Plugfield

What Plugfield does

Plugfield Tecnologia em Agronegócios S.A. is a Brazilian manufacturer of online weather stations and specialized environmental sensors, headquartered in Curitiba, Paraná. The company was founded in 2018 and operates as a wholly-owned subsidiary of the Pumatronix Group. Its product portfolio centers on the Plugstation line of compact, solar-powered automatic weather stations (current generation WS22, plus Sônica and Pluviométrica variants, with WS18, WS21 as prior generations) and a modular Plugsensor family covering soil moisture, leaf wetness, pH/ORP, CO2/NH3, ultrasonic and piezometric liquid level, visibility, inclination, and solar radiation. Data is transmitted via WiFi, 2G/3G/4G, satellite, or LoRaWAN to a cloud-based web portal and Android/iOS mobile app, with PlugAPI exposing data to third-party systems and a PlugAPI Pro tier monetizing higher-volume enterprise access.

The company's primary go-to-market is direct enterprise sales supplemented by a channel partner program of distributors and integrators across Brazil. The product is positioned for three vertical markets: agribusiness (the dominant segment, with cooperatives such as Cooxupé, Coopercitrus, and Cocari as named customers), smart cities (river-level and urban flood monitoring), and highways (visibility and weather-driven accident prevention, with NTCIP support meeting ANTT resolution nº 3,323). The revenue model is predominantly one-time hardware sales with a modest recurring software layer, and Plugfield explicitly states no subscription or monthly fee is required for standard station operation.

Plugfield is certified by Anatel (Brazilian telecommunications regulator) and ISO 9001 (Bureau Veritas), holds the Selo Indústria Brasileira, and is a partner of INMET, Brazil's national meteorological institute. The company is private, has no disclosed funding rounds, and is part of the broader Pumatronix technology group that provides corporate, manufacturing, and distribution infrastructure.

Revenue model

1. Hardware Sales (Weather Stations and Sensors): Plugfield generates revenue primarily through the sale of its Plugstation weather stations (WS18, WS21, WS22 models) and Plugsensor add-on sensors (Solo, Foliar, CO2, pH, Inclinometer, Visibility, Radiation, Level). The company explicitly states no subscription or monthly fee is required. The WS22 model supports three additional sensor ports, allowing customers to customize their monitoring setup.
2. API and Software Access (PlugAPI Pro): Plugfield offers the PlugAPI Pro service for customers requiring more than 5,000 API accesses per month per weather station. This provides a tiered, usage-based revenue stream for higher-volume enterprise customers.
