Ultrasonic sensor module US-100 

The ultrasonic sensor module us-100  is a convenient way for measuring distances from objects. This module has a lot of applications such as parking sensors, obstacle and terrain monitoring systems, industrial distance measurements, etc. It has a stable performance and high accuracy ranging from 2cm to 450cm. The module sends an ultrasonic signal, eight pulses of 40kHz square wave from the transmitter; the echo is then picked up by the receiver and outputs a waveform with a time period proportional to the distance. The connected microcontroller accepts the signal and performs necessary processing.

Specifications:

• Input voltage: 5V DC
• Quiescent current: less than 2mA
• Level output: 5V high
• Level output: at the end of 0V
• Induction angle: not more than 15 degrees
• Detection distance: 2cm-450cm
• Precision: up to 1mm
• Dimensions: 4.4cm x 2.6cm x 1.4cm
• Weight: 43g
