THE PROBLEM

Railway Sanitation is
Broken Today

India's railways carry over 23 million passengers daily. Yet toilet monitoring remains entirely manual — reactive, inconsistent, and often too late.

23M+
Passengers travel daily on Indian Railways — many suffering poor sanitation with no real-time solution in place.
0
Automated real-time odour detection systems exist in standard railway coaches today.

The core issue: Current cleaning is reactive — staff only respond after passengers complain. Our solution shifts this to proactive, sensor-driven maintenance — cleaning before passengers ever notice a problem.

💨
Undetected Foul Odour
Bad odors develop inside train toilets and go undetected for hours, causing extreme discomfort for passengers — especially in premium coaches where expectations are high.
💧
Empty Water Tanks
Water tanks frequently run dry with no alert mechanism, leaving toilets non-functional for long stretches of the journey before staff are even notified.
📋
No Visibility for Staff
Cleaning teams have no centralized view of toilet conditions across coaches. Without real-time data, prioritization is impossible and maintenance is inefficient.
🌍
Impact on Tourism
For international travelers, hygiene standards are a critical deciding factor. Poor sanitation in coaches harms India's image as a destination and affects railway revenue.
HOW IT WORKS

Four Steps to Smart Sanitation

A hybrid event-driven and threshold-based control system that detects, responds, and reports — all automatically.

🔍
Sense
MQ-series gas sensors continuously measure odour levels. Ultrasonic sensors monitor water tank depth in real-time inside each toilet compartment.
⚡
Respond
When odour crosses the threshold, ESP32 automatically activates exhaust fans and triggers the solenoid valve for a spray-and-flush cycle on the floor.
📡
Alert
The master ESP32 sends SMS alerts to maintenance staff when water levels are critically low or odour remains high after the automated cleaning cycle.
📊
Monitor
All four toilets per coach are displayed on a real-time web dashboard — odour ppm, water %, fan/valve status, LED indicators, and voice alerts via DFPlayer.
THE TECHNOLOGY

Built on Proven IoT Hardware

Every component is chosen for reliability, affordability, and scalability across India's vast railway network.

🧠
Dual ESP32 Architecture
A master ESP32 manages the web dashboard, cleaning triggers, and SMS alerts. A slave ESP32 monitors additional toilets and streams data over WiFi — scalable to any coach length.

👃
Odour Detection System
MQ-series gas sensors precisely detect hydrogen sulfide, ammonia, and other foul-smelling gases at parts-per-million accuracy. Threshold-based triggering ensures no false alarms.
MQ Sensors PPM Threshold Event-Driven
💧
Water Level Monitoring
Ultrasonic distance sensors mounted inside water tanks measure depth continuously. When levels drop below a safe threshold, the system generates an alert before the tank runs dry.

💨
Automated Ventilation & Spray
When odour is detected, the microcontroller triggers exhaust fans to ventilate and opens a solenoid valve connected to a floor sprinkler — cleaning without human intervention.

📲
SMS Alert System
Instant SMS notifications are dispatched to railway maintenance personnel when critical conditions are detected — water shortage, persistent odour, or system faults — ensuring rapid human response.
SMS Gateway Multi-recipient Instant Dispatch
📊
Real-Time Web Dashboard
Railway staff can monitor all four toilets per coach from any device — odour levels, water percentage, fan and valve status, LED indicators, and voice alerts via the DFPlayer audio module.

STARTUP STRATEGY

Scalable from Premium to Network

We deploy first in Vande Bharat, Tejas Express, and AC coaches — proving value where expectations are highest, then scaling to the entire fleet.

🚆
Phase 1 — Premium Coaches
Target Vande Bharat, Tejas Express, and AC coach segments where hygiene standards are critical and maintenance budgets exist. Build proof of concept and gather performance data.
🌐
Phase 2 — Network Rollout
Modular hardware design allows one master node per coach, connected to a central cloud platform. Railway authorities get fleet-wide sanitation monitoring across entire routes.
🏗️
Phase 3 — Beyond Railways
The same platform adapts to metro trains, airports, bus stations, and public sanitation facilities — opening a significantly larger addressable market for CleanSense AutoSan.
