Open Source Software for Sensor Placement Optimization Available for Download

CHAMA, the Sandia-developed Python package which can optimize sensor placement, is now available for download. Continuous or regularly scheduled monitoring can quickly identify changes in the environment. However, even with low-cost sensors, only a limited number of sensors can be deployed. The physical placement of deployed sensors, sensor technology, and operating conditions, can significantly impact [...]
