This module is used for amplifying signals that are too for the Arduino to read and because it is clearly labeled it is very user-friendly and is also very cheap, it is mainly used on the HB100 Doppler Radar Sensor because of its low voltage output, the doppler sensor’s voltage is a few millivolts, where this sensor times that with 100, this module alongside an Arduino can take 50mV and turn it into 5V but
