About

Absortech is a project developed by IEEE UFF to achieve the free distribuition of menstrual pads with the help of digital monitoring.

The pads are stored in boxes and, through a distance sensor which sends the data to a website, tells if the box is empty or full (or somewhere in between). This way, it's easy to monitor when it's time to refill it without constant manual checking.

Plus, the website is also meant for people who need a pad to go to where the box is guaranteed to not be empty, which avoids wasting time and frustration.

Moreover, Absortech will distribute these items free of charge, looking to help with menstrual hiegiene.

Technologies used

Features

• Check how full the boxes are
• See location of boxes

Setup

To start the entire environment using Docker, run the following command:

docker network create absortech-network
docker compose -f docker-compose.dev.yml up -d --build

Project Structure

The imagem below provides an overview of how Absortech works

Build your own

In order to replicate this yourself, make sure you have an ESP32 and the HC-SR04 sensor and follow this schematic:

When you run ultrasom.ino the distance (which is measured in cm) is correct and ajdust the empty/full calculations to whatever works best for you.

Each ESP32 must be registered as a Dispenser in Django and configured with the corresponding DISPENSER_ID in iot/ultrasom.ino. The current sensor reading payload format is:

{
  "dispenser_id": 1,
  "distancia_cm": 10.5
}
