Touchless Toilet with Biosensor

Renesas’ reference design for a touchless toilet with biosensor has an intelligent design that keeps users healthier

Image of Renesas’ Touchless Toilet with BiosensorRenesas’ winning combination reference design for a touchless toilet with biosensor uses the DA14531 SmartBond TINY™ module, a small efficient Bluetooth® Low Energy (LE) solution. This Bluetooth LE module targets broad market usage and provides significant savings in development cost and time-to-market. Additionally, multiple sensors are used to realize automatic cover openings, humidity and temperature measurements, and monitor health.

Features
  • Bluetooth LE and microcontroller (MCU): the Bluetooth LE module comes with an integrated antenna and easy-to-use software
  • Low-cost 48 MHz 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 plus buck are enough to cover all of the power supply
  • Intelligent design keeps users healthier
  • iW1760B AC/DC conversion
    • 45 W AC/DC off-line controller for power adapters that offer lower output ripple
  • OB1203 biosensor
    • Heart rate, blood oxygen concentration, pulse oximetry, proximity, light, and color sensor
  • ISL85003 buck regulator
    • Highly efficient 3 A synchronous buck regulator
  • ISL29501 proximity sensor
    • Time-of-flight (ToF) signal processing IC
  • DA14531MOD connectivity
    • SmartBond TINY module, small and low power Bluetooth 5.1 system on chip (SoC)
    • Brings DA14531 SoC advantages to an integrated module
  • HS3003 humidity and temperature sensor
    • High-performance relative humidity and temperature sensor
  • RA2E1 MCU
    • 48 MHz Arm Cortex-M23 entry-level general purpose MCU
  • PS2911-1 photocoupler
    • High CTR, 4-pin ultra-small-package flat-lead photocoupler
  • SLG46855 programmable mixed-signal devices
    • GreenPAK™ programmable mixed-signal matrix
  • SLG47105 programmable mixed-signal devices
    • Mixed-signal logic and high voltage H-bridge functionality in a tiny 2 mm x 3 mm QFN package
Applications
