What It Does

The CWS device is a multi-parameter water monitoring system that is capable of reading from four probes at once. Real-time data is displayed on the unit's Liquid-Crystal Display.

​

Our unit is modular due to our utilization of the I2C communication protocol. This allows for additional sensors to be incorporated with ease.

​

This unit is intended for water quality monitoring and wirelessly transmits data to a ThingSpeak server for data visualization and logging. The CWS mobile application provides users with access to organized tank status data from almost anywhere.

Hardware

NodeMCU with ESP8266

The NodeMCU is a dev board that features the ESP8266 chip. This board is utilized for data centralization and sending data over Wi-Fi, it is capable of transmitting to nearby Wi-Fi connections up to around 100 meters.
