Week 7 (9.05)

Every group presented the Stage one of project demonstration to the class yesterday. The stage one is about what have we done after the initial report and presentation. My group presented all the things we have done, including the components, design, technical information and calculations. We also describe the further steps we are going to do. The big problem troubling us is the component price. We have to use the temperature sensors to monitor the temperature of brake rotor in our project. But, the brand new one price is around USD 200 to USD 300.It is too expensive for us, obviously we can not afford.Roman suggested us to look for a second hand temperature sensors. Or we can buy a cheap non-contact infrared temperature sensor for our project.The infrared temperature sensor is cheap, the price is around NZD 15 to NZD 30 on the Ebay.The problem is that how can we get the signal from this sensor.
