Waterproof Ultrasonic distance sensor JSN-SR04T 20-450cm

Index: MOD-07266 EAN: 5904422310066

Waterproof ultrasonic sensor operating in the range from 20 cm to 450 cm. It is powered with voltage of 5 V. The output is a signal whose duration is proportional to the measured distance. The sensor is compatible with popular sensor HC-SR04, which means that the sample programs and libraries will work correctly for both sensors.

Description

Waterproof ultrasonic sensor operating in the range from 20 cm to 450 cm. It is powered with voltage of 5 V. The output is a signal whose duration is proportional to the measured distance. The sensor is compatible with popular sensor HC-SR04, which means that the sample programs and libraries will work correctly for both sensors.

We encourage youto see the user's guide which includes a sample programfor handling ultrasonic sensors with Arduino.

The sensor has four leads that are compatible with themodule HC-SR04:VCC- supply voltage 5 V,GND- mass of system and the signal pins - EchoandTrig.

Method of application

To begin the measurement, you must indicate on the TRIG pin, pulse voltage (high state of 5 V) for 10 us. The module measures distances using sound wave with a frequency of 40 kHz. To microcontroller, a signal is sent, in which distance depends on the duration of high state, and it can be calculated by the formula:
 

test distance = (high level time × velocity of sound (340m/s) / 2

where:

  • test distance - the measured distance 
  • high level time - duration of high state
  • velocity of sound - velocity of projecting the sound waves in air - 340 m/s

 

In short, to get the result in cm, use the formula:

distance[cm]= ( high level time[us]* 34 ) / 1000 / 2

It works well, but you have to remember to wait half a second before taking another measurement so that the sound signal from the previous measurement does not reach the sensor, otherwise the data may be unreliable. Placing the probe socket on the back of the board can be problematic, as it effectively prevents easy attachment of the sensor to the structure. I wonder if the probe will actually prove to be waterproof, and if so, for how long.

I recommend it super

I got this kit up and running in minutes on ESPHome and so far it works great. I just don't understand why the angular sensor is included. I used it to measure the liquid level in the tank, and because the sensor is at an angle, I had to combine it with an additional housing at an angle to compensate for its inclination. In my opinion, a simple sensor would be better or some option to choose in the form of two independent sets.

ok.

Works and gives the correct distance. For domestic but also fully professional use. I recommend.
