A Low Cost Open Source Remote Monitoring System for Hospital Wastewater Management

Wastewater can be dangerous if not handled properly, e.g. it spilled out from the tank. Hospital wastewater hazard was even more damaging to environments and humans due to its chemical contents. Therefore, it is desirable to have monitoring system to prevent such incidents. In this research, remote monitoring of wastewater using low cost and open source IOT technology was implemented at Bali Mandara Hospital waste management facility. The system used ESP8266 microcontrollers and HCSR04 ultrasonic sensors to determine wastewater volume. Blynk IOT cloud server was used as the platform to collect and visualize the data online. The implemented IOT system showed robust performance as a monitoring system for hospital wastewater management.
