Moisture that is possibly present in an integrated circuit is detected autonomously by the integrated circuit itself. An interconnect region of the integrated circuit includes a metal level with a first track and a second track which are separated by a dielectric material. A detection circuit applies a potential difference between the first and second tracks. A current circulating in one of the first and second tracks in response to the potential difference is measured and compared to a threshold. If the current exceeds the threshold, this is indicative of the presence of moisture which renders said dielectric material less insulating.

A storage racking system for plant products can be capable of automated rotation and curing of dried cannabis and hemp flowers in sealed containers, which can maintain relative humidity along with a UV light and oxygen deficient environment to reduce degradation. The storage containers can be positioned horizontally to maintain a connection to the inert gas connection and allow for daily rotation in either direction. Each storage container can have a lid and a humidity pack. The lid can have a pressure relief valve that can exchange the gaseous atmosphere from the storage container with an inert gas through a check valve connection. The humidity pack can maintain the relative humidity in the storage container at about 58% to 62% during the curing and storage stages.

A wearable environmental sensor device includes a temperature/humidity sensor disposed on a wall surface of a housing that is exposed to an environment and configured to measure ambient environmental information around a living body, and a protective structure formed around the temperature/humidity sensor. The temperature/humidity sensor is disposed, directly or via a support structure, on or over the wall surface of the housing, wherein the wall surface faces substantially downward from the living body when the wearable environmental sensor device is attached to the living body and the living body is in a standing posture. The protective structure has respective ventilation holes provided in two or more pairs of opposed surfaces thereof each facing in a direction other than a vertical direction of the living body when the wearable environmental sensor device is attached to the living body and the living body is in the standing posture.

A gas sensor for sensing a gas in a humid environment includes a first electrode layer, a second electrode layer that is spaced apart from the first electrode layer, and a gas sensing layer that electrically interconnects the first electrode layer and the second electrode layer.

At least one of the first electrode and the second electrode includes a first portion 111 having a first surface area at a first position in the longitudinal direction, and includes a second portion 112 having a second surface area larger than the first surface area at a second position in the longitudinal direction different from the first position.

A thin film gas sensor device includes a substrate, a nanostructured thin film layer, and a first and a second electrode. The nanostructured thin film layer is supported by the substrate and is formed with a semi-conductor material including holes. The semiconductor material is configured to undergo an increase in a density of the holes in the presence of a target gas, thereby decreasing an electrical resistance of the nanostructured thin film layer. The first and the second electrodes are supported by the substrate and are operably connected to the nanostructured thin film layer, such that the decrease in electrical resistance can be detected.

Ultraviolet radiation is directed within an area. Items located within the area and/or one or more conditions of the area are monitored over a period of time. Based on the monitoring, ultraviolet radiation sources are controlled by adjusting a direction, an intensity, a pattern, and/or a spectral power of the ultraviolet radiation generated by the ultraviolet radiation source. Adjustments to the ultraviolet radiation source(s) can correspond to one of a plurality of selectable operating configurations including a storage life preservation operating configuration, a disinfection operating configuration, and an ethylene decomposition operating configuration.

A method of and system for detecting a gas or vapor includes providing a sensor comprising an electrode pair in electrical contact with a layer of porous material, the porous material layer having water adsorbed on its surface; contacting the sensor with a gas or vapor sample to be analysed; applying a voltage across the electrode pair of the sensor; and measuring a response, the response correlating to the presence of a target gas or vapor.
