To find the temperature of the thermistor based on the voltage measure by the analog-to-digital converter (adc), the resistance of the thermistor needs to be calculated based on the voltage from a voltage divider. 70 70 71 71 {{mathjax}} 72 -(% style="font-size: 1.5em;" %) {{mathjax}}72 +(% style="font-size: 1.5em;" %)((( 73 73 $$ 74 74 R_T = R_f \frac{V_{out}}{V_{in} - V_{out}} 75 75 $$ 76 - {{mathjax}})))76 +))) 77 77 {{/mathjax}} 78 - 79 -(% class="wikigeneratedid" %) 80 -where: 81 - 82 -* {{mathjax}}$$R_f$${{/mathjax}} = The resistance of the upper resistor, which in this case is 4.7k Ohms 83 -* {{mathjax}}$$V_{out}$${{/mathjax}} = Voltage measured by the microcontroller 84 -* {{mathjax}}$$V_{in}$${{/mathjax}} = Supply voltage of the voltage divider, which in this case is 3.3 Volts 85 -* {{mathjax}}$$R_T$${{/mathjax}} = Resistance of the thermistor in Ohms 86 - 87 -The resistance R_T can then be put into this 88 - 89 -=== Suspension Displacement Sensor === 90 - 91 -=== Oil Temperature Sensor === 92 - 93 -=== Cooling Sensor === 94 - 95 -= Design = 96 - 97 -== Schematics == 98 - 99 -== Mechanical == 100 - 101 -== Bill of Materials == 102 - 103 -= Cost = 104 - 105 -= FAQ = 106 - 107 -
