Abstract
The present sensor device, system and method provides tools for measuring, recording local environmental conditions, such as temperature and humidity, and wirelessly transmitting the collected data to a server. The sensor device is configured to, under normal operation, maintain the connection between the wireless network interface controller and the wireless local network so that various commands and/or communications can be received, whether the sensor device is in a low power mode or in an active mode. The sensor device cycles between the low power mode and the active mode, and back to the low power mode. Where in each active mode cycle, the sensor device is configured to acquire a measurement from sensor for storage in local memory, and/or transmit historical data acquired to the server, and/or check for updates by connecting to the server. By normally remaining in a low power mode and only waking periodically to conduct a task, battery life is greatly extended.
