Digital I2S interface with high precision 24-bit data High signal to noise ratio is 61 dBA High sensitivity -26 dBFS Stable frequency response from 60 Hz to 15 kHz Low power consumption: low current consumption 1.4 mA High PSR: -75 dBFS
It is a bend sensor for hang gesture recognition. It is a type of variable resistor. The technology of this item is based on resistive carbon elements. It detects the gesture through variation in resistance value. Its resistance increases when a body of components bends. Its radius is smaller, so it gives a higher resistance value. Operating voltage: 0-5V…
