The status of a device is continually monitored by a processor or programmable circuitry that has a powered on mode and a powered off mode. The device includes a short range wireless transceiver which allows the status data to be communicated via a wireless connection to an external wireless communication device, whether the processor or programmable circuitry is in the powered on mode or the powered off mode. The wireless communication device, in turn, transmits the status data to a maintenance/repair/monitoring facility via a communication network. This facilitates monitoring of the device in a non-intrusive manner and streamlines maintenance of the device. The wireless communication device also receives information from the external communication device, including information relevant to the operation of the device, and updates the status data based on the received information. This facilitates updates to the device, as needed.

A system includes a data acquisition device that includes one or more sensors. The data acquisition device collects sensor data from the one or more sensors that measure one or more of the following: irrigation flow rate, irrigation water quality, intensity of solar radiation, ambient temperature, and ambient humidity. The system further includes a user interface module that collects condition data from a user. The system further includes a collection and analysis application that receives the sensor data from the data acquisition device, receives the condition data from the user interface module, analyzes the sensor data and the condition data, and generates analyzed data from the sensor data and the condition data. The user interface module generates a user interface that includes the analyzed data from the collection and analysis application.

A measurement system comprises a measurement unit, a transmitter, an autarkic power unit and a control unit. The measurement unit measures a quantity repeatedly and the transmitter connects the measurement system to a network and transmits data to the network based on the measurements of the measurement unit. Further, the autarkic power unit supplies electrical energy to the measurement unit, the transmitter and the control unit. Additionally, the control unit controls the measurement of the quantity and the transmission of data dynamically based on a currently available amount of energy provided by the power unit. Further, the control unit stops measurements by the measurement unit and keeps the transmitter connected to the network, if the currently available amount of energy is below a predefined energy limit indicating that the currently available amount of energy is too low for taking measurements and for keeping connected to the network.

An observation system includes: a power supply unit having a battery; a sensor unit which detects a state of a structure on the basis of electricity from the power supply unit; a charging unit which charges the battery from renewable energy; and a processing unit which processes sensing information in one observation mode of a plurality of observation modes including at least a first observation mode and a second observation mode in which at least one of a sensor capability of the sensor unit and a load of computational processing using the sensing information is higher than in the first observation mode. The processing unit sets an observation mode on the basis of information for disaster occurrence estimation.

Systems and methods are provided for a distributed mufti-sensor witness integrity sensing platform (WISP) approach which allows for positioning of sensors in an enclosed space. In particular, a WISP platform is divided into two modules, with a base module is connected to multiple edge sensor modules with a wired connection. In general, splitting up the distributed WISP system described herein allows multiple sensors to be placed in an enclosed (and generally inaccessible) location. The senor data can be transmitted from the multiple edge sensor modules via a connection to the base module. Additionally, the use of the two module system as provided herein allows the sensors to be positioned meters away from the first module.
