Foundation for Environmental Monitoring
Caddisfly - A field test kit for drinking water and soil based on a smartphone

About

Foundation for Environmental Monitoring (FFEM), is a nonprofit (Section 8) company based in Bangalore, India.

We create products that are Open Source, Inexpensive, and Designed for field use. Our products are usually integrated with apps that post test results to online databases. We encourage results being posted as Open Data.

Elements of our work begain 2012 as Ternup Research Labs. In 2014, our team merged with Akvo. FFEM was set up as a spinoff in June 2017. This post explains the context and future directions.

FFEM Caddisfly: Water and Soil Test Kits

Water tests

Tests are for drinking water. These tests (except for Electrical Conductivity) are colorimetric tests that use a smaprtphone camera and flash to detect the contaminant. The electrical conductivity test works by attaching a probe to the USB port of a smartphone.

  • Fluoride
  • Residual Chlorine
  • pH
  • Nitrate
  • Phosphate
  • Chromium
  • Arsenic (Product development and validation underway)
  • Coliforms / Fecal Coliforms (Product development underway)
  • Electrical Conductivity (Preproduction)

Soil tests

Soil NPK and pH are strip tests / colorimetric test. Soil EC and Soil Moisture work by attaching probes to the USB port of a smartphone.

  • Soil NPK - Nitrogen, Phosphorous, and Potassium (Beta)
  • Soil pH (Beta)
  • Soil EC (Preproduction)
  • Soil Moisture (Preproduction)
