A HIGH on nOE causes the outputs to assume a high impedanceOFF-state
Current : 43A
This module use is very easy which you could direct control by push button on board or by Microcontroller such as Arduino
Cable length: 40cm
It also has better resistance to vibration and mechanical shock and better moisture-proof performance
Ultrasonic Sensor ( Distance Measuring Module ) Encoder A HIGH on nOE causesIntroduction: HC SR04 ultrasonic module can offer non contact distance sensing function, the range from 2cm to 400cm. and the range accuracy is up to 3mm; the module includes ultrasonic transmitter, receiver and control circuit. The sensor measures distance using sonar; an ultrasonic (well above human hearing) pulse is transmitted from the unit and distance to target is determined by measuring the time required for the echo return. The module is based
