MEMS Odor Smell Gas Detection Sensor
Overview
The Fermion MEMS Odor Smell Gas Detection Sensor is a compact, high-accuracy micro-electromechanical systems (MEMS) based sensor designed to detect and identify various types of gases, odors, and volatile organic compounds (VOCs) in the air. This sensor is ideal for integration into IoT devices, air quality monitoring systems, and smart home appliances.
Functionality
The Fermion sensor utilizes a proprietary MEMS technology to detect changes in the ambient air, leveraging the principles of thermal conductivity and heat transfer. The sensor consists of a micro-hotplate and a sensitive thermistor, which work in tandem to detect minute variations in the thermal conductivity of the surrounding air. This allows the sensor to identify the presence of specific gases, odors, and VOCs, including |
Organic compounds (VOCs)
Inorganic gases (e.g., CO, NOx, SO2)
Odorous gases (e.g., H2S, NH3)
Airborne particles and pollutants
The sensor's micro-hotplate is heated to a specific temperature, causing the surrounding air to expand and contract. As the air molecules interact with the hotplate, the thermistor measures the resulting changes in thermal conductivity. The sensor's onboard circuitry processes these measurements to produce a digital signal, which is then transmitted to a microcontroller or other processing unit for interpretation.
Key Features
- High Sensitivity and Accuracy: The Fermion sensor boasts high sensitivity and accuracy, enabling detection of gas concentrations as low as 1 ppb (parts per billion).
- Multi-Gas Detection: The sensor can detect and distinguish between various gases, odors, and VOCs, making it suitable for a wide range of applications.
- Low Power Consumption: The sensor operates at a low voltage (3.3V) and current (10mA), minimizing power consumption and enabling battery-powered or energy-harvesting applications.
- Compact Size: The Fermion sensor measures only 3mm x 3mm x 0.9mm, making it ideal for integration into compact IoT devices and wearables.
- Fast Response Time: The sensor responds rapidly to changes in the air, with a response time of <1 second.
- High Temperature Range: The sensor operates across a wide temperature range (-20C to 50C), allowing it to function reliably in various environmental conditions.
- Digital Output: The sensor provides a digital output, simplifying integration with microcontrollers, processors, and other digital systems.
- RoHS and CE Compliant: The Fermion sensor meets RoHS and CE standards, ensuring compliance with European Union regulations.
