”US-015 Ultrasonic Ranging Module

1 Overview
The US-015 ultrasonic ranging module can realize the non-contact ranging function of 2cm~4m, the power supply voltage is 5V, the working current is 2.2mA, and it supports GPIO communication mode, which is stable and reliable.

US-015 Ultrasonic Ranging Module
Working voltage: DC 5V
Working current: 2.2mA
Working temperature: 0~+70 degrees
Output mode: GPIO
Sensing angle: less than 15 degrees
Detection distance: 2cm-400cm
Detection accuracy: 0.3cm+1%

Measurement cycle: After receiving the high-level pulse output by the US-015 through the Echo pin, the next measurement can be performed, so the measurement cycle depends on the measurement distance. When the US-015 is very close to the measured object, the Echo returns The pulse width is narrow and the measurement period is short; when the US-015 is far away from the measured object, the pulse width returned by the Echo is wider, and the measurement period is correspondingly longer.

In the worst case, the measured object exceeds the measurement range of US-015, and the pulse width returned at this time is the longest, about 80ms, so the measurement period in the worst case is slightly larger than 80ms (85ms is enough).”
