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 ...

My water level maintenance consists of dropping a garden hose in the pool and letting it run for 30 minutes; I have to do this less than once a month. But like I said, it's a cool project.

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 ...

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.

This is a simple arduino project for a soil moisture sensor that will light up a LED at a certain moisture level. It uses Arduino Duemilanove microcontroller board. Two wires placed in the soil pot ...

It runs on an Arduino MEGA 2560 PRO (or similar microcontroller) and supports a wide array of additional hardware including pressure transducer, water level sensor, flow meter, OLED display, and more.

As the top sensor goes low (water above level C), the CLR signal is activated and the output of the flipflop is low. This allows Q1 to turn on and activate a triac or relay for the pump.

By analyzing those patterns, an onboard Raspberry Pi microcomputer is able to determine the current water level to within an accuracy of plus or minus ~1.5 cm (0.6 in). That data is transmitted to ...
