US-100 Ultrasonic Sensor Distance Measuring Module with Temperature Compensation

The US-100 Ultrasonic Distance Sensor Module operates from a wide voltage range and provides both digital and serial data output modes.

The US-100 features accurate temperature corrected range detection. It can output the distance in millimeters using a serial data output mode. Alternatively, the distance can be calculated by measuring the amount of time that a digital output is held high.

This sensor can be used with both 3.3V and 5V microcontrollers and only consumes 2mA when idle.
