Altruist

With the **Altruist** Outdoor Sensor, you become a force in decentralized environmental monitoring. Capture noise, dust, and temperature data—encrypted, mapped, and shared across a distributed network.

Experience the power of true DePIN (Decentralized Physical Infrastructure Network) — a revolutionary technological movement brought to life and thriving for years on our [decentralized sensor map](https://sensors.social/).
