The SenseAnywhere AiroSensor X ER model 20-20-43 is like the popular AiroSensor T ER model
20-20-31 with in addition an IP67 class connector featuring the digital SenseAnywhere Bus
(SAB). The SAB is a hot pluggable interface which provides power and data communication to
SAB external sensors from SenseAnywhere. Due to the nature of this interface the external
sensors can be tested and calibrated as an individual device providing a big advantage over
analogue interfaces where the sensor and measuring device always need to be calibrated as a
pair.
