Using a Project Lab and a distance sensor, build this reference project that monitors liquid levels on a container such as a cooler, bucket, or even a black 60L barrel.
On your Project Lab, connect a distance sensor like a Time Of Flight distance sensor (for a Bench prototype) on the I2c qwicc connector, or a MaxBotix (for a Lab prototype), fixed on the lid of a water cooler or whatever container you're using, for example:
Looking at the TankLevelMonitor.Core, a few things worth mentioning:
ITankLevelHardwareis an interface that defines what your IoT Project is composed of, which in this case, is a Project Lab and a sensor of typeIRangeFinder, which are distance sensors.HardwareTypesis an enum where you can have multiple hardware configurations. In this case, there is aBenchPrototypeand aLabPrototype.TankLevelBenchPrototypeandTankLevelLabPrototypeareITankLevelHardwaredefinitions where the only diference in this example is the distance sensor type.
This project sample reads Temperature, Humidity and Pressure from Project Lab's BME688 atmospheric sensor onboard, and gets the container's Volume, sending it to Azure IoT Hub.
Azure Function project that is used receive incoming data from IoT Hub and updating a digital twin using Azure Digital Twins of the Tank Level Monitor.
Basic Getting Started app that shows the atmospheric and tank level readings on the Project Lab v3 display.
Store atmospheric and tank level readings on SQLite running on Meadow.
Speed up development build cycles by running Tank Level's UI screen straight from Windows using WinForms. Also learn how you can simulate a distance sensor by checking out the SimulatedDistanceSensor driver.
