The Pi then triggers the relay module that controls the water pump for only five seconds ... PIR motion sensor, LED, and Arduino. The Arduino monitors the motion sensor and controls the LED ...

3 shows the circuit diagram of the automatic water level indicator cum controller. It is built around an Arduino Uno board (MOD1), three LEDs, a 5V SPDT relay, and other components. First, all sensors ...

board compatible with Arduino, along with a range of sensors such as IR, sound, gas, soil moisture, and more. It also includes various components like a 1-channel relay board, resistors, LEDs, a ...

We use the Arduino board as a slave board for collecting data from the sensors and for controlling the relay which turn on/off the water pump. We used Node-RED to create a dashboard interface, where ...

Sure, you can save money by using less hot water, but an even smarter move is upgrading to a more efficient way of heating it. Enter the heat pump water heater. Instead of generating heat directly ...

For instance, drinking water with a pH above 9 might pose risks for people taking drugs that block stomach-acid production, such as proton pump inhibitors, because it can further raise the stomach ...

Bill Sullivan receives funding from the National Institutes of Health. Water that comes straight from natural sources, dubbed “raw water,” is gaining popularity. Raw water advocates reject ...

Feb. 19, 2025 — Nitrogen is essential for all life on Earth. In the global oceans, however, this element is scarce, and nitrogen availability is therefore critical for the growth of marine life ...
