Device::USB::PCSensor::HidTEMPer::NTC::External(3pm) User Contributed Perl Documentation Device::USB::PCSensor::HidTEMPer::NTC::External(3pm) Device::USB::PCSensor::HidTEMPer::NTC::Internal - The HidTEMPerNTC external sensorVERSIONVersion 0.02SYNOPSISNoneDESCRIPTIONThis is the implementation of the HidTEMPerNTC external sensor. CONSTANTS o MAX_TEMPERATURE The highest temperature(150 degrees celsius) this sensor can detect. o MIN_TEMPERATURE The lowest temperature(-50 degrees celsius) this sensor can detect. o INITIAL_GAIN The initial gain value used to calculate voltage returned o CALIBRATION_VALUES Values used to calculate Volt7705Calibration METHODS o new() Returns a new External sensor object. o celsius() Returns the current temperature from the device in celsius degrees. The formula used to calculate value based on a calibrated key value is created using the Eureqa tool from Cornell Computational Synthesis Lab, http://ccsl.mae.cornell.edu/eureqa. Resulting in the use of this formula instead of the provided number list: f(y)=66.7348/(66.7275/(67.8088 - 9.70353*log(0.000251309 + y*y)) - 0.21651) If you find another formula that is more accurate please drop me a line. The data used can be found in the source code of this file.INHERIT METHODS FROMDevice::USB::PCSensor::HidTEMPer::SensorDEPENDENCIESThis module internally includes and takes use of the following packages: use Carp; use Time::HiRes qw / sleep /; use Device::USB::PCSensor::HidTEMPer::Sensor; This module uses the strict and warning pragmas.BUGSPlease report any bugs or missing features using the CPAN RT tool.FOR MORE INFORMATIONNoneAUTHORMagnus Sulland < msulland@cpan.org >ACKNOWLEDGEMENTSThis code includes findings done by Robin B. Jensen, http://www.drunkardswalk.dk, when converting the received hex values into volt.
