Devices and systems for determining personal outdoor comfort are described herein. One device includes instructions executable to receive inputs corresponding to characteristics of a user associated with a mobile device, determine a location of the mobile device, communicate an indication of the characteristics and the determined location to a computing device, and receive an outdoor comfort determination from the computing device, wherein the outdoor comfort determination is particular to the user based on the characteristics of the user and particular to the location of the mobile device based on a plurality of environmental parameters associated with the location of the mobile device.

Environmental measuring device comprising a central processing unit connected to a group of environmental sensors contained in an air duct comprising a fan suitable for aspirating ambient air via an air inlet and for discharging same via an air outlet.

A real-time metocean sensor array system may include a one or more floating instruments each including geolocation capabilities and connected to a satellite communication network. In some examples, the floating instruments may further include an omnidirectional hydrophone. Motion and acoustical data gathered by the instruments may be converted by onboard processing logic into wave, current, and/or wind-related observations that may be communicated in real time and analyzed via a cloud-based system.

Movement of photovoltaic panels is measured using an array of low-cost devices. Accelerometers are mounted on photovoltaic panels across a site to measure wind speed and direction. Time stamped data from the devices is transmitted to a central computing device which calculates a rolling, lagging wind speed and direction. Measured movement of the photovoltaic panels is used to determine when to place photovoltaic panels in a protective stow mode to reduce damage during a wind event.

A distributed weather system includes a storage, a plurality of wireless weather stations, a server, and an interface. Each of the plurality of wireless weather stations is associated with a user and has a battery, a location sensor generating location information, an anemometer generating apparent wind speed, a transmitter transmitting the location information with the apparent wind speed to a network at periodic intervals, and a receiver receiving control commands that include a length of the periodic intervals. The server receives the location information with the apparent wind speed and stores them in the storage. The interface is accessible by a mobile computer, and receives the control commands from a user and sends them to the receiver of the wireless weather station associated with the user. The interface displays a true wind speed for each of the plurality of wireless weather stations, which is calculated using the apparent wind speed, the location information, and historical location information.

Described herein is environmental sensors, sensor units, sensor systems and/or sensing methods. In particular, an agricultural or horticultural environment multi-sensor unit comprising a plurality of environmental sensors, including at least: an incident light sensor, a temperature sensor, a carbon dioxide sensor and a relative humidity sensor. The sensor unit may also comprise a wireless communication interface, the multi-sensor unit being configured to transmit data from the environmental sensors via the wireless communications interface.

A rain gauge is disclosed and includes a collection cylinder and a rain gauge head. The rain gauge head includes an intake opening and a vane tail, with the vane tail redirecting the intake opening to face oncoming wind and rain so that the intake opening collects oncoming rain. The rain gauge head includes a rainwater discharge to deposit rainwater within the collection cylinder. The rainwater discharge may be rotatably fastened to the collection cylinder so that the rain gauge head is free to rotate around a vertical axis for 360 degrees. Alternatively, the rain gauge head and collection cylinder may rotate in unison. An air exhaust port and air pressure relief valve may be formed in either of the rain head gauge or collection cylinder to release air trapped within the rain gauge. Airfoils may be placed on the collection cylinder to better redirect the rain gauge.
