This performance of the ultrasonic sensor distance measuring module is stable, measure the distance accurately. The module is with High precision, blind spots (3cm) super close. This module provides a full set of ranging process. FeaturesWorking voltage : 5V(DC)Static current: Less than 2mA.Output signal: Electric frequency signal, high level 5V, low level 0V.Sensor angle: Not more than 15 degrees.Detection distance: 2cm~450cm.High precision: Up to 3mmMode of connection: VCC / trig(T) / echo(R) / GND WorkingProvide the IO trigger supplying at least 10us sequence of high level signalThe module automatically sends eight 40khz square wave and automatically detects whether receive the returning pulse signalIf there is a return signal, the output level will be high and the high time of the signal is the time from transmitting to receiving. Please refer the datasheet for exact details.
