ESP-CSI uses Wi-Fi Channel State Information (CSI) on all ESP32 chips to sense breathing, chewing, walking, or other movements without contact or extra hardware. You get rich data like signal phase and amplitude for smart monitoring, activity detection, positioning, and AI apps, with easy OTA upgrades, BLE help, and examples for quick starts like radar or cloud uploads—saving costs while boosting your IoT projects' accuracy and reliability.

Not all carbon is the same - some heats the planet, others help #cool it.
1/. Black Carbon – Soot from incomplete combustion; strong warming effect
2/. Brown Carbon – Biomass smoke aerosols; absorbs sunlight

4/. Green Carbon – Stored in forests, soils, and vegetation
5/. Red Carbon – Biological matter on snow & ice; accelerates melting
6/. Grey Carbon – Fossil fuel–based industrial emissions
