“…It can handle a high current of up to 3.2A and a maximum voltage of up to +26 V [33]. In previous research, the INA219 sensor has been utilized for voltage measurements [34,35], current size [36][37][38][39][40][41][42][43], voltage and current measurement [44]- [54], and for the voltage, current and power consumption [55][56][57][58][59][60]. We modified the microcontroller program of the INA219 sensor on TTGO LoRa ESP32 to be used to determine the earth's resistance.…”

Geo-electrical resistivity methods are widely used in various fields and have significant applications in scientific and practical research. Despite the widespread use of resistivity methods, current injection is a critical step in the process of resistivity methods, and the quality of current injection significantly impacts the accuracy of the resistivity measurements. One primary challenge is optimizing current injection techniques to enhance resistivity methods. The developed current injector model for the resistivity meter instrument enhances performance by increasing the voltage source to 400 Volts, extending measurement coverage. It provides three injection current options, 0.5A, 0.8A, and 1A, for efficient accumulator use, considering electrode distances and estimating earth resistance using Contact Resistance Measurement (CRM) to estimate the earth resistance. CRM mode ensures proper electrode connection before injection, thus improving measurement efficiency. The embedded TTGO LoRa ESP32 SX1276 facilitates wireless communication over 1.5 km, addressing challenges in remote and internet-limited areas. The model demonstrates reliability, validity, and durability in CRM mode and current injection measurement. Regarding reliability, we determine the relative error of the model by carrying out measurements repeatedly. In lab-scale testing, the average Relative Error in CRM mode is 0.65%, and in earth resistance measurement testing, it is 1.58%. These relative errors are below the 2% maximum error applied in the “Supersting”, a commercial resistivity instrument. The model's validity is defined by comparing the model with the measuring instrument; we have absolute error. In lab scale testing, the average Absolute Error in CRM mode is 3.08%, and in earth resistance measurement testing, it is 3.73%. The model's durability is tested by injecting current for a minute. After one minute of current injection, the power resistor component's temperature is stable at 30°C.

“…Cloud systems are advantageous for research experiments where live sensors are spread across vast distances. Ecology and marine biology experiments use cloud biology to control a fleet of sensors as they traverse through vast ecosystems, like forests and oceans [ 13 ]. Such systems have been used to protect the environment through disaster management by monitoring information in sparsely populated areas [ 14 ].…”
