Disclosed is a method of gathering data from a hybrid RFID chip to determine usage of an item or article of clothing using a mobile device like a phone, laptop, or tablet. The hybrid RFID chip consists of a processor, a memory, a radio transceiver, a power harvesting antenna, and an impedance circuit that converts ambient radio frequency (RF) energy to electrical energy. The RFID chip receives a first power level from ambient RF energy and periodically broadcasts an identity. The mobile device can receive the broadcast identity, store the identity, transmit the identity and location to a remote server, and receive a notification message from the remote server. The remote serve can determine usage of the item or article of clothing by comparing current records to previous records of RFID chip identity, location, and mobile device application identity.

System and method for collection, control and wireless transmission of environmental and other data. Nodes may wirelessly connect to other nodes to relay node specific information, collected sensor data or commands to and from other nodes and gateway nodes linked to a central database. Nodes in gateway mode may be capable of aggregating and relaying commands and data between other nodes and a centralized database. Nodes may bypass other nodes and/or gateway nodes and communicate directly with the central database via satellite or cellular link. Nodes may be self-contained devices, inclusive of a wind or solar power source and a battery, eliminating the need for an external power source. Nodes may be configured independently or as a system to monitor and control various types of equipment including utility lines or water systems or used to collect environmental data. Nodes may communicate on different channels/frequencies based on systematic or pseudo-random changes.
