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