QT301 Features

* spread-spectrum burst modulation, permitting extremely high noise rejection characteristics for very robust signals even in high EMI environments. The device requires only a single sampling capacitor (Cs) to acquire signals. The value of this capacitor controls the gain of the sensor, and it can be
