Brief introduction of 1.KXTF9-2050

KXTF9-205is a kind of G-sensor, G-sensor (Gravity sensor), gravity sensor, also known as acceleration sensor (accelerometer), is a MEMS (micro-electromechanical system) sensor that can sense acceleration. Use I2C protocol to communicate with the host.

two。 Schematic diagram

(1) the power supply of gsensor is controlled by PWMTOUT3 pin. When the PWMTOUT3 output is low, the gsensor will not work without power; when the output power is high, the gsensor will work.

(2) SDA and SCL of gsensor are connected to I2C port 0 of S5PV210.
