In recent decades, considerable efforts have been devoted to process automation in agriculture, Environmental Monitoring, Pollution Monitoring & Traffic Management in Emergency Situations. In these and many more such applications it is necessary to go beyond Wi-Fi based WSNs. In this work an attempt is made to design and implement a WSN that will operate in remote environment where Wi-Fi is not reachable. Each node consists of a ESP32 microcontroller, LoRa modem, GPS module and I2C interfaced-multiplexed sensors. Each node has the capacity to wirelessly intercommunicate with the rest of the nodes, sending the captured information to a central point (gateway), from which and through the web the information is stored in a server so that it can be analyzed and consulted in real time in the control centre for further monitoring and controlling of the necessary activities in such areas.
