankasa-bere a wɔde di dwuma no. Nsusuwii a edidi so yi a ɛsɛ sɛ wosusuw ho no betumi aboa ma wɔatew parasitic capacitance so na ama nsateaa a ɛwɔ ahoɔden no akɔ soro, na awiei koraa no, ɛbɛma sensor design a eye.
Sensor Pad Size: Sɛ woreyɛ capacitive sensor a, sensor pad no nsusuwii nyɛ nea ɛho hia. Ade titiriw a ɛhaw adwene ne beae a pad no wɔ a ɛkyerɛ sɛnea ɛte no.
