Product Description

The COVID-19 pandemic has radically affected life for almost everyone around the globe, and makers are no exception. With everyone being more careful of their interactions with humans and objects, personal hygiene has taken serious precedence over all other factors in public space. A lot of public places have hand sanitizers for visitors, but they need to be manually pressed. To avoid any contact at all, some no-touch hand sanitizer dispensers are commercially available, but they are expensive and most off-the-shelf commercial sanitizers cannot be automated. In this project, we create a contactless hand sanitizer dispenser that can be used for any press-to-release hand sanitizer available in the market.The project uses a simple discrete components. The system is adjustable to accommodate most sanitizer bottles.

6.IR REMOTE CONTROLLED FAN REGULATOR

Product Developed by : Mr. JebaAndroes.R, Mr. KaviPranesh.S – II Year –ECE

Product Description

The speed of a fan can be controlled by using IR receiver with the help of TV remote. Pulses from the IR receiver module are applied as a trigger signal to 555 timer via LED and a resistor. As the width of the pulse decreases, firing angle of the TRIAC increases and speed of the fan also increases. Thus the speed of the fan increases when any button is pressed on the remote control.
