LM393 Comparator Module Microcontroller Development Board Learning Board

APPLICATIONS:

Can meet a variety of resistive sensors (e.g. photoresistor, thermistor, etc.). The sensor sensitivity is adjustable. Standard XH2.54 interface.

Specification:
 

• Operating voltage: 3.3 V to 5 V.
• In the form of the output: analog output.
• b: digital output, the output threshold.
• Product Dimensions: 29.5 mm * 13.5 mm.
• Mounting Hole Size: φ3.

Usage:

1. The two rows of needle probe input interface, to meet a variety of resistive sensors (such as light-sensitive resistors, thermistors, etc.), 10 k pull divided voltage sensor input to the comparator internal, adjustable resistor voltage comparator inside regulatory negative input voltage, the compare output from the (positive terminal voltage is greater than the negative terminal, the output is 1, otherwise 0).

2. Output and SCM any IO port (according to the process definition) connected to detect changes in low levels through the microcontroller to detect changes in ambient brightness.

3. Analog output AO small plates can be connected to the input voltage acquisition
