Onchain Temperature

1. Bluetooth sensor

   A sensor in my garden broadcasts readings every 4 seconds.

2. Raspberry Pi

   Receives the broadcasts and stores a reading once a minute.

3. Net on Base

   Every four hours, the Pi sends the latest reading onchain via Net Protocol.

Data display: This page reads the temperature data directly from Base. Switch between the chart and a table of readings above, and use the dropdowns to choose a date range and how the chart draws it.

Technical details: All readings are stored permanently onchain with timestamps, making this a decentralised and tamper-proof temperature log. Readings are sent from address 0x418617b377e742ea2924673dc5470a6da89db94e.
