Product details

The LM393 Comparator Module features the LM393 dual comparator IC, designed to compare a reference threshold set by an onboard potentiometer with an external analog input. When the analog input exceeds or drops below the threshold, the module generates a clean digital logic output (HIGH/LOW). The module provides a stable and noise-filtered switching signal, making it ideal for precise edge detection and threshold-based measurements.

It also includes an indicator LED for visual detection and features high noise immunity, fast response time, and low power consumption. This module is commonly used in embedded electronics projects to interface analog sensors with digital controllers such as Arduino, ESP, STM, and other microcontrollers.
