Monitoring systems for temperature, humidity and other parameters can be complex, involving hundreds of sensors in a variety of applications. One of the most important decisions in selecting or adding to a monitoring system is choosing the connectivity method that will allow the sensors to speak to a central processing unit. Decisions on connectivity are dependent upon several factors, including: data integrity requirements for regulatory purposes, logistical concerns such as access points for transmitters, and existing network infrastructures. In this article, we describe the most common wireless methods of connecting sensors to a monitoring system and offer eight considerations for selecting a method best suited to the application.
