Key Features of the US-100 Ultrasonic Sensor:

Ultrasonic Distance Measurement: The US-100 sensor uses ultrasonic pulses to measure the distance to an object. It emits ultrasonic waves and measures the time it takes for the waves to bounce back after hitting an object.

Temperature Compensation: This sensor includes temperature compensation, which means it can adjust its measurements based on the ambient temperature. Temperature can affect the speed of sound, and the sensor compensates for this to provide accurate distance readings.

Distance Range: The US-100 sensor typically has a range of about 2 centimeters (cm) to 400 cm, although the actual range may vary depending on the specific model and environmental conditions.

Output: It provides distance measurements in either centimeters (cm) or inches (in) through its digital output pins. Some versions of the sensor also provide temperature readings in degrees Celsius (°C) or Fahrenheit (°F).

Voltage Compatibility: The sensor is often compatible with both 3.3V and 5V power supplies, making it suitable for various microcontroller and embedded systems.

Operating Principle: The US-100 emits ultrasonic pulses from its transmitter and waits for them to bounce back from an object. By measuring the time it takes for the pulses to return, it calculates the distance to the object.
