Weekly Progress
Over all
 The information we obtained from the design team is a group of us to focus on the
"Getting Started Product to bring appreciate". The design team has thought up
refreshment at the start of something good. Is assigned to an engineer to find out about
the warning, a wake up feeling relaxed, both in the form of light, noise and vibration.
 The engineering team is going to find out about the various sensors such as light
sensors, sound sensors, etc., for information about supply in various forms, such as
coin-cell battery AA battery charge , etc., and find out about the switch that there should
be a switch, press it, a touch screen, touch, etc., to support the product of the design
team.
Enginearing knowledge
 vibration mode, This function will work with vibrating
motors. The vibration of the motor The weight on the motor
shaft when the shaft rotates it causes an imbalance in
counterweight. Thereby causing the vibration.
 Temperature Sensor, To measure the temperature
variations of the analog signal into a voltage. Digital signal.
Relative to the temperature sensor is formed by 3 major types The internal structure
1.Thermocouple is a device used to measure temperature is the of the motor.
temperature voltage.
2.Resistance Temperature Detector (RTD) temperature sensor is used to change the
resistance of the metal.
3.Thermistor resistance is a device that can change resistance when exposed to heat.
Engineering Analysis
Strong Point
- I have knowledge about the process of temperature sensors and vibration mode.
- "Getting Started Product to bring appreciate"
Week Point
- Temperature sensors. Measured value is less linear, more expensive.
Next Week Job
- I will to learn more application about temperature sensor and vibration mode.
