• Potential CVT Belt Temperature Sensor
• Obvious con of being $350

• Cheaper alternative to the one linked above
• Two cons, it has a small display so might be hard to read at high speeds as well as it unfortunately causes cancer and reproductive harm.

• Wireless Temp Sensor article, potentially can help with us connecting the temp sensor to the Aux Daq.

Look into the numbers, look at the data sheet. Look how it would work inside the CVT case. 100 degrees Celsius. Look how to repurpose a covid temperature scanner.

CVT Primary Belt runs at 240 F or 115.5 C CVT Case / Ambient Environment runs at 120 F or 48.88 C

Ask the mechanical team about if we can orientate this temp sensor into the case, and drill holes on the side to put the wires through it.

We are able to mount this sensor in the case. Currently checking the rulebook on CVT case mounting, we just need to figure out how we will orientate the wires. @Vishnav03

Video about the infrared sensor.

With reference to this photo, the producer uses a 12 V battery to power both the Infrared sensor and their HUD. We believe that only a small amount of that voltage powers the sensor. Teensy can handle a maximum of 5 volts.

Recieve PCB and Sensor. Andrew is working on cadding mount for sensor, Evan is trying to test if the code for the sensor works

[Vishnav03]

CAD done, Solder done, need to get the code working
