Sensor calibration data, reference-method comparisons, and digital MRV documentation for Virridy's Lume water-quality sensing platform.
Controlled test of the VL53L1X distance channel on 50059 and 500214 across cap state and medium. Conditions, timings and raw readings.
How a reading travels from the device through Notehub, Pumphaus, the inventory database, the baseline store and the E. coli model to a customer dashboard — plus how to reach the validation grabs, the invariants that must hold at every join, and the audit that checks them.
Paired calibration against two EPA-approved reference methods — Colilert (IDEXX, MPN) and membrane filtration (CFU) — with lab, field, and combined models.
→Calibration against the Aquagenx CBT used in international monitoring programmes, with field data from Rwanda and Kenya deployments.
→Time-of-flight sensor calibration to Nephelometric Turbidity Units using laboratory and field reference standards.
→Tryptophan serial-dilution bench test characterizing the TLF fluorescence channel against known concentration, read live across 14 sensors.
→Flowing vs. still water classification for piped systems, supporting SDWS 23 (water volume) monitoring.
→Lume sensor performance in wastewater matrices — high-turbidity, high-fluorescence environments beyond typical drinking-water ranges.
→Digital Measurement, Reporting & Verification for the Amazi Meza Rwanda water treatment carbon credit programme. Includes the implementation plan, pilot report with FAR resolution evidence, and VVB findings.
