Temperature sensor for an enclosure

Edit

Watch the air or a wall inside a box so a fan, heater, or logger has a trustworthy number. Prefer a digital sensor with a defined accuracy and a package you can keep off a hot regulator.

Starting part numbers

From the local map. These are examples, not the live result list.

  • MCP9808-E/MS

    Microchip

    I2C, easy to bring up, widely stocked.

  • TMP102

    Texas Instruments

    Small, cheap enough for a spare channel.

  • TMP117

    Texas Instruments

    High-accuracy digital; good when the box is the product.

Live parts

On-demand from Nexar and/or DigiKey. Nothing here is a catalog Byuse owns. Specs appear only if the API returned them.

No distributor key is set. Browsing still works. To see live parts, add one of these pairs to .env.local and restart the dev server:

  • NEXAR_CLIENT_ID
  • NEXAR_CLIENT_SECRET
  • DIGIKEY_CLIENT_ID
  • DIGIKEY_CLIENT_SECRET

Nexar needs NEXAR_CLIENT_ID and NEXAR_CLIENT_SECRET. DigiKey needs DIGIKEY_CLIENT_ID and DIGIKEY_CLIENT_SECRET.
