IntroductionWe can have integrated sensors which haselectronics and the transduction element together onone silicon chip. This complete system can be calledas system-on-chip (SoC).The main aim of integrating the electronicsand the sensor is to make an intelligent sensor, whichcan be called as smart sensor. Smart sensors then havethe ability to make some decision.Physically a smart sensor consists oftransduction element, signal conditioning electronic andcontroller/processor that support some intelligence in asingle package.DOES - PC 4. DefinitionA smart sensor is an analog /digitaltransducer combined with a processing unitand a communication interface.Smart sensors / Intelligent sensorare sensors with integrated electronics thatcan perform one or more of thefollowing function Data Conversion Bidirectional communication, Take decisions.

Microchip Technology Enables Smart Sensor Applications With NewFamily of the Worlds Smallest & Most Cost-Effective DSCsMicrochip Technology Inc. a leading provider of microcontroller and analog semiconductors,today announcedthe dsPIC33FJ12GP family of Digital Signal Controllers (DSCs), which are uniquely suited for a new class of Smart Sensor applications. Because they are the worlds smallest DSCs (in 18- and 28-pin packages as small as 6x6 mm) and the lowest priced (starting at $1.99 each in 10,000-unit quantities), the 40 MIPS dsPIC33FJ12GP family enables a new class of sensor processing, dubbed Smart Sensors, which can enhance sensor performance and extend product life. DOES - PC 27. Key Features of Microchip DSC 40 MIPS performance in 6x6 mm packages 12 Kbytes of Flash and 1 Kbyte of RAM ADC w/ up to 10 channels, and user-selectable 10-bit or 12-bit mode 1 - UART, 1 - SPI and 1- I2C PortDOES - PC 28.
