An Arduino-powered smart clothesline retracts when it rains (YL-83 sensor) or humidity is high (DHT11 sensor), using a 28BYJ-48 stepper motor and ULN2003 driver ...

This Automatic Water Level Indicator and Controller built with Arduino. ... Arduino Code for Water Level Indicator and Controller. The code is written in Arduino IDE. ... The pump motor starts ...

This project is a smart water level controller built using Arduino UNO, an ultrasonic sensor, and EEPROM for memory storage. The system automatically monitors the water level in a tank and controls ...

The system described here automatically regulates humidity by continuously monitoring ambient levels and switching the humidifier on or off as needed. It operates using real-time data from a humidity ...

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 automatic AC temperature controller is built around an Arduino mega development board. A DHT11 sensor is used to detect the ambient temperature and humidity. A TSOP1738 IR sensor is used to decode ...
