Accreditation, Calibration, and Building-Standard Statements

Effective June 1, 2026 · Version 1.0 · Operational reference; the Terms of Service control.

This page is the device-level accreditation status reference identified at §7.1 of the Terms of Service for the Terrestream Indoor Air Quality Sensor (the “ Device ”), together with the component-level building-standard statements published by the component manufacturers and reproduced here under §7.1. The Terms of Service control; this page is operational reference material only.

⚠️ Convenience-only reproduction; no warranty; no attestation

The component-manufacturer statements reproduced on this page and the PDFs hosted or linked from this page are provided for User convenience only. The component-manufacturer statements are statements of the component manufacturer, made on its public product documentation, and are reproduced here without modification. Aerodyne does not attest to, endorse, or independently verify any statement contained in a component-manufacturer publication, and does not independently test, certify, audit, or verify the component manufacturer’s published statements about its components. The User may independently verify any quoted statement against the manufacturer’s then-current public documentation at the cited URL. The non-reliance, no-extrinsic-representation, and limitation-of-liability provisions of the Terms of Service (including, without limitation, §7, §9, and §15) apply to this page in full.

Device-level accreditation

The Device holds no device-level accreditation at this time. RESET® Air, the WELL Building Standard™, LEED, Fitwel, BREEAM, and similar programs accredit complete indoor-air-quality monitors as systems, not the component sensors used inside them. Device-level accreditation depends on the Device’s data pipeline, calibration program, placement, signaling, audit posture, and other factors in addition to component performance. Component-manufacturer statements quoted in §7.1 and reproduced on this page do not constitute device-level accreditation of the Device.

Any reference in Terrestream’s marketing, documentation, Mobile App, Web Dashboard, or Services to a building-performance standard for which the Device has not been accredited at the device level is informational alignment only.

Component-level building-standard statements

The following statements are made by the component manufacturer on its public product documentation and are reproduced here for User reference only. Each statement is verifiable at the source URL. The component identifications and BOM-by-configuration mapping for the Device are at /legal/sensor-compliance.

Sensirion SEN66 (installed in every Device)

Sensirion publishes: “Applications requiring compliance with IAQ standards – such as RESET®, WELL Building Standard™ and California Title 24 Building Energy Efficiency Standards – are well served by the SEN66.” Source: Sensirion AG, SEN66 product page, sensirion.com/products/catalog/SEN66. Sensirion further publishes the SEN6x Datasheet and the SEN6x Sensor Specification Statement (Sensirion, January 2026), available at sensirion.com/products/catalog/SEN66 under “Downloads.”

  • Local copy of the SEN6x Datasheet (Sensirion, 12/2025) — PDF.
  • Local copy of the SEN6x Sensor Specification Statement (Sensirion, 01/2026) — PDF.

Sensirion SCD43 (installed only in product configurations identified at /legal/sensor-compliance)

Where the SCD43 is installed, Sensirion publishes that the SCD43 offers “compatibility with the most stringent building standards, including ANSI/ASHRAE 62.1-2022 Draft Addendum d, California Title 24, RESET® grade B and WELL Building Standard™ (WELL v2).” Source: Sensirion AG, SCD43 product page, sensirion.com/products/catalog/SCD43. Sensirion further publishes the SCD4x Datasheet, the SCD4x Design-in Guide, and the SCD4x Testing Guide, available at sensirion.com/products/catalog/SCD43 under “Downloads.”

  • Local copy of the SCD4x Datasheet (Sensirion, 04/2025) — PDF.
  • Local copy of the SCD4x Design-in Guide (Sensirion, 01/2021) — PDF.
  • Local copy of the SCD4x Testing Guide (Sensirion) — PDF.

Bosch BMP390L (installed in every Device)

Bosch Sensortec publishes the BMP390 / BMP390L Datasheet at bosch-sensortec.com/products/environmental-sensors/pressure-sensors/bmp390. Barometric pressure is not a parameter governed by RESET® Air, the WELL Building Standard™, ANSI/ASHRAE 62.1, California Title 24, or LEED Indoor Environmental Quality credits; Bosch publishes no indoor-air-quality building-standard compatibility statement for the BMP390L, and none is reproduced here.

Texas Instruments OPT3001 (installed in every Device)

Texas Instruments publishes the OPT3001 Ambient Light Sensor Datasheet at ti.com/product/OPT3001. Ambient illuminance is not a parameter governed by RESET® Air, the WELL Building Standard™, ANSI/ASHRAE 62.1, California Title 24, or LEED Indoor Environmental Quality credits; Texas Instruments publishes no indoor-air-quality building-standard compatibility statement for the OPT3001, and none is reproduced here.

Component-manufacturer calibration certifications

The component manufacturers publish calibration-certification documents identifying the calibration methodology and traceability references for the components incorporated in the Device. Aerodyne does not perform device-level calibration accredited to ISO/IEC 17025 or analogous laboratory-accreditation standards at this time; the documents below are the component-manufacturer’s publications and are reproduced for User reference only.

What Terrestream represents and what it does not

Per §7.1 of the Terms of Service, Terrestream’s representations concerning the Device’s accuracy are limited to the device-level specifications published in the Device documentation and to the drift, calibration, and user-responsibility provisions of §6. Terrestream makes no independent representation that any component, as integrated into the Device or under real-world deployment conditions, retains or replicates the characteristics described by the component manufacturer in the publications reproduced on this page.

Updates

This page is updated when (a) the Device acquires a device-level accreditation, (b) a component is added to or removed from the Device bill-of-materials at /legal/sensor-compliance, or (c) a component manufacturer publishes a materially revised building-standard statement or calibration certification. Prior versions are preserved at /legal/archive.
