Labs Idea #5: Windshield Ice Detection
In areas where the temperature drops close to freezing or lower during the night, the windshield of a car is very often covered with a layer of ice in the morning. Knowing if the windshield has ice allows a notification to be sent to the driver advising them to get to the car a little bit earlier to manually de-ice the windshield or, in a more automated car, the windshield to be automatically de-iced in the morning before the driver gets to the car to eliminate the wait. Since the formation of ice is dependent on very local conditions (see details below), a local sensor is necessary. The formation of ice can be estimated well with an RH/T sensor. This can be either an existing sensor in an anti-fogging module or a dedicated sensor.
