ZMOD4450 Overview
The ZMOD4450 Gas Sensor Module is designed for detecting gases associated with food ripening or rotting and is targeted for use in refrigeration air quality (RAQ) applications; for example, food storage and shipping. The sensor is a 12-pin LGA assembly (3.0 3.0 0.7 mm) that consists of a gas sense element and a CMOS signal conditioning IC.
ZMOD4450 Key Features
- Measurement of gases associated with food ripening and storage: ethylene, amines, volatile sulfur pounds
- Configurable methods of operation based on application and use case
- Heater driver and regulation loop for constant heater voltage or constant heater resistance
- Internal auto-pensated temperature sensor; not stress sensitive
- I2C interface: up to 400kHz
- Configurable alarm/interrupt output with static and adaptive
- Adjustable ADC resolution for optimal speed versus
- Built-in nonvolatile memory (NVM) for user data
- Low average power consumption in the mW range
- Firmware upgradable platform for application optimizations
