Continuous or regularly scheduled monitoring has the potential to quickly identify changes in the environment. However, even with low-cost sensors, only a limited number of sensors can be used. The physical placement of these sensors and the sensor technology used can have a large impact on the performance of a monitoring strategy.

Chama is a Python package which includes mixed-integer, stochastic programming formulations to determine sensor locations and technology that maximize the effectiveness of the detection program. The software was developed to design sensor networks for water distribution networks and airborne pollutants, but the methods are general and can be applied to a wide range of applications.
