Ultrasonic Distance Module,
Description: Ultrasonic sensors work by emitting sound waves at a frequency too high for humans to hear. They then wait for the sound to be reflected back, calculating distance based on the time required. This is similar to how radar measures the time it takes a radio wave to return after hitting an object.Ultrasound is a relatively high-frequency sound with strong directivity. The principle of ultrasonic ranging is to use the propagation velocity of ultrasonic waves in the air as known and to measure the time when the sound waves encounter an obstacle after they are emitted. According to the transmitting and receiving of the time difference to calculate the actual distance from the launch point to the obstacle. Thus, the ultrasonic ranging principle and radar principle are the same.IOE-SR05 Ultrasonic Ranging Module Features:1. Small size, PCB board size is only 2.2 * 3.6CM, suitable for demanding occasions.2. At least only one IO data port can accept the measurement of distance hexadecimal data, with data output enables the terminal; you can control or directly through the IO port ground handling.3. Measuring the distance of only 18ms, greatly reducing the measurement time, especially for robot control is particularly suitable.4. Reached the theoretical no blind zone, basically no blind zone test range.5. AAAA automatically returns over-range data to reduce the wait time after over-range;6. A red LED indicates as soon as the module detects obstacles.
