The FieldKit Platform
Environmental Monitoring Made Accessible
FieldKit is a modular environmental sensing platform combining rugged hardware, precise sensors, and user-friendly software to democratize high-quality environmental data collection. The system features an open-architecture logger that connects to custom FieldKit sensors, supported by a mobile app for field use and a web portal for data visualization and collaboration. This cohesive platform lowers technical and financial barriers to field monitoring, empowering conservation groups, educators, researchers, and communities to collect and act on trustworthy environmental data.

Data Logger
Modular FieldKit hardware allows you to gather high-quality data across various modalities for your project and connect to our data conversation portal through an easy-to-use mobile app. This enables you to deploy an array of sensing systems to capture more data at lower cost, creating greater spatial diversity, more measurements, and enhanced redundancy. It’s a system you can trust anywhere, gathering data you can be confident in.
Data capture frequency is customizable via the mobile app and can be set as frequently as every minute. Integrated GPS provides location and timestamp data, synchronized across all four sensor module bays.

Mobile App
Connect directly to your station via our mobile app and reduce the need for finicky physical data retrieval. Our app simplifies configuring and calibrating your station, as well as downloading and viewing data effortlessly from your mobile device. And, with your data backed up to your mobile device, you don’t need to worry about dropping that microSD card in the field.
- Handles sensor calibration, GPS tagging, local data downloads (to .csv), and uploads to the FieldKit Data Portal
- Provides visual feedback and status updates in the field alongside contextual metadata
- Users can submit logs (from data logger) manually from app
- Designed for non-technical users and rugged, intermittent connectivity contexts
- Benefits: Simplifies deployment and reduces calibration errors; eliminates need for laptops or proprietary tools in the field
Data Portal
Station data comes to life within the FieldKit portal. Connecting to the portal lets you quickly and easily visualize station data, discover trends and patterns, add comments, and share your findings with anyone. If desired, collaborators and the public can comment on trends and ask questions. Or, you can keep your data private—no matter what, your data will always be yours and free to access and manipulate at no cost.
- Upload and visualize field data from FieldKit stations; create projects and share datasets
- Compare data from two different time periods or multiple sensors during the same time period on a single chart
- Enables centralized management of stations and their data, tied to collaborative projects and user accounts
- Supports data cleaning, charting, and download in open formats
- Enables team-based workflows and open science collaboration
- Each data view becomes its own unique URL, available for sharing or using as a reference
- Benefits: Turns raw field data into actionable insights; supports transparency, repeatability, and knowledge-sharing
Sensors
Our team develops high-quality, low-cost sensors that rival traditional tools, making broader spatial coverage and community-based maintenance feasible. The result is not only richer data, but a more equitable scientific project. Research-grade, rugged sensing at a fraction of the cost of traditional tools allows for dense deployments in highly varied terrain and environmental conditions.
All our sensors are modular and can be deployed on the data logger in whatever combination best fits your sensing needs.
- Mix and match water chemistry (pH, DO, EC, temp), distance, and weather sensors
- Designed for modularity, affordability, and open-spec calibration routines
- Seamlessly integrate with the logger with redundant storage to keep your data safe
