DESCRIPTION:
This Waterproof Ultrasonic Distance Sensor is an industrial grade sensor to measure distance. Interfacing with it is same as other cheap ultrasonic sensors, but it offers better performance and can be used in harsher environments and is waterproof too! It can be easily interfaced with Arduino.
Product Features:
Small size, easy to use.
Low voltage, low power consumption.
High accuracy
Strong anti-jamming
Integrated with wire enclosed waterproof probe, suitable for wet, harsh measurement occasions.
Specifications:
Operating voltage: DC 5V
Quiescent current: 5mA
Total current draw: 30mA
Frequency: 40khz
Range: 25cm to 450cm
Resolution: about 0.5cm
Beam Angle: less than 50 degrees
Working temperature: -10 ~ 70 Celsius
Storage temperature: -20 ~ 80 Celsius
Application:
Horizontal distance
Obstacle avoidance, automatic control
Traffic control
Security, industrial control
Artificial intelligence, and research
The basic working principle:
Turn on TRIG Pin to 5V for at least 10us
The module will then automatically send 8 40KHz tones and automatically detect when the signal return after reflecting back from the object
On detecting the signal, a high level signal is outputed through the IO Pin ECHO. By keeping track of the time duration between transmitting and receiving the signal, the distance can be calculated. Distance = (Time to Receive Reflected Signal * speed of sound (340M/S)) /2
