Abstract
In this work, we apply the sensor-network technology to the livestock industry. We concentrate on sensing of odors of livestock, such as ammonia. We distribute several nodes to the farm where livestock is raised, and send odor data to server, and enable the farmer to access to the data through the network, As a prototype, we implemented a circuit to save the odor data to SD card, and confirmed that the odor of ethanol was detected. We will make the data accessible from the network.
