# Router Cooling Demo

The controller is configured to cool a temperature sensor (placed between a desk router and switch) to a specific temperature.

## Hardware Requirements

1. A Teensy Fan Controller (fe. [Breadboard](/teensy-fan-controller/hardware/breadboard.md), [Schmart Board prototype](/teensy-fan-controller/hardware/prototype.md), [Simple PCB](/teensy-fan-controller/hardware/simple-pcb.md))
2. One Teensy 3.x with headers (previously *flashed with Teensy Fan Controller*)
3. A Micro USB cable
4. One 12v power supply (up to 15V should be OK)
5. One PWM PC fan (80mm, 120mm, 140mm)
6. Wires

## Sensor and fan placement

* The temperature sensor is placed between the cases of a router stacked on top of a switch
* The fan is pointed at the router/switch
