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}} 73 73 $$ 74 74 R_T = R_f \frac{V_{out}}{V_{in} - V_{out}} 75 75 $$ 76 -{{/mathjax}} ))) 77 77 {{/mathjax}} 76 + 77 +(% class="wikigeneratedid" %) 78 +where: 79 + 80 +* {{mathjax}}$$R_f$${{/mathjax}} = The resistance of the upper resistor, which in this case is 4.7k Ohms 81 +* {{mathjax}}$$V_{out}$${{/mathjax}} = Voltage measured by the microcontroller 82 +* {{mathjax}}$$V_{in}$${{/mathjax}} = Supply voltage of the voltage divider, which in this case is 3.3 Volts 83 +* {{mathjax}}$$R_T$${{/mathjax}} = Resistance of the thermistor in Ohms 84 + 85 +=== Suspension Displacement Sensor === 86 + 87 +=== Oil Temperature Sensor === 88 + 89 +=== Cooling Sensor === 90 + 91 += Design = 92 + 93 +== Schematics == 94 + 95 +== Mechanical == 96 + 97 +== Bill of Materials == 98 + 99 += Cost = 100 + 101 += FAQ = 102 + 103 +
