Spectra Symbol 12.7 mm Circular Force sensor This is a force-sensitive resistor with a round, 0.5? diameter, sensing area. This FSR will vary its resistance depending on how much pressure is being applied to the sensing area. The harder the force, the lower the resistance. When no pressure is being applied to the FSR its resistance will be larger than 1M?. This FSR can sense applied force anywhere in the range of 100g-10kg. Two pins extend from the bottom of the sensor with 0.1? pitch making it bread friendly. There is a peel-and-stick rubber backing on the other side of the sensing area to mount the FSR. Just Connect a resistor to form a voltage divider and measure the voltage at the junction to find the force applied. These sensors are simple to set up and great for sensing pressure, but they aren’t incredibly accurate. Use them to sense if it’s being squeezed, but you may not want to use it as a scale. This sensor can be easily interfaced with Microcontrollers, Arduino Boards, Raspberry Pi, etc. using an Analog-Digital Converter (ADC).

Speech Recognition Module The Voice Recognition Module can recognize as many as 15 voice instructions and be suitable for most cases involving voice control. It receives configuration commands or responds through a serial port interface. The Speech Recognition Sensor Module can control cars or other electrical devices by voice. It can store 15 pieces of voice instruction. Those 15 pieces are divided into 3 groups, with 5 in one group. First, we should record the voice instructions group by group. After that, we should import one group by serial command before it can recognize the 5 voice instructions within that group. If we need to implement instructions in other groups, we should import the group first. This module is speaker-independent. If your friend speaks the voice instruction instead of you, it may not identify the instruction.
