How to make a car accident alert system using MSP430 and GPS module

Here we build the same project again, but this time using the MSP430 launch pad and vibration sensor to detect vehicle accidents. Therefore, this project will also introduce the interface of the vibration sensor to the MSP430 launchpad. Here the vibration sensor module detects the vibration of the vehicle and sends a signal to the […]

Circuit design of portable heart rate measurement system based on MSP430

The HRV measurement system is similar to the heart rate measurement system of common fitness equipment. There are two common techniques for measuring heart rate: one is based on electrocardiogram (EKG) and the other is based on optical pulse pickup (as in pulse oximeter system). EKG is the most commonly used technology because it can […]
