# ecoTrace biogas-sensor pilot: installation and feasibility, Kiambu County, Kenya
Figures and figure-generating code for the installation and social-science short
communication: a feasibility assessment of low-cost, manufacturer-independent
digital MRV for household biogas, from the ~6-month, 20-household Kiambu pilot.
The paper argues that low-cost independent monitoring can capture operational
status and use rhythms but is not yet a turnkey route to calibration-free
absolute quantification.
The manuscript prose lives in the authors' private paper repository; only the
code and the final figures are here. The survey analysis, the cohort use-rhythm
analysis and the feasibility check against literature production envelopes
belong to the companion technical paper, *ecoTrace biogas-sensor pilot, Kiambu
County, Kenya: sensor, calibration and CFD* — cited here by name only, not by
repository path. This repository's own `fig_diurnal` is narrower: one
household's normalised, shape-only use rhythm, not the cohort analysis.

## The figures
- **`fig_coverage`** (Figure 1): daily telemetry-completeness heatmap, one row
per device serial, de-identified. Reads raw Parquet from the data repository
and re-derives what it needs.
- **`fig_diurnal`** (Figure 2): one household's normalised daily use rhythm.
Each day is normalised to 100%, so the figure is shape-only and carries no
absolute volumes. Reads the data repository's derived CSVs.
- **`installation_sites_22.png`**: map of the 22 installation sites in Kiambu
County. Produced manually, not by code in this repository: household GPS is
not part of the published dataset, so the map c …
