Waterproof Ultrasonic Module JSN-SR04T Distance Transducer Sensor for Arduino

Waterproof Ultrasonic Obstacle Distance Sensor Module is very similar to the ultrasonic sensors which are found in cars. This Waterproof Ultrasonic Obstacle Sensor shows some important constructional advantages over the conventional sensors. It comes in two separate parts one being the transducer which is the sensing element and the other being the control board.

There are many low cost ultrasonic sensor available in India. The problem with those sensors are that they are not suitable in industrial environment where there is lot of dust and can also be damaged due to water. This is where JSN-SR04T ultrasonic distance sensor comes into picture. This sensor is not for just using in the LAB for your project it is perfect for practical applications in commercial as well as Industrial projects.

Waterproof Ultrasonic Distance Sensor Module JSN-SR04T is an industrial grade sensor to measure distance. Interfacing with it is same as other cheap ultrasonic sensor, but it offers better performance and can be used in harsher environments and is waterproof too! It can be easily interfaced with Arduino and Sample codes and projects are available.

The sensor comes with a 2.5 m long cable that connects to a breakout board which controls the sensor and does all the processing of the signal. Note that only the sensor and the cable itself are waterproof, if you get water onto the breakout board, the sensor might stop working. The module is capable of providing information of the objects between the distance range of 250 mm to 4500 mm.

An ultrasonic distance sensor works by sending out ultrasound waves. These ultrasound waves get reflected back by an object and the ultrasonic sensor detects them. By timing how much time passed between sending and receiving the sound waves, you can calculate the distance between the sensor and an object. The main specialty of this sensor, besides it being waterproof, is that this sensor uses only one ultrasonic transducer. This transducer serves as both the transmitter and the receiver of the ultrasound waves.

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:

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 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 :

• +5V(positive)
• Trig(control)
• Echo(receive)
• GND(negative)

Application:

• Horizontal distance
• Obstacle avoidance, automatic control
• Traffic control
• Security, industrial control
• Artificial intelligence, and research

Package Includes :

1 x Waterproof Ultrasonic Module JSN-SR04T Distance Transducer Sensor for Arduino
