• In the GSMA project, I worked with the RK900-12 Ultrasonic Automatic Weather Station and SKU 6357/6357M. The RK900-12 instrument is designed to measure various weather parameters, including wind speed, wind direction.
• In the Welimada area of the Badulla District, I worked on a USAID project aimed at providing agricultural devices to farmers. As part of this project, I prepared and installed 130 sensor and controller devices in.
• Operation of technical systems within an organization. I do System Monitoring and Maintenance,Troubleshooting and Issue Resolution, Infrastructure Deployment and Configuration, Documentation andKnowledge Sharing.
• LoRa and LoRawan Technology Using Controls the Temperature In this project, I monitortemperature using both LoRa and GSM communication. I have established LoRa and GSM communicationsystems.(LoRa and LoRaWan, GSM.
• LoRaWAN GATEWAY using an ethernet cable and get data I used the ethernet cable and get datafrom Gateway using local sever (GATEWAY,Linux OS)
