HC-SR04 Ultrasonic Module Distance Measuring Transducer Sensor For Arduino

Features:

• Working Voltage : 5V(DC)
• 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: Up to 0.3cm
• trigger (control side) signal: 10us TTL impulse
• Echo (receiving side) signal : TTL PWL signal
• Wiring:
• VCC
• trig
• echo
• GND
• Test reference:
• (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;

Package Includes:

• 1 x HC-SR04 Ultrasonic Module Distance Measuring Transducer Sensor For Arduino
