Arduino - Pressure sensor for water level

$250-750 USD

Paid on delivery
I have been working on a project, where It would be nice to measure the depth of water, from 10 cm depth to around 10 meters at max. With a resolution of +- 1-2 cm. I am currently using a development kit from Arduino and a pressure sensor. And in the future i think it will be beneficial to measure salt in the water, to know the density of it and by that be able to calculate the actual Depth (height) of the water. Do you think you can help me with this project? If you do, leave a message, where you describe how you think you will be doing it and a realistic bid.

How i'm thinking to implement what you are asking: 1. We will start for the formula of fluid pressure: P = r * g * h; 2. We will find out h using above formula: h = P / (r * g) Relevant Skills and Experience I've create a wireless sensor network using Arduino. I have used sensors to measure temperature and humidity.

Hi, I think can help you with measuring water level and we can figure out some sensor for salt measurement too. Once the sensors are decided, I can easily code for them using Arduino.

I can make a system to calculate the depth and density of the water using pressure sensor only. for density we can calibrate the pressure for a known depth. & use this for depth calculation Relevant Skills and Experience I am an electronics and communication engineer with 4+ year experience in this area. I have used similar system in my Under water robotic project. Proposed Milestones $244 USD - Initial coding and designing $150 USD - Testing $50 USD - final step what type of sensor you are going to use ? the accuracy of the system will depend on the sensor.

Hello, I can certainly help you out with the project. The only uncertainty is the equipment. Either you would send it to me or I can order it myself if it has a resonable price. I am a senior software developer and I love this kind of projects. I have over 5 years of experience in C/C++.

I would use an ultrasonic sensor for the height measurement and a conductivity sensor for the salt content. There are a few different types of ultrasonic sensors available ranging in price.
