Highlights:

This module can count and measure the frequency of the pulse signal, display the number of counts or the frequency of the signal through the digital tube, output through the serial port, and read the count value or frequency value directly from the computer by the AT command.
 
At the same time, the module can set counting threshold or frequency threshold to control the relay switch so as to realize intelligent control of electrical appliances.
 
 
 
 
Parameters:
 
*Working mode: counter (COUNT)/frequency detector (FRE)
 
*Output mode: (1 serial port output 2 state level output 0 or 3.3V)
 
*Indicator light:
 
1. Power Indicator Lamp
 
2. State Alarm Indicator (Lighting: Relay Work)
 
*Instruction mode: AT instruction
 
*Counting range: 0-999999999
 
*Frequency measurement range: 0.01-700000Hz

*Display mode:
 
1. Digital tube display
 
2. Transfer from USB to TTL and display by computer serial assistant software
 
 
 
Input pulse acquisition mode:
 
FALL (descending edge) / RISE (rising edge) - that is, the object counts when it passes through or leaves the photoelectric switch. In contrast to PNP and NPN, one counts by time and the other counts when it leaves. Customers can set capture mode according to their own needs.
