1. Picking the input device: Thermistors¶

We have a large range of input devices that we can choose to manipulate for this week

  • switch
  • magnetic field
  • potentiometer
  • step response
  • temperature
  • light
  • motion
  • distance
  • location, time
  • acceleration, orientation rotation
  • sound
  • vibration
  • force
  • angle
  • pressure
  • pulse
  • air pollution
  • gases

Thermistor

I choose the thermistor as the input device of this week. The demonstration video of the thermistor that Neil show us was the most easy to understand for me.

đź’­

I did a brainstorming to visualize the real-life application of thermistor.

What is a thermistor? I imagine that it is a temperature sensor that receive heat and tranform the heat to analog signals… Maybe it’s not right, I’ll check this information later. A commun example for temperature sensor is Thermometer. Oh, we also can find temperature sensor in objects or machine where we need to control the temperature, like computer, smartphone, refrigerators, air conditioners, and water heaters… It’s so fascinating to find out that this little sensor is surrounding us in some way. But, I still don’t know what is a thermistor. Is it similar to a thermometer? The picture that Neil shows us seems like a resistor. A thermometer+resistor? What’s the point, and why it has been invented as an input devices for pcb?

What is a Thermistor?

Before reseach

A temperature sensor that receive heat and tranform the heat to analog signals

After reseach

A resistor that changes its value in function of the temperature. In other words, the resistance of this component changes with temperature.

I don’t know

I checked the electronic component’s stock of thermistor

Searched the reference NHQ103B375T10 on the web and found it.
