Our goal was to create a device to effectively notify drivers of off-road vehicles when they are in danger of rolling over. By using an accelerometer to measure the tilt of the vehicle, we created a device to warn drivers visually and audibly about their risk of rollover. Two banks of LEDs, corresponding to either a left or right tilt, and a speaker that sounds at an increasing frequency as the severity of the tilt increases, provide drivers with sufficient warning about when they are in danger of rolling over. The MSP430 is used to determine when the speaker and LEDs are triggered. Testing has shown that the device provides clear notification about a vehicle's chance of rollover; however, additions could be made to increase the product's functionality.
