 Up here we have our power monitor device that is deployed at the front building. We are sending the data back using this Wi-Fi antenna to our server at H&EI. The device is connected to the main breaker here to monitor the power usage at this building. And we are comparing it to these commotion meters to see what is the accuracy of our device. This is the latest hardware revision of our power monitor. We have three-minute component on this board. There's input board which connects to these weatherproof connectors. The input board then goes down and connects to what we call the motherboard. The motherboard contains the power monitor chip itself as well as an FPGA chip, which stands for Field Programmable Gate Array. The FPGA handles the IO to the power monitor and then sends it back to our COM board up here. The COM board contains the GPS chip, the mesh network chip, as well as the LTE modem for communication back to our server. And everything is connected to this single board computer which acts as the brain for our whole system.
