This book provides an overview of recent advances in the development of gas sensors for the electronics and healthcare industries that can lead to lifestyle enhancements. Existing challenges and future research directions for easy integration of fast, cost-effective gas sensors are addressed and discussed in this book.

Metal Detector app uses your devices magnetic sensor to measure magnetic field values and turns any Android into a real metal detector. Data is displayed in µT (micro Testla). 1µT = 10mG (milli Gauss). The magnetic field in nature ranges from 25 to 65 µT (0.25 to 0.65 G). Any higher measurement is an indication of metal in the area. When there is metal in the area, magnetic field increases. App works best detecting ferromagnetic materials, such as iron and can’t detect non-ferromagnetic materials such as aluminum. App works best detecting metals up to 15cm away.

At a time when resources are scarce, not every crime may be investigated as fully as is desirable. Police generally use experience to guide their case screening. This volume demonstrates a new, research-based approach, exploring innovative research on crime solvability as a factor for crime investigation and prevention.
