Control LED strip with Arduino Ultrasonic sensor Overview In this mini-project, we will be combining an ultrasonic distance sensor and an addressable LED strip. The goal is to trigger the LED strip ...

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 ...

Arduino-based water level detector with LED indicators and buzzer alerts. Uses a capacitive sensor for real-time monitoring of tanks/reservoirs. Compact, open-source design ideal for STEM/DIY proje ...

Born from the experience of the Kerala flood, TK explores how to make a simple water quality meter with a turbidity sensor. This simple project shows the theory and basic components to build a ...

In this article, we present a pH meter that can accurately measure the pH value of a solution. We use a dedicated sensor, the Arduino UNO R4 Minima board.

When the sensor detects that the moisture content is already below 30%, it sends a signal to the Arduino, which, in turn, activates a water pump to provide hydration to the plant.

The water passing through the filter is monitored by a couple of DFRobot TDS modules, a flow meter, and a DS18B20 temperature sensor.
