PROBLEM TO SOLVE / TASK
Using a rain gauge can present several challenges and potential sources of error, including:
If not checked regularly, water in the gauge can evaporate, leading to lower recorded values.
Human error can occur when reading the measurement, especially with traditional gauges that require manual recording.
During heavy rain events, some gauges might overflow or fail to capture the total amount of rainfall accurately.
Automated gauges need a consistent power supply or regular battery changes to function correctly.
Rainfall can vary significantly over short distances. A single rain gauge provides data only for its specific location, which may not represent a larger area accurately.
Addressing these problems requires careful installation, regular maintenance, proper calibration, and sometimes, the use of multiple gauges to ensure data accuracy and reliability.
SOLUTION
These problems were solved by the Portuguese company Ambimetric, which developed a cheap and reliable rainfall monitoring system using a cloud platform.
Rain Gauge – Senseca HD2015 Delta OHM (other models available), Datalogger Efento – Efento Wireless pulse counter
Ambimetric has developed a udometric station (rain gauge) that integrates a precipitation sensor and an Efento datalogger with NarrowBand IoT communication. Data is sent via the mobile network using a SIM card with a low annual cost.
The battery provides autonomy for up to 5 years of maintenance-free operation, thus saving the use of a solar panel or other power source.
