Solar Panel Charge Controller - 10 A
Charge controller for photovoltaic applications controlled by a microcontroller and capable of operating automatically at both 12 and 24 V.
Overview
It allows to provide the right degree of current to the batteries protecting them from an excess of discharge or charge in order to prolong their life cycle as much as possible.
Attention! use only with 12 and 24 V solar panels.
It protects the battery from polarity reversal, automatically enters protection and locks when the load current exceeds the regulator’s range. In case of short circuit, it enters protection and it overload protection.
To avoid complete battery discharge, the regulator will automatically disconnect the load at a certain voltage that cannot be less than 11.2 V for the 12 V battery and 22.4 V for the 24 V batteries.

This project detects water leak and records the temperature and humidity reading at the time of leak and sends it to the Adafruit cloud.
By popular demand, we are pleased to announce that it’s now possible to buy the Arduino MKR IoT Carrier. Originally forming a key part of the Arduino Oplá IoT Kit, we’ve responded to our community to make the carrier available on its own, thus enabling you to benefit from having a bunch of sensors, actuators, and a display all featured on the one board — making it quicker and easier to take your IoT projects to the next level. Featuring a large set of built-in sensors and actuators as well as a useful color display, the carrier lets you focus on prototyping your IoT ideas right away by saving on the hassle of wiring and soldering these components. The carrier can become a WiFi, LoRa, NB-IoT or GSM-compatible device by seamlessly connecting to any MKR family board. Building a user interface for these boards is easy with the embedded color OLED screen, five capacitive touch buttons, and the five RGB LEDs. The integrated sensors (temperature, humidity, pressure, RGBC light, gesture and proximity) allow you to map the environment around the carrier, and should you need to capture any other data there are over 100 additional Grove sensors that can easily be connected directly to the carrier. Here’s are quick demo of the carrier's capabilities! (Special shout out to Mirko Pacioni and Filo Connesso for creating this demo.) Capture and store all the data locally on an SD card, or connect your MKR family board to the IoT Cloud for real-time data captured, storage, and visualization.
