The TSM400-1-CP is a multi-parameter 1-Wire sensor designed for long-term indoor CO₂ and atmospheric pressure monitoring. Housed in a slim enclosure for flush-mounting in standard Ø68 mm wall boxes, it uses NDIR technology for accurate CO₂ measurement with both automatic and manual fresh-air calibration options. Pressure readings are derived from a factory-calibrated sensor requiring no further adjustment. An LED indicator shows communication status, and firmware updates can be performed via the 1-Wire interface. Powered directly through the bus, the TSM400-1-CP delivers stable, high-precision performance for applications such as office air-quality management, pollution monitoring, and intelligent ventilation control.
