Web3 public sensors map
Welcome to the decentralized opensource sensors map which operates with the sole intent of serving the free will of individuals , without any beneficiaries. It offers two distinct layers of decentralization at your choise: peer-to-peer connectivity for direct access to sensor data, and the federative concept for accumulating sensor data and displaying measurement history.

Altruist & sensors.social
You track your pulse and sleep quality. Now learn about your living environment.
Two-module environment monitoring kit for indoors and outdoors — for those who care about health.
The Challenge: Measure Your Living Environment
You track your pulse, HRV, sleep phases. To achieve the best recovery results — you need to account for sleep conditions and the environment you live in.
Indoors
- CO2 — the main indicator of stuffiness and sleep quality
- Temperature and humidity — comfort and mold prevention
Outdoors
- Dust PM2.5/PM10 — know when it is safe to ventilate
- Noise — explain awakenings and assess your neighborhood
- Temperature and humidity — the full picture outside your window
This lets you make data-driven decisions: when to open windows, when to turn on the purifier, how to improve sleep.
Solution: Altruist Bundle
Two modules — one picture of your living environment:
Urban (balcony / roof)
- Dust PM2.5 / PM10 (SDS011)
- Temperature and humidity
- Noise level
- Atmospheric pressure
"What is outside the window right now?"
Insight (bedroom / living room)
- CO2
- Temperature
- Humidity
- E-ink display 4.2" + SD card
"What am I breathing at home?"
Key feature — indoor/outdoor comparison: when to ventilate and when to close the windows.

Who Needs Altruist
Health tracking?
Wear a WHOOP, Oura, or sleep tracker — Altruist completes the picture. CO2 in the bedroom affects sleep depth. Outdoor noise explains awakenings. Dust triggers allergies and asthma.
Asthma and allergies
PM2.5 < 30 µg/m³ in the bedroom. Rising outdoor dust → signal to close windows and turn on the purifier.
Children
CO2 and dust in the nursery. Mold prevention through humidity control.
Real estate
Quick environment assessment when moving — data you'll discover over years. Charts boost the appeal of rental housing.
Automation
Control air purifiers and air conditioners using indoor/outdoor sensor data.
Civic monitoring
Dust storms, industrial emissions, noise background. Data is available to everyone via the open map sensors.social.
7 Years of Altruism
| Year | Event |
|---|---|
| 2017–2018 | First R&D — air quality measurement at playgrounds in an industrial city. Professional certified sensors, IoT cloud transmission. |
| 2018 | Trust problem: society rejects citizen monitoring data. Pivot to the Luftdaten/sensors.community model from Stuttgart — affordable DIY kits instead of expensive stations. |
| 2019 | Three R&D projects: dozens of sensors on city billboards, a solar water drone for water quality analysis, drones over landfills. Recognition at IoT World Congress in Barcelona. |
| 2021 | Launch of sensors.social prototype, showcase at UN COP25 platform. Federated sensor network architecture, all code on GitHub. |
| 2022–2025 | Custom hardware development: ~7 PCB iterations, manufacturing in China, assembly, field tests. By mid-2025 — the two-module Altruist is ready for sale. |
| 2026 | Indiegogo, then Amazon and regional distributors. EU/US certification. |
Dozens of software releases over 4 years to build a user sensor network without corporate clouds. 120+ sensors on 4 continents.
