HotBox: Testing Temperature Effects in Sensor Networks

Low-power wireless networks, especially in outside deployments, are exposed to a wide range of temperatures. The detrimental effect of high temperatures on communication quality is well known. To investigate these influences under controlled conditions, we present HotBox, a solution with the following properties: (1) It allows exposition of sensor motes to a wide range of temperatures with a hi...

Reflectometry Based Quasi - distributed High Temperature Sensor

Pirani Pressure Sensor with Distributed Temperature Sensing

A Pirani pressure sensor is based on the fact that the thermal conductivity of a gas is dependent on the pressure. The structure presented in this paper consists of a heated microbeam, which is placed above a v-groove in a heat sink. The temperature distribution along the microbeam is a measure for the thermal conductivity of the surrounding gas. Measuring the temperature distribution instead o...

Fiber optic sensor for distributed liquid content quantification in subsurface

A novel fiber-optic sensor assembly for continuous monitoring of moisture over extended subsurface environments, such as road embankments, wall backfills, and landfills is presented. This sensor meets the requirements of subsurface monitoring by distributed measurements over linear positioning of a single fiber. The sensor assembly is composed of a communication optical fiber and a hydrophilic ...
