Touchless faucet
with door control
system for covid
As someone approaches an entrance with this mechanism,there is a
“Please wash your hands” message displayed by the LCD.
Once the person moves closer to the faucet, the ultrasonic sensor,
sensing proximity, sends a signal to the servo motor which in turn rotates
the pump.
As the pump is running, the LCD displays,
“Washing hands, please wait”, in case there is someone else waiting to enter.
Once done with hand washing, as the hands are withdrawn,
the pump shuts off and as a result the LCD displays, “Please proceed” a
nd the door is opened.

Face-Mask ATM
and
Reminder
The project is a proof of concept of a mask dispensing ATM that can be installed at homes to
remind people to take a mask before leaving or at the entrance of public facilities. When
someone comes into close proximity with the dispenser, a buzzer goes off and a text reminding
one to pick a mask is displayed. One can then pick whatever number of masks they require and
the buzzer will go off. In case of a low balance of masks, it will notify the user to refill.

Simple Pulse
Monitor
The pulse sensor module has a light that helps in measuring the
pulse rate. When we place the finger on the pulse sensor,
the light reflected will change based on the volume of blood
inside the capillary blood vessels.
This variation in light transmission
and reflection can be obtained as a pulse from the output of
the pulse sensor. This pulse can be then conditioned to
measure heartbeat and then programmed accordingly
to read as heartbeat count using Arduino. The heartbeat is then displayed
on the serial monitor which can later be used as a lie detector.

Stepper Motor
Control using
Blyk app
Blynk is a platform that allows you to quickly build interfaces
for controlling and monitoring your hardware projects from your
iOS and Android device. After downloading the Blynk app, you can
create a project dashboard and arrange buttons, sliders, graphs,
and other widgets onto the screen. Using the widgets, you can turn
pins on and off or display data from sensors.In our project, we are
going to control a stepper motor using the Blynk application.
In our project, we are
controlled a stepper motor using the Blynk application. Thiscould be replicated
to switch a fan in the house on and off. Open GitHub

Voice Controlled
Home Appliances
This is a project which is supposed to enable one to control
home appliances by use of voice commands communicated to the Google Assistant,
which then prompts the desired actions. In this case, we used voice commands
to turn an LED on or/ and off. This serves to make work easier,
and adds convenience, since it can be done remotely.

Automated
Door System
This project involves coming up with a proof-of-concept
automatic door system that helps reduce coming into contact
with contaminated surfaces, an example is, a door in a public place
, most especially during this day and age of Covid-19.
The door is automated in such a way that it opens once one
comes within range of the HC-SR04 Ultrasonic sensor.

Automated
Smoke
Detector
This smoke detector project is a proof of concept
that you can be able to capture and send data to the
cloud from NodeMCU using the Blynk App. It detects
smoke beyond a set threshold and sends a notification to the Blynk App.
The smoke sensor has been implemented before
in smoke alarms that go off and automatically;
trigger fire sprinklers that release water and a smoke alarm,
to alert the owner. It’s purpose is to save property and
life from an actual, full-burning fire.
