#### **Multi-Sensor Acquisition**
* **REQ-DAQ-001**
* **SR-DAQ-001**
The system shall support acquisition of data from multiple environmental sensor types simultaneously.
* **REQ-DAQ-002**
* **SR-DAQ-002**
The system shall provide a dedicated software driver abstraction for each supported sensor type.
* **REQ-DAQ-003**
* **SR-DAQ-003**
The system shall acquire sensor data only from sensors detected as present and enabled.
#### **High-Frequency Sampling & Filtering**
* **REQ-DAQ-004**
The system shall sample each enabled sensor multiple times within a single acquisition cycle.
* **SR-DAQ-004**
The system shall sample each enabled sensor multiple times within a single acquisition cycle (default: 10 samples).
* **REQ-DAQ-005**
* **SR-DAQ-005**
The system shall apply a local filtering mechanism to raw sensor samples to produce a single representative value.
* **REQ-DAQ-006**
The system shall allow configuration of sampling count and filtering parameters via system configuration data.
* **SR-DAQ-006**
The system shall allow configuration of sampling count and filtering parameters via system configuration data (Machine Constants).
* **SR-DAQ-010**
The system shall complete sensor acquisition cycle within a maximum of 100ms per sensor.
#### **Timestamped Data Generation**
* **REQ-DAQ-007**
* **SR-DAQ-007**
The system shall associate each processed sensor value with a timestamp.
* **REQ-DAQ-008**
* **SR-DAQ-008**
The system shall generate timestamps after completion of filtering.
* **REQ-DAQ-009**
* **SR-DAQ-009**
The system shall include sensor identifier, sensor type, value, unit, timestamp, and validity status in each sensor data record.
#### **Sensor State Management**
* **SR-DAQ-011**
The system shall track sensor operational states (INIT, WARMUP, STABLE, DEGRADED, FAILED).
* **SR-DAQ-012**
The system shall never publish raw sensor values without an accompanying validity flag indicating the current state.
* **SR-DAQ-013**
The system shall enforce sensor warmup durations (CO2: 30 seconds, Temperature: 5 seconds, others: sensor-specific).
