Hi all, total noob here but i need to develop my understanding of creating a river level monitor. I have settled on the idea based around the ultrasonic sensor HC-SR04 and have a section of code to upload which appears to be working. what i am missing is a way of getting the device to work and take readings autonomously and translating that reading into visual graphics. bit of background for you all to start with i live in a village that was flooded heavily on boxingday (we even made the front cover of the tabloids) but we have a relatively speaking small amount of monitors on our river and tributaries. i want to empower the local community with plans and demos on how to build their own river level monitor and we can then look at an opensource project where everyone's monitor uploads via their wifi. As we implement flood alleviation schemes the community can see in rel time how this helps them avoid being flooded.
Any help would be appreciated .
