EcoWatts: An IoT-Driven Platform for Chemical Wastewater Sensing and Sustainable Power Generation

Author : Zubin Dhanjisha Daruwala

Abstract :Here is a complete hardware-level analysis of a chemical waste monitoring system based on ESP32. Multiple modules like gas (MQ135), pH, temperature (DS18B20 / MAX31865), and flow (YF-S201) are interfaced with human-readable interfaces like an OLED display and GSM-based alerting mechanisms. Hardware integration, calibration processes, and response logic are focused on. System testing was conducted in laboratory conditions, wherein pre-determined levels effectively initiated real-time remediation measures to ensure smooth and fault-free operation.As a complement to monitoring, this research proposes a new system of energy recovery using chemical wastewater as a steam turbine-based electricity generation feedstock. Other complementary technologies like anaerobic digestion, waste heat recovery, and chemical-to-thermal energy conversion are also addressed. Application of these approaches to steam turbine technology exhibits their prospects for enhancing technical effectiveness while providing environmental sustainability in energy generation
