We have done much research with networks of sensors of various types. We have constructed and deployed many inexpensive sensor/logging devices for experiments. The backbone of these is an inexpensive data logging device which we have designed and constructed ourselves. This data logger device is battery powered, and can connect to various data producing devices and subsequently store all of the data to a flash memory storage device.

The image to the left shows one of our buoy sensors. This is deployed in a body of water, and can monitor various conditions of the water - temperature, cloudiness, etc. It also can radio the results back to a base station via the internal radio.

For test-burn fires, we have deployed weather stations like the one seen to the right. These inexpensive devices sit on a tripod and can monitor various weather conditions as fires pass near or over them. The electronics bundle is usually buried for tests like this to prevent damage.
