“…Commonly used sensor modules rely on fixed heating resistors and fixed voltage for sensor heating. Additionally, these devices are often constrained by microprocessors and circuitry, and the presence of multiple functionalities tends to reduce the range of detectable gas types [4][5][6][7] .…”

Volatile organic compounds (VOC) gas detection devices based on semiconductor sensors have become a common method due to their low cost, simple principle, and small size. However, with the continuous development of materials science, various new materials have been applied in the fabrication of gas sensors, but these new materials have more stringent requirements for operating temperature, which cannot be met by existing sensor modules on the market. Therefore, this paper proposes a temperature-adjustable sensor module and designs an environmental monitoring system based on the STM32F103RET6 microprocessor. This system primarily utilizes multiple semiconductor gas sensors to monitor and record the concentrations of various harmful gases in different environments. It can also monitor real-time temperature, humidity, and latitude and longitude in the current environment, and upload the data to the Internet of Things via 4G communication. This system has the advantages of small size, portability, and low cost. Experimental results show that the sensor module can achieve precise control of operating temperature to a certain extent, with an average temperature error of approximately 3%. The monitoring system demonstrates a certain level of accuracy in detecting target gases and can promptly upload the data to a cloud platform for storage and processing. A comparison with professional testing equipment shows that the sensitivity curves of each sensor exhibit similarity. This study provides engineering and technical references for the application of VOC gas sensors.

“…Due to this, various problems like inhibition of plant growth, change in soil properties, and contamination of ground water occur (Mohanavelu et al, 2021). Irrigation water containing salt reduces overall crop yield and growth in salt-intolerant crops (Sharma et al, 2023). Similarly, it causes the death of aquatic organisms that rely on specific salinity levels to survive in their natural habitat, and it can be the cause of native vegetation death or poor health.…”

The salinity of water has a negative impact on both climate change as well as human health. Therefore, the in situ monitoring of water salinity is important. Numerous approaches, including electromagnetic inductive sensing, remote sensing, methods based on optical fiber sensors, conductive sensing (capacitive or resistive), can be used to measure the salinity of the water. This work focuses mainly on the design and fabrication of low-cost co-planar interdigitated (IDT) sensors with sensitive fringing field measurement capabilities. IDT sensors with configurations 1-1-1, 1-3-1, 1-7-1, and 1-15-1 were designed and fabricated in this work. The capacitance values for all four configurations decrease proportionally with water salinity, demonstrating a negative linear response in sensors that utilize water salinity levels as the dielectric media.
