Equipment and experimental environment

Equipment

SwitchBot MeterPro(CO2)

• Role in the experiment: household CO2 measurement
• Used in the experiment: used throughout AIEL-2026-0004, including the initial-alert, 30-minute repeat, silent-reset, and post-reset re-alert verification
• Current purchase source: Amazon.co.jp product page

This purchase link was recorded on 2026-08-23 as the purchase source for the CO2 sensor used in AIEL-2026-0004. The model identifiers, specifications, price, availability, and retailer-page state shown by Amazon were not independently re-verified, so those retailer details are not treated as experimental findings.

SwitchBot Hub Mini

• Model: W0202200
• Input: 5 V / 1 A
• Japanese radio certification: 210-130568
• Role in the experiment: data-collection hub used to make the MeterPro(CO2) measurements available through the SwitchBot cloud/OpenAPI path for collection into Google Sheets
• Used in the experiment: the same Hub Mini whose equipment information was recorded in AIEL-2026-0006 was also used in AIEL-2026-0004
• Current purchase source: Amazon.co.jp product page

In this experiment configuration, the Hub Mini was used so that MeterPro(CO2) measurements could be retrieved through the SwitchBot cloud and OpenAPI. The model, input rating, and Japanese radio-certification number are taken from the equipment record for the same physical Hub Mini used in AIEL-2026-0006.

The Hub Mini purchase link points to an Amazon.co.jp product page identified from current sales information for the W0202200 product family and is provided only as a purchasing reference. Identity with the experiment-used unit in production date, internal components, firmware, and current retailer state has not been established, so the purchase link is not treated as Experiment Evidence.

Experimental environment

SwitchBot OpenAPI v1.1

• Type: SwitchBot cloud API
• Role in the experiment: retrieval of CO2 values relayed to the cloud through the Hub Mini
• Purchase: not required

Google Apps Script

• Role in the experiment: roughly five-minute collection trigger, CO2 state evaluation, and LINE push invocation
• Purchase: not required

Google Sheets

• Role in the experiment: private household-environment measurement logging
• Purchase: not required

LINE Messaging API / LINE Official Account

• Role in the experiment: ventilation notification to the private family group
• Purchase: not required

Cloudflare Worker

• Role in the experiment: temporary webhook receiver used only while obtaining the group ID
• Purchase: not required
• Note: the Worker was deleted and webhook delivery disabled after the group ID was obtained, so it is not used in the current production alert path.

How purchase information is used

Purchase links are supporting information intended to make equipment used in the experiment easier to identify. A currently purchasable product is not assumed to match the experiment-used equipment in production date, internal components, firmware, connected-system configuration, or behavior. Purchase information is not treated as evidence that strengthens experimental findings or Evidence States.
