WCS2702 current detection sensor high precision AC/DC current detection 2A current limiting protection relay serial port -79464

1.Description:
It is a current detection sensor module.In the test process,if you need to switch from DC test to AC test,or switch from AC test to DC test,you only need to calibrate and retest.It can be used for motor over-current detection,short-circuit protection detection,over-current protection,demonstration teaching experiments,different load detection and so on.

2.Feature:
1>.UART directly read the dual axis horizontal value
2>.The on-board potentiometer can adjust the threshold and control the relay in comparison with the analog voltage.
3>.It can set alarm value
4>.Adapt to MCU and PC
5>.Support AC and DC current test
