Abstract:The recent adjustments in climate have multiplied the significance of environmental tracking, making it a topical and surprisingly active studies region. This Wi-Fi ld is based on remote sensing and on wireless sensor networks for gathering statistics about the environment. Current improvements, such as the vision of the internet of things (IoT), the cloud computing model, and cyber-physical structures, offer aid for the transmission and control of big amounts of information concerning the trends determined in environmental parameters.In this context, the present day paintings offers three specific IoT-primarily based Wi-Fi sensors for environmental and ambient tracking: one using user datagram protocol (UDP)-based totally wireless verbal exchange, one communicating thru Wi-Fi and hypertext transfer protocol (HTTP), and a 1/3 one using Bluetooth clever. All the offered systems provide the possibility of recording facts at far flung places and of visualizing them from each device with an internet connection, allowing the tracking of geographically massive regions. The improvement details of those systems are described, along with the predominant variations and similarities among them. the feasibility of the 3 developed structures for implementing monitoring packages, considering their power autonomy, ease of use, answer complexity, and net connectivity facility, turned into analyzed, and revealed that they make excellent applicants for IoT-primarily based solutions.

“…Complementary metal–oxide–semiconductor (CMOS) monolithic active pixel sensors (MAPSs) offer low power consumption, radiation resistance, high reliability, and cost effectiveness; in addition, they exhibit great application potential in the field of ionizing radiation monitoring [ 1 ]. In recent years, MAPS-based ionizing radiation detection has been used extensively in interventional radiology to monitor individual doses of doctors and patients [ 2 , 3 , 4 ] and charged particle track detection [ 5 ]. In addition, applying this optical device to detect nuclear radiation has attracted considerable attention [ 6 ].…”

This study presents a real-time monitoring technique for radioactive substances that meets safety management needs. We studied the accumulation characteristics of radiation response signals of monolithic active pixel sensors (MAPSs) based on their response and discrimination ability to gamma (γ) photon or neutron radiation. The radiation status of the radioactive substances was determined by monitoring the accumulation data of radiation responses. As per the results, Am-Be and 252Cf radiation response signals are primarily concentrated in the range of 0–70 pixels. Response signals of 60Co and 137Cs γ-ray were concentrated in two regions; there was a peak in the region with a pixel value of less than 50, and a plateau in the region with a pixel value of more than 75. Therefore, the results are able to discriminate between spectra. Furthermore, we designed a radioactivity monitoring system that is able to examine multiple radioactive materials. Its working principle is that a change in the accumulation of radioactivity monitoring data indicates a radiation change during the last accumulation cycle. This study provides vital technical support for the long-term supervision of radioactive substances.

“…It has been reported that MAPS has good linear response characteristics for X-rays with energy greater than tens of keV. The dose rate detection uncertainty is less than 10% [ 1 , 2 , 3 ]. The detection accuracy depends on the calibration factor when there is no shielding structure and collimator, but the ray incidence angle has little effect on the detection results [ 5 ].…”

Herein, we report the γ-ray ionizing radiation response of a commercial monolithic active-pixel sensor (MAPS) camera under strong-dose-rate irradiation with an online detection and monitoring system for strong radiation conditions. We present the first results of the distribution of three types of MAPS camera and establish a linear relationship between the average response signal and radiation dose rate in the strong-dose-rate range. There is an obvious response signal in the video frames when the camera module parameters are set to automatic, but the linear response is very poor. However, the fixed image parameters are not good at adapting to the changes of the environment and affect the quality of the video frames. A dual module online radiation detection and monitoring probe was made to carry out effective video monitoring and radiation detection at the same time. The measurement results show that the dose rate detection error is less than 5% with a dose rate in the range of 60 to 425 Gy/h, and the visible light image does not have obvious distortion, deformation, or color shift due to the interference of the radiation response event and radiation damage. Hence, the system test results show that it can be used for online detection and monitoring in a strong radiation environment.
