Abstract

A remote sensor device, method and system may include a casing housing an electronic circuit mounted that may include at least one environmental data sensor that generates environmental data based on one or more environmental conditions of air surrounding the environmental data sensor. The electronic circuit may also include a processor, a power source, a wireless transceiver, and a programmable memory. The environmental data generated by the at least one environmental sensor may be transmitted the environmental data via the wireless transmitter to a receiving device. The remote sensor device may also have a sensor to measure movement and the remote sensor device and/or portions of the circuit may enter a deep sleep mode when the motion is below a threshold level of motion and exit the deep sleep mode when the motion of the sensor device is at or above a threshold level of motion.
