Week #8: June 30th - July 6th

Group Log

The group met again on Wednesday to bring together everyone's individual work and perform the first test of the complete prototype. The valve regulator processes were simulated and the serial monitor of the MCU was observed, as well as output functions of the valve regulator.

The temperature sensor was tested using a heat gun and increased beyond 120°F. Once the sensor reached 120°F, the serial monitor displayed a scald warning and automatically shut the hot water valve to push cold water out.

The duty cycle trigger was connected to the "cool command" to test the valve's ability to quickly modulate the valves to reach a cold output quicker. The trigger was also connected to the opposite to test the valve's ability to output hot water quickly.

The state of charge sensor was connected to read a "dummy" value of the battery. The voltage divider circuit was not yet put in place, but a quick test circuit was constructed to validate a successful state of charge observation.

The moisture sensor was triggered to simulate a leak and the valves closed automatically and a leak warning was displayed on the serial monitor.

Flow rate was reconfigured and displayed on the serial monitor when a flow was simulated.

Upon flow simulation, the serial monitor displayed a "wake" signal to show the generator was charging the battery.

The bluetooth connection was working properly and efficiently until the flow rate sensor was implemented. Many attempts to reconnect the valve and thermostat were made with no success. The problem was troubleshooted and tested over and over until the discovery was made later in the evening. The problem was addressed and awaits further testing.
