Monitoring of temperature using smart sensors based on CAN architecture

In this work is presented the implementation of smart sensors for monitoring temperature and for communicating among them self using the protocol CAN (controller area network). A smart sensor has the capacity to make decisions based on data and command received. These decisions can include the control of an actuator, the sending of information for a controller in communication to other smart sensor that can carry out a wished function. CAN is a protocol of serial communication that allows the control of systems distributed in real time with high level of safety. This protocol was developed in the nineteen eighties in order to decentralize vehicle control systems because their characteristics CAN are being used currently in several areas.
