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 72 $$ 73 73 R_T = R_f \frac{V_{out}}{V_{in} - V_{out}} 74 74 $$ 76 +{{/mathjax}} ))) 75 75 {{/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 -The resistance R_T can then be put into this 86 - 87 -=== Suspension Displacement Sensor === 88 - 89 -=== Oil Temperature Sensor === 90 - 91 -=== Cooling Sensor === 92 - 93 -= Design = 94 - 95 -== Schematics == 96 - 97 -== Mechanical == 98 - 99 -== Bill of Materials == 100 - 101 -= Cost = 102 - 103 -= FAQ = 104 - 105 -
