waterproof lcd arduino manufacturers

Are you trying to read liquid? temperature and don’t know how?? Here is one of the ways on how to get the liquid temperature using DS1820B waterproof temperature sensor on Maker UNO.. And the reading will be displayed on the I2C LCD. It’s so easy!

The JSN-SR04T is an easy to use waterproof ultrasonic distance sensor with a range of 25 to 450 cm. If you are planning to build a water level measuring system or if you need to take other distance measurements outside, then this is the sensor you need!

The sensor comes with a 2.5 m long cable that connects to a breakout board which controls the sensor and does all the processing of the signal. Note that only the sensor and the cable itself are waterproof, if you get water onto the breakout board, the sensor might stop working.

So what are the differences between this sensor and the HC-SR04? The main difference, besides it being waterproof, is that this sensor uses only one ultrasonic transducer instead of two. This transducer serves as both the transmitter and the receiver of the ultrasound waves.
