The combination of Renesas’ gas sensor, humidity sensor, and RL78/G14 MCU, enables users to detect gases in the refrigerator. Odor levels, temperature and humidity values can be monitored through a handy device by using a Bluetooth® module. The RL78/G14 microcontroller is suitable for industrial applications with high performance peripheral functions. All the power on the sensor board is provided by the ISL80101A high performance LDO.

System Benefits

  • Easily detect gases emitted from spoiling food
  • The ZMOD4450 gas sensor module is a software configurable platform designed for detecting gases associated with food ripening or rotting and is targeted for use in refrigeration air quality (RAQ) applications
