IoT Board with ultrasonic sensor

Looking for an IoT BOARD which would be able to measure the water level using ultrasonic sensor. The board needs to run on battery and should have cellular capability . Both the board and ultrasonic sensor needs to have an IP67 enclosure and should be compatible for an outdoor environment. The ultrasonic sensor needs to be able to measure atleast 10 feet of water. The hardware would be measuring the water level once a day. We would like to do a quick prototyping and then if successful we would scale this out to 150 locations. I would also like to know whether this board could be used to scale it out in production?

Hi @kiwi, I’m not sure about single product that could satisfy your requirements currently available or not, but seeedStudio have wide variety of modules available to make your product, and also you can contact seeed customization service.
