Ultrasonic Sensor ( Distance Measuring Module ) Breakout It can measure a wide

It can measure a wide range of temperature from -55°C to +125° with a decent accuracy of ±5°C

0 Interface ( 3 foot patch )

Rotary Encoder Module is an incremental encoder which means that it outputs a pulse each time that the shaft is rotated one detent (click)

This enables the use of current limiting resistors to interface inputs to voltages in excess of VCC

Ultrasonic Sensor ( Distance Measuring Module ) Breakout It can measure a wideIntroduction: 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
