This Ultrasonic Distance Sensor is an efficient submersible sensor to measure distance. Interfacing with it is the same as another cheap ultrasonic sensor, but it offers better performance and is compatible with harsher environments and is waterproof too! It can be easily interfaced with Arduino and Sample codes and projects are available.
There are many ultrasonic distance sensors in the market, but sometimes, this kind of sensor needs to work in vulnerable conditions. This Waterproof Ultrasonic Obstacle Sensor meets this requirement. It has a good performance and almost the same usage of an HC-SR04 module.
It is very easy to use, a control port with a 10US above high level can wait for high-level output at the receiving port. An output can drive the timer when this port is low can read the timer value, this time for the location of the time can be distance measurement.
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
- Upon detecting the signal, a high-level signal is outputted 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
Pin-Out details:
- +5V(positive)
- Trig(control)
- Echo(receive)
- GND(negative)
Applications:
- Horizontal distance
- Obstacle avoidance, automatic control
- Traffic control
- Security, industrial control
- Artificial intelligence, and research.
