GV200G User Manual
Capacitance-type Sensor
3.3.10.2.
AIN2 (PIN 5) and AIN3 (PIN 7) are designed to support capacitance-type sensors. In default
GV200G 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 GV200G. 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.
