0.96" Inch I2c IIC Serial 128x64 Oled LCD LED White Display Module for Arduino 51 Msp420 Stim32 SCRBrand: 0.96" Inch I2c IIC Serial 128x64 Oled LCD LED White Display Module for Arduino 51 Msp420 Stim32 SCR

One thing i noticed is that while i use the vktech ds18b20 waterproof temperature sensors, in the tutorial i found here (http://www.adrirobot.it/sensori/DS18B20/sensore_ds18b20_Arduino.htm) there is a picture of the IC ds18b20. Is this IC located in the vtech sensor that appear in the picture? https://www.amazon.com/Vktech-DS18b20-Waterproof-Temperature-Transmitter/dp/B00CHEZ250

The boxes are in and I used the one sized 120 x 70 x 20 mm. Cut out a frame as spect on the Nextion site (https://nextion.tech/datasheets/nx4832k035/) as 73.44 mm(L)×48.96 mm(W). Glued 4 nylon bolts into the lid to hold the Nextion PCB which I screwed down with nylon nuts. Open cell rubber is used to waterproof the screen fitting and as a seal between the lid and the box. Drilled a 6 mm hole in the back to lead the wires through. The idea is to mount the Arduino Nano in the center at the back so it fits the circular opening already available in the console from the old display.

However, using the HC-SR04 outside is a different story. It is a pretty fragile device and can easily be damaged by dirt, or even high winds. And, above all, it is not waterproof.  Even sealing up its circuit board would not protect it, as the two transducers it uses are essentially just small speaker/microphones.

The A02YYUW is an ultrasonic distance sensor that bears some resemblance to the HC-SR04 in that it has a separate receiver and transmitter.  The device is enclosed in a rubber-like material and is fully waterproof.

If you need an ultrasonic distance sensor that is waterproof, then either of these units would make an excellent choice.  They both performed well, and they are rated for harsh environments.

They are, however, more expensive than the HC-SR04, so if you don’t require a rugged waterproof sensor then the latter is still a more economical choice.

Learn to use the JSN-SR04T and A02YYUW waterproof ultrasonic distance sensors with an Arduino. In this article, you"ll learn how these sensors work, how they compare to one another, and how to use them with an Arduino.
