work performance. Review by Allen
I purchase 2 of these, one is used to test the vibration of th washing machine, and the other one is used to make a autoalarm. And them work perfectly for this task as expected! this module is easy to connect and use, what's more,it can respond in time. when using you must pay attention to that power supply can not meet the polarity, otherwise likely to burn out the chip.
