# Introduction The Boomerang 3 system can use many different types of sensors. This manual presents the installation and maintenance of a Satellite 2 (S2) radio network. The S2 Radio system was developed in 2004 and thousands of these nodes still operate in numerous B2 and B3 monitoring systems. S2GW gateway was developed in 2022 to enable a migration of the existing S2 installation from B2 to B3 systems. The Boomerang 3 system is an automatic system logging and monitoring physical parameters like temperature, relative humidity, pressure etc. It makes monitoring and quality assurance of your laboratory simple, precise, and efficient.
