1. Type of Sensor: Hall Effect Sensor
2. Model: 3144 (This is a common model number for Hall Effect Sensors)
3. Function: Hall sensors are used to detect the presence of a magnetic field. They are often employed for applications like motor control, position sensing, and speed detection.
4. Output: Digital signal (High or Low) indicating the presence or absence of a magnetic field.
5. Operating Voltage: Typically operates at 5V.
6. Connection Interface: Usually comes with three pins – VCC (power supply), GND (ground), and OUT (output).

LM393 Speed Sensor Module:

1. IC Used: LM393 (Comparator IC)
2. Function: This module is likely used for speed sensing or tachometer applications.
3. Output: Typically, the LM393 outputs a digital signal (High or Low) based on the comparison of two input voltages.
4. Operating Voltage: Typically operates at 5V.
5. Connection Interface: Commonly has three pins – VCC (power supply), GND (ground), and OUT (output). Some modules might have additional pins for fine-tuning sensitivity or other parameters.

Combined Setup:

If you are using these two modules together for motor speed sensing, the Hall sensor can be used to detect the magnetic field generated by a rotating magnet on the motor shaft, and the LM393 speed sensor module can process the signal and provide a digital output corresponding to the speed.
