Wireless versus wired sensors

April 5, 2019
The advantages and disadvantages of each sensor type.

When selecting vehicle sensors, sometimes the decision between wired and wireless sensors is made for you. For example, wired sensors don’t work on the tire for TPMS applications, or on an engine belt, because of the constant rotation and nature of the use. For applications such as these, wireless sensors are the obvious choice. 

With other applications, fleets may have an option between wired or wireless sensors. There are benefits and drawbacks to each, says Lee Alexander, director of product management, IoT platforms, STEMCO. “Wireless sensors have a quicker installation, but the battery power means it has a limited life. For wired sensors, they’re powered, but they often require more time for installation.”

Another consideration is the speed of connection that is needed. Typically, for applications that require a high speed of information transference, a wired sensor is better. Although wireless Bluetooth connectivity is improving, it may sometimes struggle with latency and interference issues in some applications.
