Forests are increasingly exposed to natural disturbances, including drought, wildfires, pest outbreaks, and windthrow events. Due to prolonged droughts in the last years in Europe, European forest stands significantly lost vitality, and their health condition deteriorated, leading to high mortality rates, especially, but not limited to, Norway spruce. This phenomenon is growing, and new regions are being affected; thus, it is necessary to identify stress in the early stages when actions can be taken to protect the forest and living trees. Current detection methods are based on field walks by forest workers or deploying remote sensing methods for coverage of the larger territory. These methods are based on changes in spectral reflectance that can detect attacks only at an advanced stage after the significant changes in the canopy. An innovative approach appears to be a method based on odor mapping, specifically detecting chemical substances which are present in the forest stands and indicate triggering of constitutive defense of stressed trees. The bark beetle attacking a tree, for example, produces a several times higher amount of defense-related volatile organic compounds. At the same time, the bark beetle has an aggregation pheromone to attract conspecifics to overcome the tree defense by mass attack. These substances can be detected using conventional chemical methods (solid-phase microextraction fibers and cartridges), and it is proven that they are detectable by dogs. The disadvantage of classic chemical analysis methods is the long sampling time in the forest, and at the same time, the results must be analyzed in the laboratory using a gas chromatograph. A potential alternative novel device appears to be an electronic nose, which is designed to detect chemical substances online (for example, dangerous gas leaks or measure concentrations above landfills, volcanic activity, etc.). We tested the possibility of early-stage stress detection in the forest stands using an electronic nose Sniffer4D and compared the individual sensors in it for detecting the presence of attacked and dead trees. Our results indicate the promising applicability of the electronic nose for stress mapping in the forest ecosystem, and more data collection could prove this approach.

“…The ESP32 chip is widely used in numerous fields, according to recent research studies. A microcontroller may be used with a broad range of environmental monitoring sensors [12], whether it's to monitor air pollution or to directly monitor LPG leaks [13]. The article [14] shows how to utilise ESP32 as a control system to support wireless networks.…”

Water quality in breeding tank plays a significant role when breeding the fish because optimal water quality is significant as these environmental changes will affect young fish to grow successfully. In order to ensure an optimal water quality in the fish breeding tank, an automatic and IOT based monitoring system is essential to replace the conventional monitoring which is done manually. In this paper, Jade Smart 1.0 was developed as a IoT based monitoring system of water quality in the breeding tank which consists of three identical boxes equipped with ESP32 as microcontroller, pH sensor, water temperature sensor and water turbidity sensor. This smart monitoring system is capable to digitally collect, store and display the water quality data in real-time through web and mobile phone applications. Jade Smart 1.0 was tested with three different points known as point A, point B and point C, in real local fish breeding tank in Seremban 2, Negeri Sembilan. Point A was located at the incoming water source, point B, at the corner of the tank opposite of the incoming water and point C, at the corner opposite of point B. The result showed that the average pH level at three locations for water depth of 10cm was pH 6.48 and at water depth of 20cm, dropped to pH 6.40. The maximum difference was 2.6% while the minimum difference was 0.6%. For water temperature at three locations at the water depth of 10cm, the average reading was 28.6°C while for water depth of 20cm, the average reading dropped to 28.3°C. The maximum difference of 1.7% and minimum difference of 0.3% were found. Next, for water turbidity, the location A measured an average of 3.3NTU while location B and location C measured an average reading of 9.8NTU and 9.9NTU respectively.

Potential integration or cooperation of the Internet of things (IoT) systems and the blockchain technology is nowadays attracting remarkable interest from the researchers. These inter-operating systems often have to rely on lowcost, low-power, and robust IoT devices that can communicate with the blockchain network through smart contracts.In this work, we designed and ran a benchmark study for ESP32-based lightweight IoT devices interacting within the Quorum blockchain. A software library was built for ESP32 devices to enable elliptic-curve digital signing, Keccak-256 hashing, decoding, encoding, and secure private key generation capabilities, which all are the basic functional requirements for running a blockchain client. The running times and power consumption values of these essential operations were analyzed and discussed in detail. We also deployed two smart contract functions on the Quorum network and analyzed the performance of the IoT device while interacting via these methods. Further optimizations were proposed and implemented to speed-up the processes and save energy, which resulted in a 2.5x increase in the transaction posting speeds and a 2/3 decrease in the energy costs. Another performance comparison between an ESP32 and a PC client was also provided with.
