Abstract
The present invention provides a water tension sensor with a non-sintered core that allows batches of similar and standard sensors to be manufactured in a simple manner, for operation with air and with an air flow outlet, which sensor can be used to read water tension and trigger dripping. The sensor according to the invention is ideal for manually reading soil water tension and for automating irrigation systems based on a static pressure or gas propulsion mechanism.
