Abstract
"Synthetic Smart Home dataset with 100 data points. 8 columns. Config: Setpoint: 26.5C. CC0 licensed."
Description
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.
100 data points, 8 columns. Config: Setpoint: 26.5C.
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
- Temperature:
Multi-harmonic Fourier: T(t) = T_set + A₁·sin(ω₁t + φ₁) + A₂·sin(2ω₁t + φ₂) + AR(1) - Humidity:
Cholesky-correlated with temperature (ρ = −0.65) - CO₂:
Mass-balance ODE: dC/dt = (n·G − Q·(C − C_out)) / V - Occupancy:
Time-dependent Markov chain - HVAC:
Three-state deadband thermostat (±1.5°C hysteresis)
Use Cases
- HVAC optimization
- Occupancy detection
- Indoor air quality monitoring
- Anomaly detection
- Time-series forecasting
Reproducibility
Seed: 100570885. Same seed + parameters = identical output. IoTSyn v3.1.
