Capacitance-type Sensor
AIN2 (PIN 5) and AIN3 (PIN 7) are designed to support capacitance-type sensors. In default
GV200 only support capacitance-type sensors which voltage range is 0 ~ 2.7V. If user wants
to use the capacitance-type sensors which voltage range is out of 0 ~ 2.7V, a level transfer
board must be used between capacitance-type sensors and GV200. The follow figure is the
example connection of AIN2/3 with capacitance-type sensors.

User also can connect a power source directly to AIN2/3, the voltage limitation is same as
capacitance-type sensor.
