HC SR04 Ultrasonic Sensor Module or Bracket Holder Yellow/Blue

ULTRASONIC SENSOR HC SR04

- Voltage : 5VDC, 15mA, 40Hz, 2cm to 255cm,
- Measuring Angle : 15degree, 45*20*15mm
- Send IO trigger pin with at least 10us active high signal.
- The module will send automatically eight 40kHz pulse from the transmitter(that’s why it is called ultrasonic). Any object detected will reflect the transmitted pulse back to the receiver.
- The signal return in active high level can be detected at pin ECHO. The high level time, which is time of high output duration from sending ultrasonic and returning, resembles the distance.
- Test distance = (high level time×velocity of sound (340M/S) / 2,
- Avoid soft objects as it will absorb most of the transmitted waves
