This sensor works on the principle of variable resistance. The sensor consists of a series of parallel exposed conductors. Together this series acts as a variable resistor, whose resistance varies ...

This is a very simple liquid detector that use a relay to open an evacuation van. You can use it for water or any liquid that conduct electricity. Use any PNP transistor that can stand the relay ...

Based on dual BMP280 pressure sensors and a KY-013, water, temperature sensor this project is intended for monitoring evaporative and decorative ponds, creeks or wells. The functionality could also ...

This project is a simple and efficient water level monitoring system designed using an Arduino Uno. It helps detect and indicate the water level in a tank or container, preventing overflow and dry-run ...

Some households have water supplies that contain higher than desired levels of minerals. This condition is called hard water. There is nothing harmful about hard water but it does leave mineral ...

Baumer has created a capacitance-based level detector for water-based liquids. “Capacitive sensing technology offers advantages, especially on applications involving aggressive liquids, food or ...

ABLIC’s battery-less water leak detection sensor extends the communication range by approximately two times that of its ...

The First Alert L1 is a battery-powered sensor that sends alerts to your phone when a sink or appliance springs a leak or when the temperature drops below a certain level. Damage caused by leaks and ...

When interfacing with the real world, there are all kinds of sensors available which will readily communicate with your microcontroller of choice. Moisture, pH, humidity, temperature, location, light, ...

We are currently in the process of putting in a backyard pool. This is an in-ground gunite pool. I inquired about an auto-fill system from the pool builder but he talked me out of it. He explained ...
