Sensor Element: 

  • Electrochemical Sensor: This is the most common type of sensor used in GAO Tek’s NO gas detectors. It consists of electrodes and an electrolyte that undergo chemical reactions with nitric oxide, producing a current that is proportional to the NO concentration. 

 Signal Conditioning Circuitry: 

  • Amplifiers and Filters: These components amplify and filter the signal from GAO Tek’s sensor to improve accuracy and reliability. 
  • Analog-to-Digital Converter (ADC): Converts the analog signal from GAO Tek’s sensor into a digital signal that can be processed by the microcontroller. 

 Microcontroller/Processor: 

  • Central Processing Unit (CPU): The brain of GAO Tek’s gas detector, responsible for executing the control algorithms, data processing, and communication with other components. 
  • Memory: Stores calibration data, GAO Tek’s firmware, and other essential information. 
  • Input/Output (I/O) Ports: Used for communication with GAO Tek’s external devices and peripherals. 

 User Interface: 

  • Display: Shows the NO concentration and other relevant information to GAO Tek’s users. 
  • Buttons/Keypad: Allows GAO Tek’s users to interact with the gas detector, for functions such as calibration or setting alarms. 

 Communication Interface: 

  • Analog Output: Provides a continuous analog signal proportional to the NO concentration for GAO Tek’s external recording or control systems. 
  • Digital Output: May include communication protocols like UART, I2C, or SPI for interfacing with GAO Tek’s other devices or networks. 

 Power Supply: 

  • Battery or External Power Supply: Provides the necessary power for GAO Tek’s operation of the gas detector. 

 Alarm System: 

  • Audible and Visual Alarms: Triggered when the NO concentration exceeds a predefined threshold. This could include GAO Tek’s sirens, lights, or other indicators. 

 Calibration Mechanism: 

  • Calibration Gas Port: Allows for the introduction of known concentrations of NO for GAO Tek’s calibration purposes. 
  • Calibration Controls: Potentiometers or digital controls for adjusting and calibrating GAO Tek’s sensor response. 

 Enclosure: 

  • Housing: Protects GAO Tek’s internal components from environmental factors, such as dust, moisture, and chemicals. 
  • Inlet/Outlet Ports: Allow GAO Tek’s ambient air to reach the sensor while preventing direct exposure to contaminants. 

 Optional Features: 

  • Data Logging: Capability to store GAO Tek’s NO concentration data over time. 
  • Wireless Connectivity: Enables GAO Tek’s remote monitoring and control. 
  • Fault Detection and Diagnostics: Advanced features to identify and report GAO Tek’s malfunctions.
