La Cool Co. develops open source gardening platform aimed to improve the well-being of any kind of plant, and to be a toolkit for education on sciences and electronics. After Le Petit Cool (the world's first open source greenhouse kit), we are introducing Le Mini Cool, a small sensor module that is intended to be used by teachers and educators to teach electronics with a natural sciences approach (and vice-versa). It can be used as a toolkit to introduce both subjects to adults and children, and it monitors information regarding light, humidity, temperature and moisture for a specific plant, allowing people to have all the information they need to take action for the life of their plants.
