Building environmental sensor method and system for collecting data from same

A building environmental sensor, comprising:

• a sensing element for collecting measurements of one or more of the following parameters of an environment in which the sensing element is present:
• temperature, humidity, light, sound or the absence or presence of a gas;
• a data store for storing data that is collected by the sensing element;
• a processor;
• a transmitter configured to transfer data according to a communication protocol;
• and
• a memory containing programming instructions that are configured to cause the processor to:
• detect, in response to communicatively connecting with a first data collection device via a short-range communication or near-field communication (NFC) protocol, that the first data collection device is within a communication range of the building environmental sensor,
• generate a first data stream that includes the data stored in the data store,
• transmit the first data stream to the first data collection device,
• determine that a communication link between the building environmental sensor and the first data collection device was lost before the first data stream was fully transmitted to the first data collection device,
• save an indicia that identifies remaining data in the data store that was not delivered to the first data collection device,
• detect, in response to communicatively connecting with a second data collection device via the short-range communication or NFC protocol, that the second data collection device is within the communication range of the building environmental sensor,
• generate a second data stream that includes the remaining data, and
• transmit the second data stream to the second data collection device.
