How to use the potential of DFRobot Gravity
Automation of simple activities and systems that relieve us of our duties are almost standard for which Gravity sensors are used. Although it may seem that humidity, temperature or even soil pH sensors will be useful in home gardens and weather stations, they are often able to improve the operation of large farms. Growers can constantly monitor soil parameters, weather or surroundings, intervening when necessary.
Gravity Arduino is also perfect for private facilities, office buildings, production halls and warehouses. Gas or temperature sensors can indicate failures or problems, informing people in the room or the immediate vicinity that an irregularity has occurred that may turn out to be a threat.
The more elements and sensors that make up the protection system, the safer your property or company is.
