LM393 Comparator Module Comparing Module MCU Development Board Learning Board
1). The sensor sensitivity adjustable.
2). Angle processing user-friendly design.
3) standard XH2.54 interface.
You can meet a variety of resistive sensors (e.g., photosensitive resistors, thermistors, etc.).
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.
1. Two rows of needle probe input interfaces to meet a variety of resistive sensors (such as light-sensitive resistors, thermistors, etc.), 10 k internal pull on the divided voltage sensor input to the comparator, adjustable resistor voltage comparator negative internal controls input voltage, the compare output from the (positive terminal voltage is higher than the negative terminal, the output is 1, otherwise 0).
2. Any IO port output and SCM (based on process definitions) 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.
