433 MHz water quality sensors
« on: March 16, 2020, 03:52:29 PM »
I've been googling around to see if I can spot some 433 MHz sensors for PH, DOD and maybe other water quality parameters for sea water. I've found a couple of bluetooth units but I need 150 - 500 ft line-of-sight range. This thing looks like fun: https://www.alibaba.com/product-detail/PH-ORP-Conductivity-Dissolved-Oxygen-Concentration_60668924545.html?spm=a2700.7724857.normalList.41.17ca52e8eEpLeq and I've sent off a query about $$.

Any other ideas or pointers most welcome.

Look very similar to Libelium Sensors.
