0 Figure 2 Thermistor measurement circuit Activity 1 (2 marks) Show that the value of the thermistor resistance can be determined according to the equation TH Rehermister X ... (1) In practice, a microcontroller reads the value of nu via an analog to digital converter (ADC) and applies equation (I) in its control code to determine the thermistors resistance value. The accuracy of the result will depend on: I The accuracy of Ro The accuracy of The accuracy of the measurement The microcontroller code will then either use a look-up table or approximate the look-up table using an equation (Steinhart-Harts equation that approximates the resistance temperature relationship in a thermistor to determine the ambient temperature Activity 2 (10 marks) Determine the value for Rier that will allow for maximum resolution accuracy) in the ambient temperature measurement The Arduino Uno ABC Matures a voltage from 0 to 3V. The voltage is converted into a 10 bit binary number-1024) so the smallest voltage increment that can be measured is 5/10244.my Choose VSV We expect ambient temperature to be in the 200-30C range Use the data sheet typical thermiste resistance values, and your chosen value for to determine how accurate the digital printation of ambient temperature will be Thermocouple Measurement MacBook W Holo D ZTP-135SR datasheet (page 2 of 4) Thermopile Chip Thermistor Resistance (R-T Table) Parameter Am Limit Una Condition Tambrai Rmina 091 ERT Rount 79 7159 ME 9873 7447 mm 18x18 1A 14 0707 -15 -10 -5 5454 5665 5245 4013 4345 4188 3241 42 60 51 C 3126 Chips Diaphragm See Active Area Internal Restance Resistance Responvity Responsivity TC Noise Voltage NEP 2615 5 0.12 81 N/ WW N/C SOOK 1 20 1918 62 -0.10 2051 2527 1985 1569 1245 1519 1210 20 128 1030 0.51 RM5.25" SOOK THE SOOK.
