Universal DC12V 15mA Car Off-Road Ulsonic Alarm r Motion Tool

1, the scope of applicationApplicable to the supply voltage of DC: 9-12V, the maximum operating current of the host is le than or equal to 15mA2, product overviewThis product detects moving obstacles in front by sending and receiving ulsonic change signals, and triers the switch signal to start when an object moves or approaches the set distance within the front range. It can control the external circuit to perform sound and light alarm, or the purpose of switch control. ;3, the main technical s4, DescriptionWhen the working voltage is connected, the red (nsmitting,) blue (receiving) LED lights f alternately, indicating that the ulsonic nsmiion and reception are normal, and then the green LED indicator in the middle will f to indicate that the system has entered the normal working state, and the green light will be off in the non-sensing state.Fix the dispment device and adjust the distance adjuster to reach the required control distance range.
