Ultrasonic Sensor Module Distance Measuring Sensor for Arduino

Ultrasonic Sensor Module Distance Measuring Sensor for Arduino

Main technical parameters:

• Voltage: DC 5V
• Static current: less than 2mA
• Electrical level output: 5V high
• Electrical level output: at the end of 0V
• Induction angle: not more than 15 degrees
• Detection distance: 2cm-450cm
• High precision: 2mm

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

3 Module works:

(1) Using IO trigger distance, the high signal to at least 10us;

(2) Module automatically sends eight 40khz square wave, automatically detects whether a signal return;

(3) A signal back, through the IO output a high electrical level, high electrical level duration is: the ultrasound time from launch to return. Test distance = (time of the high electrical level * speed of sound (340M / S)) / 2;
