Synthetic Smart Home IoT Sensor Dataset — 1K Rows
Generated Dataset Summary
"Free CC0 synthetic dataset: 1,000 rows of indoor temperature, humidity, CO2, light and occupancy readings. Reproducible from its seed."
Generation Notes
Overview
Synthetic indoor environment sensor data for smart home IoT research. Generated using physics-based models including multi-harmonic Fourier temperature decomposition, CO₂ mass-balance ODEs, and time-dependent Markov occupancy chains.
This dataset contains 1,000 synthetic data points across 8 columns, generated with configuration: Setpoint: 22C.
Column Schema
| Column | Description |
|---|---|
Timestamp | ISO 8601 datetime |
Room | Categorical: Living_Room, Bedroom, Kitchen, Bathroom |
Temp_C | Indoor temperature (°C), range [15, 35] |
Humidity_Pct | Relative humidity (%), range [25, 85] |
CO2_ppm | CO₂ concentration (ppm), range [380, 2500] |
Light_Lux | Illuminance (lux), range [0, 1000] |
Occupancy | Number of occupants (0–8) |
HVAC_Status | Thermostat state: OFF, HEATING, COOLING |
Mathematical Models
All data points are generated from explicit, documented equations:
- Temperature:
Multi-harmonic Fourier: T(t) = T_set + A₁·sin(ω₁t + φ₁) + A₂·sin(2ω₁t + φ₂) + AR(1) noise - Humidity:
Cholesky-correlated with temperature (ρ = −0.65), room-specific modifiers - CO₂:
Mass-balance ODE: dC/dt = (n·G − Q·(C − C_out)) / V - Occupancy:
Time-dependent Markov chain with hourly transition probabilities - HVAC:
Three-state deadband thermostat (±1.5°C hysteresis) - Light:
Dual-source: sin²(solar) + occupancy-driven artificial
Suggested Use Cases
- HVAC optimization
- Occupancy detection/prediction
- Indoor air quality monitoring
- Anomaly detection in sensor networks
- Time-series forecasting benchmarks
Reproducibility
This dataset is fully reproducible. Generation seed: 423138832. Same seed + same parameters = identical output. Generated by IoTSyn v3.1.0.
