A network of middle to low latitude particle detectors called SEVAN (Space Environmental Viewing and Analysis Network) is planned in the framework of the International Heliophysical Year (IHY), to improve fundamental research of the space weather conditions and provide possibilities to perform short and long-term forecasts of the dangerous consequences of the space storms. The network will detect changing fluxes of the most of species secondary cosmic rays at different altitudes, latitudes and altitudes those constituting powerful integrated device in exploring solar modulation effects. Based on our experience with data analysis of multivariate time-series from particle detectors located at Aragats Space-Environmental Center in Armenia we designed and fabricated several new-types of particle detectors measuring charged and neutral component of secondary cosmic rays. In order to keep the instruments inexpensive the options are kept flexible by using modular designs. The price of a fully autonomous single unit, with facility to send data to the internet will not exceed $20,000 US, so that the network of nations involved in space research can be significantly expanded to enable them to participate in IHY. At any time one can cascade these single units to achieve additional functionality. Like the world network of neutron monitors, the new monitors will measure the neutron fluxes and in addition they will measure charged particle fluxes with different energy thresholds, thus allowing the investigation of additional populations of primary ions. These units plan to be deployed at universities and research centers of the developing countries to perform survey and monitoring of most dangerous space storms and to introduce the space research to new generations of students and researchers.
