SMART GRID – ENERGY MONITORING & MANAGEMENT SOLUTION
Client: Own product /service for Energy sector, Pakistan
Status: Completed, July 2014. Upgrades ongoing.
Description: Built an energy monitoring solution for standard digital meters. The requirement was to make electricity metering data available online
without need to upgrade existing equipment. We developed an ultra-low power device that communicated with different meters based on the IEC-62056-
21 standard and transmitted the data via GPRS to the internet. This is the only inter-portability compliant solution that can be integrated with ALL the
existing metering infrastructure in Pakistan. Our energy monitoring nodes can be updated with new software features remotely via OTA updates. This
solution can be customized to be part of a wireless sensor network or work in stand-alone mode. The solution can also be modified to work globally and
measure electricity, water and gas flow. Our online dashboard gives users the ability to optimize energy usage and identify areas of improvement.
Tech: IEC 62056-21 standard optical comm interface, GSM/GPRS, Wi-Fi/RF/LoRa/ZigBee/BLE/Bluetooth (optional), energy harvesting with solar PV, Ultra-
Low power design, OTA updates, on-board data storage, Deployed advanced firmware development techniques for enhanced performance.
Applications: Large scale energy metering and monitoring solutions, Live energy Audits, power factor improvement systems, distribution transformer
monitoring, industrial power quality, Audit and power consumption/demand profiles, sub-station level monitoring and consolidation with Billing system
possible to detect electricity theft at transformer and utility levels.

REAL-TIME RFID BASED WIRELESS SENSOR NETWORK
Client: Confidential, Pakistan.
Status: Completed, August 2014. Updates ongoing.
Description: Real time pledge / donation collection visualization system. The client required this for various donor events where users could make
pledges via RFID wristbands and the all the collection total info is available in real time. We used BLE enabled RFID readers.
In addition to this, we also developed a proof of concept real time shop floor tracking system with scalable RFID read/write devices forming a wireless
sensor network monitoring the production of textiles on the factory floor in real-time. All RFID units were connected to a central Data Concentrator unit
(DCU) that was built for this particular application.
Tech: Proprietary RF solution, 433M/900M/2.4 GHz radios, NFC/RFID, BLE, REST API, MySQL, Meteor
Applications: Event Management, Access control, Attendance solutions, Supply chain traceability, shop-floor tracking, Warehousing, Shipment and
package tracking, security applications. Using E4 Tech’s domain knowledge, expertise we can connect any sensor to the cloud using any communications
/ networking technology and provide feature rich, affordable and high ROI solutions to businesses.
