Week 5

FSRs are sensors that allow to detect physical pressure, squeezing and weight. They are simple to use and low cost.  This is a photo of an FSR.

Figure 1 : FSR sensor

The FSR is made of 2 layers seperated by a spacer. The more one presses, the more of those Active Element dots touch the semiconductor and that makes the resistance go down. FSR are basically a resistor that changes its resistive value (in ohms Ω) depending on how much its pressed. These sensors are low cost. I buy from myduino.com.my around RM25.00. 

I order this sensor and takes about 4 days to delivery. So nothing much i do this week. I just research about this FSR and cant wait to test it.
