A new and distinct cultivar of Gypsophila plant named \u2018Esm Rena\u2019, characterized by its erect and strong flowering stems; early, uniform and freely flowering habit; large luminous white-colored flowers with numerous petals and petaloids; and good postproduction longevity. The polymer composition contains a polyoxymethylene polymer that is directly or indirectly chemically attached to an impact modifier. Based on the detected parameter, the pressure in a balance chamber is controlled to adjust the compensating axial force generated by a balance drum. The wireless sensors can be in several example forms such as intrusion sensors, which are used for example in perimeter monitoring or motion sensing, fire or smoke sensors, glass breakage sensors, or temperature sensors.
