The Boil-over Alert should have a sensor that senses the liquid level of the soup and an indicator to give her alert on time. I chose to use a soil moisture sensor instead of a temperature sensor because the soup flowing over the pot can happen before, during or after boiling, so a soil moisture sensor will be more accurate to capture the boil over moment. Both a LED light and a text message will be indicators so that she can be alerted no matter where she is at home and whether she is paying attention on something else or not. After she skim off the foam, she should press a button to turn off the LED light.
