Description
JSN-SR0T4 is a waterproof ultrasonic distance measurement sensor module with a range of 25cm-450cm non-contact distance measurement. It is very similar to the ultrasonic sensors which are found in car bumpers. JSN SR-04 Sensor’s working is same as HC-SR04. But JSN SR-04 sensor has only one transducer that is connected through a 2.5 Meter cable. This sensor module comes in two separate parts; one being the transducer, which is the sensing element, and the other being the control board. The sensor works with the simple high school formula -
Distance = Speed X Time
The Ultrasonic transmitter transmits an ultrasonic wave. This wave travels in air and when it gets objected by any material, it gets reflected back toward the sensor, this reflected wave is observed by the Ultrasonic receiver module. Now, to calculate the distance using the above formulae, we should know the Speed and time. Since we are using the Ultrasonic wave, we know the universal speed of US wave at room conditions which is 330m/s. The circuitry inbuilt on the module will calculate the time taken for the US wave to come back and turns on the echo pin high for that same particular amount of time.
