Proper humidity level in home for summer This sensor consists of a current source which flows through four diodes in series and the voltage drop across the diodes which is proportional to temperature can be measured by internally connecting the sensor to the ADC and determining the temperature based on the ADC value In this assignment the temperature sensor is used to create a simple thermometer application and to create an alarm should the sensor go outside the set value. Proper humidity level in home in winter Assignment Details 1) Determine the register settings needed to switch the sensor on and connect the temperature sensor to the ADC. Proper humidity level in house Using appropriate values for Vref+ and Vref- display the ADC count value on the 7 segment display. Proper humidity level in house canada 2) With reference to Microchip Application Note AN1333, “Use and Calibration of the Internal Temperature Indicator” (DS01333) determine an appropriate algorithm to convert from the ADC value to the temperature in degrees centigrade and implement it using a lookup table or otherwise.
