Recent past Nirmitsu's major focus has been shifted to Power industry. The fast development happening in the areas of renewable energy, advancement of new technologies in distribution, centralized streetlight control for the Village/Municipal bodies, development of new LED based streetlights with lesser consuption of power, power on demand, smart metering and other technological advancements allowed Nirmitsu to do a constant R&D and innovation in the areas of Power industry. As a company Nirmitsu started to innovate in the areas of Power and SmartGrid in early 2009. The company's major focus on developing Wireless based Smart Grid and Power management solutions allowed them to bring and integrate a Web based management console to manage lighting devices indoor and outdoor in 2010.

The solutions developed by Nirmitsu was initially focussed on to integrate Wireless modules(NURF100 B1-B6 series modules) based on 802.15.4 to their Nirmitsu CloudRFMS(Nirmitsu SmartEnergy Web product) or Nirmitsu SMS to provide monitor and control capabilities.

Initially Nirmitsu Wireless modules are capabile of generating a unique RF integration with their Control Terminal NU2100.

The product has demonstrated in late 2010 to Govt of Karnataka by 3rd party vendors. The solution was developed to handle different needs of industry by focussing only to develop Wireless modules and Control Terminals.

  • NURF100 B1-B6 RF modules
  • WiFi 802.11 b/g modules
  • NU2100W - Wireless Smart energy controller communicating to NURF100 B1-B6/WiFi mesh modules one side and Uses SMS/GPRS/3G connection to centralized server to provide localized feeder pillar control.

The NURF100 modules had the capabilities to provide a

  • Zigbee/6lowpan/Mesh networking for streetlights The devices can talk to NU2100W/NU2100 control terminal and can be configured with secured connection from Remote server to store local energy profiles. The energy profiles can be dynamically reprogrammable to the device for controlling street light at different things like night, day, evening, dawn, etc. The device has also integrated with temperature sensor to check the present condition in the area to provide some unique information about weather conditions. The device also provides internal temperature condition of the box to check the life of steetlight. The device also has photo transistor to detect the daylight condition.

The NURF100 modules provide the unique capability to connect the devices NU2100 in mesh or infrastructure mode.

NURF100 will work in

  • Router mode
  • Co-ordinator mode
  • End device mode.

The device will provide Control and Data communication mode Where in control mode after the secure channel established it will allow to send data in ASCII AT mode to control application for changing the configuration. The binary data communication will allow the synchronous state of the device to be monitored and present device conditions like device in failure, device disconnected, device present profile or PWM value, device present state will be reported to Web console.

NU2100W/NU2100 devices can transmit the data to centralized server Nirmitsu CloudRFMS to log the data in regular interval. The NU2100 device can also store and forward data on regular intervals to avoid a huge traffic from all devices implemented in a area/city/village. The synchronization can be configured in different intervals to the Web server and device has following capabilties

  • keep alive messages to server and NURF100 devices
  • GET/SET device state
  • GET device conditions
  • GET RF device data
  • Device Scanning and enumeration and reconfiguration from server
  • local data logging
  • Forward and synchronize data with central server
  • provide SMS/GPRS/WiFi monitoring
  • provide maintenance mode for network remap.
  • provide networking unique indentification mechanism.

The unique capabilities of above devices allowed to develop a unique solutions in early stages of emergence of Internet of Things(IOT).

As a company Nirmitsu provides

  • RF and Wireless modules for Smart Energy management
  • Lighting controllers with pwm support for LED street lights and indoor lighting.
  • Integrated support for multicolor lighting and RF device with OWM output can provide a unique control of lights and bulbs to provide good indoor experience and ambience.
  • The supprot for 3rd party AVS/Oower controllers, Contactors will allow them control traditional tubelights, streetlights based on power requirements.
  • The capability of Wireless sensor allowed NURF100 device to work with AC/Chiller controller monitoring.
  • The GPIO/PWM control provided by NURF100 will allow the Screen Control of Windows and Doors in houses by providing BLDC motor control through wireless.
  • The capability to handle the incoming Analog data using ADC will allow the NURF100 to detect the level value produced by level sensor and provide a unique wireless water level detection solution.
  • The capability to send GPIO signal will allow the NURF100 to control hooters to generate a alarm based on the people present detected using light/IR based human detection sensor which uses techniques like generating digital pulses detecting human or animal
  • The capability to Detect the human present allowed to develop a unique applications like "Auto presence Detection and Energy management System" to turn off lights in the conference rooms based on people in availability. This application is extended to Malls and has been tested in Malls of Bangalore by Nirmitsu. The application will help Nirmitsu to detect the people present in the area based on different technic and IP of Nirmitsu and provide appropriate lighting.
  • The capability build wireless alarms and lighting system will allow them to implement these in Transportation area like Bangalore Metro Railway or any other Metro projects to manage the lights from remote place and tune the lighting based on people availability and provide a unique Power saving.
