vibration sensor
RelaysParameters:*Main Chips: Operational Amplifier Transformer Single Chip Microcomputer*Operating Voltage: 5V (Serial Port Provided)*Work mode: Connect serial port (read value directly by serial assistant)*Detection current range: AC0-10/20Characteristic:1 The output signal is analog voltage (0-5V)2. Output to serial port transfer from USB to TTL module and connect with computer directly to pick up reading which is more convenient.3. On-board potentiometer adjustable threshold control relay compared with analog voltage4. It is more convenient to set threshold and control relay by serial port.5. With installation holes it is convenient for firmware installation and use.Application:AC current equipment such as motor over-current detection stop-up protection short circuit protection detection over-current protection demonstration teaching experiment and other occasions are convenient for secondary development; suitable for different loads including inductive load capacitive load resistance load detection.
