The combination of Renesas’ ZMOD4410 Total Volatile Organic Compounds (TVOC) and indoor air quality sensor, HS3003 temperature and humidity sensor, and RL78/G13 microcontroller (MCU) enables users to detect gases in the bathroom. Odor levels, temperature and humidity values can be monitored through a handy device by using a Bluetooth® module. The RL78/G13 MCU is suitable for industrial applications with high-performance peripheral functions, low power and an abundant lineup of MCUs. All the power on the sensor board is provided by the ISL9001A high-performance LDO and Li-ion battery. The ISL9301 is a high input voltage charger with a power path management charger for single-cell Li-ion/Polymer batteries.

System Benefits

  • Renesas’ MCU and Bluetooth® Low Energy (BLE) module control the system and wireless communication via BLE
  • Includes a high-performance/high-input voltage charger and low-input voltage/high-PSRR LDO for an integrated solution
  • The ZMOD4410 gas sensor module is a software configurable platform used for indoor air quality applications
