Process

How It Works

From device boot to live data on your phone in under a minute.

1
Power On
Device boots, initializes all 10 sensors, starts BLE advertising as "RaastkarIOT".
2
Connect
Open app or this website โ†’ scan โ†’ tap RaastkarIOT in the list.
3
Stream
ESP32 sends JSON sensor data every 5 seconds over BLE.
4
Analyze
App or website calculates carbon sequestration and builds history logs.
Science

Carbon Sequestration Formula

Our photosynthesis-based model calculates how much COโ‚‚ your plant absorbs daily using real sensor data.

๐ŸŒฟ
Leaf Area Index
Estimated from plant height via LiDAR โ€” taller plants capture more light.
โ˜€๏ธ
PAR from Light Sensor
Photosynthetically Active Radiation calculated from lux readings.
๐ŸŒก๏ธ
Temperature Factor
Optimal photosynthesis at 25ยฐC โ€” efficiency drops above/below.
// Carbon Calculation Formula
LAI = height ร— 0.02
PAR = lux ร— 0.0185
tempF = 1 - 0.02 ร— |temp - 25|
humF = humidity / 100
co2F = co2 / 400 (clamp 0.5โ€“2)
Carbon = PAR ร— LAI ร— tempF ร— humF ร— co2F ร— 0.5
