Low-Power Odor-Sensing Network Based on Wake-Up Nodes
نویسندگان
چکیده
The localization of bad odors is a long standing issue with high relevance for affected people because of the health and safety implications. In order to enable the detection and localization of bad odors we propose a wireless, low-power consuming sensor network. The sensor nodes are designed to wake-up upon initial detection of a bad odor to then start to measure the strength of the odor. Taking into account the spatial variation of the bad odor as well as environmental parameters the odor source may be identified. After the odor vanishes the sensor nodes return to sleep mode.

متن کاملA Brief Review on Low Power Wake-Up Receiver for WSN
Wireless Sensor Network (WSN) consists of a large amount of low powered nodes which perform tasks like processing, radio transmission-reception, sensing and actuating. To minimize the power consumption in wireless sensor network a dedicated wake-up receiver is used within every sensor node. The wake-up receiver is an additional receiver, which continuously monitors the channel and wakes the res...
متن کاملLow Dropout Based Noise Minimization of Active Mode Power Gated Circuit
Power gating technique reduces leakage power in the circuit. However, power gating leads to large voltage fluctuation on the power rail during power gating mode to active mode due to the package inductance in the Printed Circuit Board. This voltage fluctuation may cause unwanted transitions in neighboring circuits. In this work, a power gating architecture is developed for minimizing power in a...
