Development Of A Portable Incubator For The Detection Of Coliform In Water Using Iot

Ensuring clean and safe drinking water is a fundamental human right, yet many lack access, leading to waterborne diseases that claim lives globally. This project aims to create an affordable, portable coliform bacteria detection incubator. It employs a light-dependent resistor (LDR) and an IoT-enabled microcontroller (ESP32) to maintain ideal conditions for incubation. The system uses a Digital Humidity and Temperature (DHT11) sensor and heating element to sustain a 35-37°C temperature range, optimal for coliform bacteria growth. An integrated Liquid Crystal Display (LCD) records resistance and temperature data. Collected information is transferred to the microcontroller and streamed to the Blynk app for real-time monitoring. This innovation's portability and cost-effectiveness make it suitable for remote regions with limited access to laboratory equipment. Significantly, it holds promise for advancing low-cost, portable water quality monitoring systems, potentially enhancing public health.
