Find answers about the Water Drop MARAI sensor, subscription model, installation and environmental compliance.
The Water Drop MARAI is an IoT water quality monitoring sensor, developed by Chemical Inovação after more than 10 years of R&D and several registered intellectual properties.
It collects physical-chemical data in real time and transmits via IoT to the MARAI App, accessible from any smartphone or computer - no laboratory or manual sample collection required. The app also performs an integrated site assessment, factoring in surrounding environmental variables to contextualize results and support environmental decision-making.

The Water Drop MARAI sensor continuously monitors the standard parameters:
The system is expandable through a plan upgrade or contract renewal to also include.
No. The Water Drop MARAI Station can be powered by solar energy with an integrated backup battery - ensuring 24/7 operation even in remote locations, with no electrical infrastructure or civil works required.
This enables deployment in rivers, lakes, reservoirs, WWTPs, WTPs and water tanks without additional infrastructure cost.
Preventive maintenance and periodic calibration are included in the subscription plan. Our technical team performs scheduled site visits according to each sector's protocol.
Customers don't need to worry about spare parts, calibration or logistics - everything is managed by Chemical Inovação.
In the HAAS (Hardware as a Service) model, the client pays a monthly subscription and receives the full monitoring service - without purchasing any equipment.
Included in the subscription:
No. Under the HAAS model, all hardware (sensor, station, solar panels, IoT connectivity) belongs to Chemical Inovação and is provided to the customer through the subscription.
This eliminates high upfront investment in equipment and facilitates onboarding - especially for companies that need immediate compliance with environmental regulations.
Technical reports are generated and delivered within 48 hours by e-mail, in PDF format signed by a qualified technical officer.
Raw data is also available in real time via the MARAI App, with complete history, charts and export. Automatic alerts are sent by e-mail or push notification when any parameter exceeds the configured threshold.
Subscription plans have a minimum commitment as per contract, which may vary by case.
Upon cancellation, our team retrieves the equipment from the site.
Installation of the Water Drop MARAI Station typically takes 1 to 2 business days, depending on the site and the number of monitoring points.
No civil works or electrical installations are required - the system is autonomous and uses its own mounting structure adapted to the environment (post, reservoir edge, riverbank, etc.).
Yes. Connectivity is established via cellular network (4G/2G) or LoRaWAN, depending on local coverage. The sensor stores data locally if the signal is lost and syncs automatically when the connection is re-established.
For locations with very limited coverage, satellite solutions can be evaluated upon request.
Yes. The Chemical Inovação solution was designed to meet the requirements of CONAMA Resolution 430/2011 (effluent discharge standards) and supports compliance with ISO 14001 (environmental management systems).
The technical reports issued by Chemical Inovação are valid for submission to environmental regulatory agencies.
The MARAI App is Chemical Inovação's digital platform, available on smartphone (iOS and Android) or via web browser. It shows:
Access is granted after subscription activation, with individual login and password.
Yes. The MARAI App supports multiple monitoring points under a single account. Each station is identified by name and location, and all data is centralized in the same dashboard.
Companies with facilities in different locations or municipalities can monitor all points simultaneously, with individual alerts per station.
Chemical Inovação serves companies and organizations across the following sectors:
Yes. The Water Drop MARAI Station is designed for deployment in open water bodies, including rivers, lakes, dams, reservoirs and irrigation canals.
The structure is adapted to the environment (floating, bank-mounted or bottom-anchored, as needed), and solar operation ensures autonomy even in hard-to-reach locations.
The process is simple and fast:
Yes. We are headquartered in Curitiba - PR with a branch in Manaus - AM, serving clients across the entire country.
For regions far from our operation centers, we evaluate local technical partners to ensure adequate maintenance response times.
