Description
The JSN-SR04T is a waterproof ultrasonic distance measuring sensor, perfect for outdoor applications where you need to measure distances or detect objects in various weather conditions. Based on ultrasonic technology, this sensor emits sound waves and measures the time it takes for the echo to return from an object, calculating the distance to the object.
With its waterproof feature, the JSN-SR04T is ideal for projects that will be exposed to moisture, such as outdoor robotics, weather stations, and marine applications.
Key Features:
-
Waterproof: Designed for outdoor use, the JSN-SR04T is fully waterproof and can operate in rainy or wet environments, making it ideal for outdoor robotics or automated systems exposed to the elements.
-
Ultrasonic Technology: The sensor emits an ultrasonic sound wave and measures the time it takes for the sound to bounce back from an object, allowing it to calculate the distance accurately.
-
High Accuracy: Offers accuracy in measuring distances, typically in the range of 2cm to 400cm.
-
Wide Measurement Range: The sensor can measure from 2cm to 400cm with a typical accuracy of around 3mm, which is ideal for many robotics, automation, and distance sensing projects.
-
Low Power Consumption: Like most ultrasonic sensors, it consumes very little power, making it suitable for battery-powered systems.
-
Easy Interface: The sensor can easily interface with microcontrollers such as Arduino, Raspberry Pi, and other development boards using a simple digital input/output (IO) pin.
-
IP Rating: With its IP65 rating, it can handle dust, dirt, and water splashes, protecting it from environmental damage.
Specifications:
-
Power Supply: 5V (ideal for use with most microcontrollers like Arduino).
-
Operating Current: Typically 15mA, with a peak of up to 50mA during the transmission pulse.
-
Measuring Range: 2cm to 400cm (0.8 inches to 13 feet).
-
Accuracy: Typically 3mm.
-
Output: Echo and Trig pins for communication (distance data is read using the pulse-width of the Echo pin).
-
Frequency: Typically operates at 40kHz for ultrasonic waves.
-
Dimensions: Typically 45mm x 28mm x 14mm.
-
Waterproof Rating: IP65.
-
Operating Temperature: -20°C to +70°C.
How It Works:
-
Trigger: The sensor emits an ultrasonic pulse when triggered by a signal (via the Trig pin).
-
Echo: The ultrasonic wave bounces off an object and returns to the sensor. The sensor listens for the reflected signal and records the time it took for the sound to return.
-
Distance Calculation: Using the time it took for the pulse to travel to the object and back, the sensor calculates the distance based on the speed of sound.
-
Data Output: The distance is output through the Echo pin as a pulse width that is proportional to the measured distance, which can be processed by a microcontroller.
