CS1602: CUSTOM DATA ACQUISITION MODULE – SHAMPOO
Problem Statement
Develop data acquisition module for submersion in shampoo bottle. Module must be small size, light weight and completely undetectable by the user. Customer usage profile data to be used in product packaging design and manufacturing.
Solution
- Developed custom data acquistion hardware and software utilizing USB or Bluetooth communications for data download.
- Special software that allows the system to determine specific events like when the bottle is squeezed or dropped. (Actual data recorded from linked squeeze event, shown in image)
- Module measures customer usage data including internal ‘squeeze’ pressure, bottle orientation, acceleration from a drop event, temperature, and date and length of each event.
- Injection molded ABS enclosure with silicone gasket and stainless hardware to create liquid tight and corrosion resistant module.
- Utilized very low-power electronics and automatic ‘sleep mode’ to maximize battery life to allow for data collection and storage in the field for over 1 month.
