Touchless Toilet with Biosensor

This solution shows a toilet design using the DA14531 SmartBond TINY™ module, the smallest, most power-efficient Bluetooth® Low Energy (LE) solution available. This Bluetooth LE module targets broad market usage and is certified across regions providing significant savings in development cost and time-to-market. Additionally, multiple sensors are used to realize automatic cover opening, humidity and temperature measurement, and to monitor health.

System Benefits

  • Bluetooth LE and MCU: The Bluetooth LE module comes with an integrated antenna and easy-to-use software, making Bluetooth Low Energy development easier than ever before.
  • Low cost 48MHz Arm® Cortex®-M23 core MCU with enhanced capacitive touch sensing unit 2 (CTSU2).
  • Strong power source: High-performance and high-output ability power device, AC/DC + Buck are enough to cover all power supply needs.
  • More intelligent design keeps users healthier.

Target Applications

  • Smart toilets
  • Smart environment monitors
