Optical rain sensor
Description
This sensor utilizes the Hydreon Rain Gauge model RG-15, a commercial sensor, and connects to the SCORE network via Wi-Fi using an ESP32 data logger. This integration allows for accurate rainfall measurements to be wirelessly transmitted in real-time for analysis and application in weather forecasting, water resource management, and environmental monitoring.

| Easy | Limited - The sensor must be driven by a microcontroller (e.g., an ESP32), to which it must be connected with a cable prepared on purpose. The overall system must be housed in a box guaranteeing watertightness against humidity and eventually rain, and it should be provided to the citizens as an engineerized and functioning device. Finally, the system must be equipped with a battery and/or a solar panel, in case it cannot connect to the power grid from the location of installation. | Limited and mainly depending on the powering configuration, i.e., either connected to the power grid or with battery, since in the first case citizens must be able to safely connect the system to the power grid. Then, the optical probe of the sensor must be positioned in a way to maximize its exposition to rain, which often requires drilling a wall to fix the sensor support. | High - the system software will be pre-installed so that sensor functionalities like signal acquisition and processing will be transparent to the citizens, that will have only to login to the on-boarding app and launch the configuration procedures. (to be discussed: However, the software will be open and users with coding expertise will be given the possibility to modify and optimize it - this can add difficulties in data validation procedures) | local groups; local authorities |
