Hi

I'm looking how to construate the instrument discribed follow:
I want to measure water level only during windless periods. Therefore I need that the sensor starts laser distance meter only then and tracking the water level every 1 min until wind strats to bolwing again. The laser readings must save to SD and send to server also. The laser must be waterproof and can work year-round. Working temperature +50...-30 C. The size of laser and sensor, also timer and battery could not be larger than 10x10x10 cm.

Could you suggest where from I could get such instrument or how to constructed it. Maybe you can give detail list about concrate details I need for it. I mean what kind of sensor component and laser components I need. I know that e.g Disto A6 i good for distance tracking but does anyone know how to connect it with server and sensor? Anyway, I need sth like Disto A6 but with other properties described before.
