Home Automation System
You can create a cost-effective home automation system using Arduino Uno microcontroller and a Bluetooth/Wi-Fi interface. These devices can be interfaced with bluetooth/Wi-Fi software and be connected to the home devices. With tons of interfaces compatible with Arduino, devices like lamps, A/C, and refrigerators can be controlled with ease.
The world of lighting is going to see a lot more sensor lighting in the future. LEDs are reaching maturity at this point in their development cycle, so new ways of reducing energy consumption are being developed. LED lighting does consume less energy , but sensor lights are becoming a more efficient way to save more energy. There are two types of sensor light:
Motion sensor light
Motion sensors respond to movement. They detect movement accurately by using IR radiation, which indicates the temperature of things. The period when the light will switch on after motion can be adjusted.
Daylight sensor light
A daylight sensor measures the amount of natural light in an application area. The sensor can be configured to switch on or off as per the intensity of light For instance, when it gets dark outside, the lights will automatically switch on.
Temperature and humidity monitor
Temperature and humidity play an important role in household comfort. A thermo-hygrometer is a device that helps to track temperature and humidity. You can create a cost-effective, reliable and efficient system thermo-hygrometer using Arduino.
Obstacle avoider robot
An Obstacle Avoider robot is an autonomous gadget that can detect obstacles in its path and dodge them by moving in a different direction. This design enables the robot to move in an unfamiliar area while avoiding crashes, which is a major need for any autonomous mobile robot. There are numerous products that can be built on obstacle avoiding robots. One example is an automatic vacuum cleaner.
You can create an Obstacle Avoiding Robot with the Raspberry Pi and the PIC microcontroller as well as with an ultrasonic sensor and Arduino. In this case, an ultrasonic sensor is used to detect obstructions in the route by computing the distance between the robot and the obstacle.
