Description
The LM393 amplifier module can be used to compare an input voltage with a predetermined voltage level. The LM393 IC contains 2 op-amps that are completely independent. In LM393 comparator module, only one of the op-amps is used and the other is not connected. The module compares input voltage with the desired voltage level, and produces a digital output. The voltage level can be any value between the module positive and negative supply voltages. This voltage level can be adjusted using the potentiometer on the module.
