A Greenhouse Climate Node: Light, Carbon Dioxide, Humidity, and Ventilation Control in One Instrument

Year: 2026

Type: article

Abstract: Design of a greenhouse climate node combining PAR light, dual-wavelength NDIR carbon dioxide (5.0 cm path), and capacitive humidity/temperature sensing with a hysteretic vent/fan relay control law. Performance budget computed from Beer-Lambert, air-exchange, buoyancy-flow, and daily-light-integral arithmetic. SIMULATED, NOT MEASURED: no hardware was built or tested.
