Here is a tested Arduino project that uses 3 sensor probes as water level indicator with 3 leds and one LCD display + a simple controller that turns on a motor when the water has reached the desired ...

Water level sensors of the water tank at roof, and water level sensor of the water tank at basement (ground) can be connected to the circuit through sockets J1 and J2 respectively. Socket J4 is the DC ...

I now have it "working" using two types of sensors. I have a float sensor which just gives me a binary on/off. This works fine and would probably do what I need. Bonus for it being made for wet ...

I've got an Arduino/Bluetooth (Bluetooth Bee-Standalone). I've hooked it up with an HC-SR04, it's intended to be mounted at the top of a rain barrel to measure the water depth. What's the best ...

Water Level Sensors, Alexa In A Fish, And Modular Synths During World Create Day. ... The first is an LED matrix that eleven-year-old Daniyal brought to life using Arduino.

A low-cost (~$100), do-it-yourself (DIY) ultrasonic water level sensor/datalogger has been designed, constructed, and tested for use in education, citizen/community science, and research settings. The ...
