Description
【What it does】: The ultrasonic sensor emits ultrasonic waves through the head and receives the waves reflected from the target, thereby measuring the time between transmission and reception to measure the distance to the target..【Features】: Ultrasound is a mechanical wave with a vibration frequency higher than 20kHz.It has the characteristics of high frequency, short wavelength, small diffraction phenomenon, good directionality, and can become a ray for directional propagation, etc..【Product advantages】: Under the same range, it has a smaller working current (3mA);Low power consumption (approx. 2 mA per measurement, max. 100 mA per second)..【Specification】: Operating Voltage: 3.3-5V,Quiescent current: less than 2mA;Effectual angle: less than 15°;Distance: 2cm~400cm;Resolution: 0.3 cm..【Applications】:The HC-SR04 is ideal for various projects that require distance measurement, such as obstacle avoidance.please go to the address:https://bit.ly/38RKuUv
