“…Despite this, a better approach to providing and utilizing power and energy to the WSN is required [39], [40]. One widely accepted method for extending the life of a network is imposing restrictions on node operations [41], [42]. Another potential solution to the energy problems of WSNs is to harvest ambient energy.…”

The rapid expansion of Internet of Things (IoT) devices and applications has accelerated research in various areas of human development. However, the cost of commercial instrumentation impedes the momentum of technological growth in developing regions. In this study, a low-cost, low-power, wireless sensor network for groundwater monitoring (LWNGM) was developed to provide near real-time groundwater level data to support prudent decision making in groundwater resource management in Zanzibar, Tanzania. To facilitate reproducibility, we provided a detailed description of the LWNGM development procedure. The system is based on the ATmega328P microcontroller platform and incorporates low-cost MS5803-14BA and MB280 sensors. To provide a low-power scheme, the Arduino UNO wakes up in six-hour intervals for measurements and data-logging to the SD card, and at twelve-hour intervals for relaying data (in batches) to the LoRa gateway, before it goes back into a deep-sleep mode for the rest of the time (duty cycle<1% ). The average power consumption for the end node across all system cycles was 104.081mW. The power autonomy of all nodes is provided by a 3.7V, 5000mAh rechargeable LiPo battery, and a 9V, 600mAh rechargeable Liion battery, respectively, which are supported by 6V and, 3W solar chargers. The data processing and storage components, as well as the data visualization dashboard, were created using free and open-source software. The LWNGM was reasonably priced, ranging between $350 and $400. The proposed system allows for the adoption of hydrological monitoring, particularly in areas with a limited budget for hydrologic management.

“…To this end, the commercial off-the-shelf LoRa-based transceiver module RFM95 from HopeRF was used [ 36 ]. This transceiver and therefore the communication technology were previously tested by the authors under different scenarios [ 28 , 37 , 38 , 39 , 40 ]. It is a module featuring long-range spread-spectrum communication links and high immunity to interference whilst optimizing the power use.…”

Characterization of dynamics inside clouds remains a challenging task for weather forecasting and climate modeling as cloud properties depend on interdependent natural processes at micro- and macro-scales. Turbulence plays an important role in particle dynamics inside clouds; however, turbulence mechanisms are not yet fully understood partly due to the difficulty of measuring clouds at the smallest scales. To address these knowledge gaps, an experimental method for measuring the influence of small-scale turbulence in cloud formation in situ and producing an in-field cloud Lagrangian dataset is being developed by means of innovative ultralight radioprobes. This paper presents the electronic system design along with the obtained results from laboratory and field experiments regarding these compact (diameter ≈30 cm), lightweight (≈20 g), and expendable devices designed to passively float and track small-scale turbulence fluctuations inside warm clouds. The fully customized mini-radioprobe board (5 cm × 5 cm) embeds sensors to measure local fluctuations and transmit data to the ground in near real time. The tests confirm that the newly developed probes perform well, providing accurate information about atmospheric turbulence as referenced in space. The integration of multiple radioprobes allows for a systematic and accurate monitoring of atmospheric turbulence and its impact on cloud formation.

“…WSN saat ini banyak menggunakan teknologi Zigbee, namun kendala yang dihadapi pada teknologi ini adalah kelemahan pada protokol keamanannya [11], jangkauan yang pendek dan tidak terlalu jauh. Pengembangan teknologi dalam komunikasi perangkat kemudian diusulkan dimana LoRa menjadi salah satu pilihan yang saat ini beroperasi pada frekuensi tidak berlisensi [12].…”

Pemantauan kondisi suatu keadaan dengan menggunakan sensor semakin dibutuhkan untuk mengamati perubahan kondisi dari waktu ke waktu. Data-data yang didapatkan sensor kemudian dikirimkan ke sistem pengumpul yang telah disiapkan melalui saluran jaringan telekomunikasi. Pengirimanan data pada perangkat-perangkat jaringan telekomunikasi yang disebar pada lokasi-lokasi tertentu yang kurang aman diberbagai keadaan memungkinkan data tersebut rentan untuk diambil dan dipalsukan. Sistem pengamanan berupa kriptografi dan hashing kemudian digunakan untuk melindungi data agar sampai dengan baik ke penerima. Pada penelitian ini diterapkan sistem keamanan dengan mengimplementasikan algoritma kriptografi asimetrik RSA 2048 bit dan algoritma hashing SHA-3 pada pengiriman paket data yang dikirim. Hal ini dilakukan agar data bisa terjaga keasliannya dan tidak bisa dibaca oleh orang yang tidak berhak jika data tersebut didapatkan. Setelah dilakukan pengujian dengan mengirimkan paket data dari pengirim ke penerima dengan beberapa variasi jarak, didapatkan bahwa ada selisih waktu saat data dikirimkan tanpa menggunakan keamanan dan saat menggunakan keamanan SHA-3 dan RSA 2048 sebesar 70,96603 ms.
