PTM 330

ENOCEAN  PTM 330  模块, 无线发射器/开关, 868MHZ

The is a radio transmitter module enables the implementation of wireless sensors and switches without batteries. The PTM 330 can be connected to ECO 200 via a contact spring. There are two meander structures on the PCB which allow usage of a rubber pad to set the level of two digital inputs. Alternatively PTM 330 can be mounted as an SMD component onto a host PCB. In this case energy supply pins and digital input pins are accessible via contact pads. The functional principle of this module is when an energy pulse is supplied e. g. by the motion energy harvester ECO 200 an RF telegram is transmitted including a unique 32bit module ID, the polarity of the energy pulse and the operating status of 4 digital inputs. The RPS telegram content can be configured if other content is needed.
