Product Description
This text describes an ultrasonic sensor that has some advantages over conventional ones. It consists of two parts: a transducer, which is the sensing element, and a control board. The text can be rewritten as follows:
If you need an ultrasonic sensor that can measure distance in harsh or wet environments, you might want to consider this Waterproof Ultrasonic Obstacle Sensor. Unlike other sensors, it has a separate transducer that can be placed away from the control circuitry. This makes it more durable and versatile. It can detect objects between 250 mm and 4500 mm away, and it is easy to interface with Arduino. You can find sample codes and projects online. This sensor is similar to the ones used in cars, but it has a better performance and a higher resistance to water and dust.
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.
- 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
Wiring of Waterproof Ultrasonic Obstacle Sensor Module with Probe JSN-SR04T: –
- +5V(positive)
- Trig(control)
- Echo(receive)
- GND (negative)
Applications of Waterproof Ultrasonic Obstacle Sensor Module with Probe JSN-SR04T:
- Horizontal distance
- Obstacle avoidance, automatic control
- Traffic control
- Security, industrial control
- Artificial intelligence, and research.
Pin Description of JSN SR-04T
S. NO. | Pin Name | Pin Description |
1 | 5V | Positive supply pin of the sensor |
2 | Trig | Input pin of sensor. This pin has to be kept high for 10us to initialize measurement by sending ultrasonic waves. |
3 | Echo | Output pin sensor. This pin goes high for a period that will be equal to the time taken for the ultrasonic wave to return to the sensor. |
4 | GND | This pin is connected to the Ground of the system. |
