Ultrasonic sensor

This is the US-100 Ultrasonic Sensor Distance Measuring Module with Temperature Compensation. The US-100 Ultrasonic Sensor can measure or detect the object in the range of 2 cm to 450 cm distance.
This US-100 has 2.4V to 4.5V wide voltage input range, the static function GPIO, a serial variety of communication methods, within the band watchdog, stable and reliable.
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.
