Product Details

Specifications

Stable performance, precise measure of distance

Stable performance, precise measure of distance. And can compare with SRF05, SRF02 Ultrasonic Ranging Module. Module precision,blind spots (2cm) super close, stable distance measurement!

Feature:

Voltage: DC5V

Quiescent current: less than 2mA

Level output: 5V high

Level of output: 0V low

Induction Angle: not more than 15 degrees

Detection distance: 2cm-450cm

High precision: better than 2mm

Wiring, VCC, trig 's (control side), echo (receiving end), GND

Note:

(1) IO trigger ranging to at least 10us high signal;
(2) module automatically sends eight 40kHz square wave, automatically detect whether a signal return;
(3) a signal to return to a high IO output, high duration of the ultrasonic time from launch to return. Test distance = (time high * speed of sound (340M / S)) / 2
