INTRODUCTION The electronics distribution industry is inherently a volatile one because it is based on technologies that are constantly evolving and improving as time passes. The industry has already survived three major technological revolutions and can probably be expecting another one in its long-term future. These "revolutions" usually concern the refinement or replacement of a component that is fundamental to all electronic circuitry. While demand for related component parts remains relatively

This block contains the LM35 sensor. It receives 9V supply from a battery and delivers an output voltage signal that ranges between 0 and 500 mV depending on temperature‚ 0V at 0ºC and 500mV at 50ºC increasing linearly in between. It may deliver more than 500 mV when the temperature is higher than 50ºC ‚ but it is useless since the conditioning system has a ceiling temperature of 50ºC beyond which sticks displaying as if it was 50ºC. It has a RC damper of 1uA capacitance and 100Ω resistor connected
