JSN-SR04T Waterproof Ultrasonic Obstacle Distance Sensor Module

The Waterproof Ultrasonic Distance Sensor Module JSN-SR04T is an industrial-grade sensor designed for measuring distance in harsh environments. Here are its features, specifications, and applications:

  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: 5V
• Operating Current: 30 mA
• Static Current: 5 mA
• Operating Range: 25cm to 4.5m
• Resolution: 0.5 cm
• Detecting Angle: < 70°
• Operating Temperature: -10°C to +70°C
• Cable Length: 2.5 meters
• Dimensions (LxWxH): 41 x 28 x 12.5 mm
• Weight: 50 gm

  Working Principle:  

1. Turn on TRIG Pin to 5V for at least 10uS.
2. The module will automatically send 8 40KHz tones and detect when the signal returns after reflecting from the object.
3. 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 using the formula: Distance = (Time to Receive Reflected Signal * speed of sound (340M/S)) / 2.

  Wiring:  

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

  Applications:  

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

  Package Includes:  

• 1 x Waterproof Ultrasonic Obstacle Sensor with 2.5m Separate Probe

This sensor offers improved performance and reliability in comparison to standard ultrasonic sensors, making it suitable for industrial and commercial projects.
