Water Flow Monitor with ESP32 and MQTT This project monitors water flow using an ESP32 and a YF-S201 sensor. It calculates real-time water usage and publishes the data to an MQTT broker. An LED is ...

Note: This diagram shows the signal flow for one sensor. The Tank High Level and Tank Low Level sensors are connected identically using separate channels on the logic level shifter (e.g., HV2/LV2 and ...

But like I said, it's a cool project. I've thought about building an ultrasonic water level sensor, connected to an ESP32 or Pi Zero to report water levels to... something TBD.

This article presents a novel vision-based artificial lateral line (ALL) sensor, FlowSight, enhancing the perception capabilities of underwater robots. Through an autonomous vision system, FlowSight ...
