01 / 10Active

PIR Motion Sensor

Purpose
Detects user entry automatically without physical contact.
How it works
Uses passive infrared sensing to detect body heat and movement.
Benefits
Hands-free activation improves hygiene and energy efficiency.
Smart automation
Triggers lighting, exhaust fan, audio guidance and smart systems automatically.
Accessibility impact
Helps elderly and disabled users without requiring switches or manual interaction.
02 / 10Online

Audio Guidance Speaker

Purpose
Provides spoken guidance so users never have to read or touch a screen.
How it works
ESP32 streams pre-recorded multilingual audio cues through a clarity-tuned speaker.
Benefits
Improves usability for visually impaired and first-time users.
Smart automation
Activates contextually based on PIR entry, SOS press and exit detection.
Accessibility impact
Critical for visually impaired and elderly users navigating the cabin independently.
03 / 10Standby

Auto Air Freshener

Purpose
Keeps the cabin smelling clean between users.
How it works
A solenoid-actuated aerosol releases a measured burst on cycle completion.
Benefits
Continuous freshness without staff intervention.
Smart automation
Triggered by load sensor exit signal, throttled to avoid over-spray.
Accessibility impact
Removes the need to manually press a freshener button.
04 / 10Armed

Emergency SOS Button

Purpose
Provides emergency assistance for users in distress.
How it works
Pressing the SOS button sends an emergency alert to maintenance and security.
Benefits
Improves public restroom safety and emergency response time.
Smart automation
Triggers facility alarm, PAS announcement and dashboard notification instantly.
Accessibility impact
A critical safety feature for elderly and disabled users.
05 / 10Calibrated

Left Load Sensor

Purpose
Confirms safe user posture during use.
How it works
Strain-gauge load cell measures distributed weight on the left foot pad.
Benefits
Detects falls, slips and unusually long stays in real time.
Smart automation
Pairs with the right pad to trigger auto-flush and freshener on exit.
Accessibility impact
Silently watches over elderly users without invading privacy.
06 / 10Calibrated

Right Load Sensor

Purpose
Mirrors the left pad to confirm balanced posture.
How it works
Strain-gauge load cell streams weight readings to the ESP32 hub.
Benefits
Enables fall detection and accurate exit triggering.
Smart automation
Combined readings start the post-use cleaning sequence automatically.
Accessibility impact
Provides safety-net monitoring for users who can't call for help.
07 / 10Connected

ESP32 Controller Box

Purpose
Acts as the brain — orchestrates every sensor and actuator.
How it works
ESP32 reads sensors over GPIO, runs decision logic, and streams telemetry over Wi-Fi.
Benefits
Single low-power hub replaces a roomful of dedicated controllers.
Smart automation
Runs all timing logic, escalations and cloud sync without manual setup.
Accessibility impact
Coordinates every assistive feature behind the scenes.
08 / 10Auto

Smart Ventilation System

Purpose
Maintains fresh airflow and an odor-free environment.
How it works
Exhaust fan activates based on real-time gas sensor readings.
Benefits
Improves air quality and cabin comfort.
Smart automation
ESP32 modulates fan speed and runtime automatically.
Accessibility impact
Creates a healthier environment for sensitive and elderly users.
09 / 1012% full

Smart Bin

Purpose
Touchless waste disposal with fill-level reporting.
How it works
Ultrasonic sensor opens a motorized lid and tracks remaining capacity.
Benefits
Reduces cross-contamination and dispatches cleaners only when needed.
Smart automation
Lid auto-opens on hand approach; fill level is published to the dashboard.
Accessibility impact
Hands-free disposal for users with limited dexterity.
10 / 10Clear

Drainage & Floor Cleaning Channel

Purpose
Automatically sanitizes the restroom floor after the user exits.
How it works
Two flat-fan nozzles spray pressurized water across the floor toward the trench drain.
