Abstract

A cell-phone based chemical sensor and communication/data management system has cell phones that are each provided with an integrated sensor (sensor enabled cell phone). Each cell phone comprises an infrared spectrometer for spectrally analyzing the ambient environment and a communication portion for communicating with the cellular phone network and transmitting data from the infrared spectrometer over the cellular network. These cell phones are linked to each other and a central server via the routing nodes of the cellular phone network.

Claims

1. Sensor network, comprising:

a cellular phone network; and

sensor enabled network nodes, each one of the nodes comprising;

an infrared spectrometer for spectrally analyzing the ambient environment, and

communication portion for communicating with the cellular phone network and transmitting data from the infrared spectrometer over the cellular network.
