Accelerometers and gyroscopes are used for various safety features in modern vehicles. In this article we used Parallax LISY300 Gyroscope Module to measure Gyroscope PCB rotation speed and current position. The complete project is available for download at the bottom of the page. Results turned out to be better than we expected. An error is only few degrees in 10 full circles turn. You can read more about this sensor in this Featured components - LISY300 Gyroscope Module article.
Accelerometers and gyroscopes are used for various safety features in modern vehicles.Possible appliance of such sensor is very wide, from crash detection for airbag release to electronic stability control systems, allowing the car to aid the driver during evasive maneuvers at speed. Gyroscopes can also be used with navigation systems to provide fine location information and help when there is no GPS signal, e.g. in tunnels. We used this sensor in
A gas detector is a device which detects the presence of various gases within an area, usually as part of a safety system. This type of equipment is used to detect a gas leak and interface with a control system so a process can be automatically shut down. A gas detector can also sound an alarm to operators in the area where the leak is occurring, giving them the opportunity to leave the area. This type of device is important because there are many gases that can be harmful to organic life, such as humans or animals.
LABVIEW is data flow oriented programming language. It gives engineer many possibilities to make complex program in few minutes. Down side is that it is usually used with NI data acquisition boards which are expensive. In this example we will use data received from cheap microcontroller via COM port of PC to process and display data.
