2pcs HC-SR04 Ultrasonic Module Distance Measuring Transducer Sensor for Arduino Robot 5V

Notice:

• This module is not suitable to connect with electric power, if you need to connect this module with electronic power, then let the GND terminal of this module to be connected first, otherwise, it will affect the normal work of the module.

Description:

• This module performance is stable, measure the distance accurately. performance nearly the same as SRF05, SRF02 SRF05, SRF02 ultrasonic distance measuring module and other comparable. Module High precision, blind spots (2cm) super close.

• Voltage: DC 5V
• Static current: less than 2mA
• Electrical level output: 5V high
• Electrical level output: 0V low
• Induction angle: less than 15 degrees
• Detection distance: 2cm-450cm
• High precision: 3mm
• Wiring: VCC, trig (controlling), echo (receiving), GND
• Doc: Pls contact me for Doc if needed.

• VCC
• trig(T)
• echo(R)
• GND

• using IO trigger distance, the high signal to at least 10us
• module automatically sends eight 40khz square wave, automatically detects whether a signal return;
• 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;
