External ThermistorThis equation can be used for any of the external channel of LRTH-1 data logger. The logger hasseven external thermistor channels that can accommodate any kind of thermistors.The key parameters in this equation are a, b and c coefficients that can be obtained from thethermistor manufacturer. You may change them based on the thermistor type you are using.//A custom equation for thermistor temperaturepublic double ExtThermistor2(double Input){//digit value must be 65534double dig_range = 65535;//load resistor must be 10000 ohmdouble load_resistor = 10000;double a, b, c, lgr, Output = 0;//different thermistor will have different a, b, c valuesa = 0.001028444; ;b = 0.000239244;c = 0.000000156;Output = CurrentChannel.DigitValue;if (Input >= dig_range)Output = dig_range - 1;if (Input < 1)Output = 1;double Rt = load_resistor * Output / (dig_range - Output);lgr = Math.Log(Rt);Output = 1f / (a + b * lgr + c * lgr * lgr * lgr) - 273.15f;}return Output;Previous Hour AverageThis equation can be used to calculate the averaged value for the previous hours. It can be easilymodified for a day or other time frame averages.DateTime CurrentTime;bool FirstIn = true;int HourIndex = 0;double AverageValue = 0;double SumValue = 0;int PreviousHour = 0;//Equation to calculate the average value of the previous hourpublic double HourAverage(double Input){//first time get in this function, initialize some variables.SiteView User’s Manual – Microedge Instruments Inc. 192/200
if (FirstIn){FirstIn = false;SumValue = Input;AverageValue = Input;PreviousHour = this.StartTime.Hour;CurrentTime = this.StartTime;}else{CurrentTime = CurrentTime.AddSeconds(this.SampleInterval);if (CurrentTime.Hour != PreviousHour){PreviousHour = CurrentTime.Hour;AverageValue = SumValue / HourIndex;SumValue = 0;HourIndex = 0;}}SumValue += Input;}HourIndex++;//Average value of the previous hour.//Note: the first hours value is always the first readingreturn AverageValue;The following figure illustrates the result after the above equation is applied:Note the red curve is the hour average of the black curve.SiteView User’s Manual – Microedge Instruments Inc. 193/200
