During this Covid-19 era, many of us spend most of our days hunched over a desk, leaning forward looking at a computer screen, or slumped down in our chair. If you’re like me, you’re only reminded of your bad posture when your neck or shoulders hurt hours later, or you have a splitting migraine. These problems appear gradually if the person repeatedly assumes incorrect postures for a prolonged period of time. Studies have indicated that an incorrect posture can lead to a host of ailments, including exacerbating arthritis, breathing difficulty, headaches, among others.

What it does

Posturino (Posture Monitoring hardware wearable device)

A wearable IoT device for the people who are doing day-to-day works and also working in front of the computer. Alarm if the proper posture angle is not maintained.

How we built it

Material Required

Ball Switch Module

Arduino UNO



Resistor - 10k ohm


Connecting wires (M-M)

This is a Mercury switch-based tilt sensor module that gives high at its output pin when tilted. It requires a 5V of DC input. It’s a four-terminal device consist of VCC, GND, A0, V0. It has a glass tube consist of two electrodes and a liquid mercury ball. The liquid mercury ball closes and opens the circuit when inclined in a particular direction.

whenever the Tilt sensor is inclined beyond a particular angle the Output of the tilt sensor gets HIGH. This output is read through Pin. Therefore, whenever Pin is HIGH, it turns ON the LED and Buzzer and gives an alarm.

Accomplishments that we're proud of

The main purpose of this project is to develop a simple, economical, and effective means to optimize the body posture under cases where modification in the tasks or work environment can prove very costly, unsafe, and difficult.

What we learned

IoT wearable devices architecture.

What's next for Posturino

We wanted to make this device more small and compatible but due to the lockdown, there were no shops opened so just made use of what was available to us.

We will look for more solutions and will try to create more cost-effective devices in order to maintain proper health well-being.

This device can be more compact if we use Arduino nano instead of UNO.
