SunFounder 2 pcs Ultrasonic Module HC-SR04 Distance Sensor for Arduino UNO MEGA R3 Mega2560 Duemilanove Nano Robot Rapsberry Pi 3, 2 & RPi Model B+ XBee ZigBee
[Product Information]
- Increased ranging distance to 7m, providing stable signal within 5m, and gradually faded signal outside 5m till disappearing at 7m position.
- Uses IO trigger for ranging, generating high level signal of at least 10us.
- Operating voltage: 5V; Working current: 16mA.
- Equipped with anti-reverse pin socket – making the wiring much tighter and convenient; 4-pin anti-reverse cable also included.
- Uses the MCU STC15W104 which has a built-in clock, no need of external crystal oscillator.
