The combination of Renesas’ gas sensor, humidity sensor and RL78/G14 microcontroller (MCU), enables users to detect gases in a refrigerator. Odor levels, temperature and humidity values can be monitored through a handy device by using a Bluetooth® module. The RL78/G14 MCU 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
