      I want to make a water depth sensor .
      I have seen some YouTube videos of water proof ultrasonic sensor ,but it's will not work under water.
      Please any one tell me which sensor should I use.
      I want to sense it he depth of water.
      From surface to the bottom .
      The sensor should be on the surface of water

        @Geethesh Glad that you are active with makergram. To help with your query please let me clarify whether you want to know the level of the water surface or know how much depth a certain water body is at??

              Hi @Geethesh ,

              I got a few sensors to measure the depth of water, some of them are listed .

              • MS5540C , example link
              • Bar30 High-Resolution 300m Depth/Pressure Sensor
              • Miniature Barometer Module * OTT ecoLog 1000 Water Level Logger

                @Geethesh Try using Sharp IR sensor.....it's more effective than normal IR and can measure distances accurately using ir Rays. Try using it.

                    @rafitc99 I changed the buffer and that solved the problem. Thanks a lot for coming to my rescue.

                    @salmanfaris I did change the buffer size and everything is working perfectly. Thanks coming to my rescue.

                  • @codelery said in Help needed: Arduino Wireless Notice Board project:

                    I am using the hardware serial (pin 0 and 1 on Arduino Uno)

                    As @rafitc99 mentioned, you need to expand the Serila buffer, in the hardware serial also the Arduino board package implements a 64-byte ring buffer for send and receive on the hardware serial messages. So you need to change that to 256 as per your message length.

                    @rafitc99 The thing is that I am not using the SoftwareSerial library in receiving the message from the first microcontroller. I am using the hardware serial (pin 0 and 1 on Arduino Uno)
