Mumbai, India : Pammvi provides unique, affordable and easy to install energy saving solutions for lighting and air conditioning management.

EnOcean wireless transmitters generate their energy from the environment.

This energy harvesting enables wireless and batteryless switches and sensors for building, home and industrial automation. In addition to transmission reliability and long wireless range, applications of this kind require sensors that are miniaturised and cost-effective.

Batteryless wireless transmitter modules - 300 meters range and absolutely maintenance free EnOcean has developed a wireless sensor technology that detects control commands or measurement data without any external power source or batteries in the sensor unit.

Embedded EnOcean radios transmit some 300 meters in a free field, the length of three soccer fields. A wireless sensor is operated by the smallest amount of ambient energy. About 50 microjoules per action are sufficient, comparable to lifting 1 gram by 5 mm. Pressing the button of a TV remote control takes a multiple of this. A tiny magnet and coil system produces an electric voltage from finger pressure, for example, similar to the way power is generated by a dynamo for a bicycle light.

Vibration can be converted into electric energy by using piezoelectric crystals. When the crystal is flexed, energy is generated. Small solar cells, like those in calculators, can also power a wireless sensor from EnOcean. A small energy accumulator (Goldcap), recharged during just one or two hours of light, sustains the operation overnight.

A thermal converter, currently under development, makes use of temperature differences to generate voltage.Three to four degrees are sufficient for transmission, less than the difference in temperature between the air in a room and the surface of warm radiators or machine parts. These are just a few examples of highly efficient, micro energy converters already marketed by EnOcean or in the process of development. These switches are actuated based on the kinetic energy of a human being and therefore provide a virtual lifelong wa

Wireless switches are now gaining gradual popularity over the hardwired solutions. Though expensive they provide an array of advantages over the conventional switches which are beseiged with a plethora of issues ranging from short circuits, flare ups, failed mechanisms, lengthy installation uptime and ofcourse increased cabling costs. Western Countries are gradually seeing the benefits of wireless switches which have now manifested themselves in wide ranging applications.

Main Advantages

Energy savings

Flexibility of the applications

Time-savings

Maintenance-free

Ecological compatibility

Reduced fire risk and inductive fields

Cost-savings

No Battery Disposal problems

These Wireless Switches are wireless transmitters connected on the USB port of the PC and are used for communication with a receiver using radio frequency. The transmitters can be placed at any distance upto 30 meters and connected to the loads intended to be controlled. The software is pre-loaded on the PC to drive the wireless transmitter.

Typically, these transmitters can be operated manually or automatically using a screen saver. When the screen saver is activated, the connected loads will be turned off automatically. Some users prefer to turn off the loads only when the PC is powered off. The device can be used in individual cabins or open plan offices where there are individual lighting fixtures for each occupant and it becomes difficult to designate a motion sensor for each occupant.

In the event, airconditioning loads need to be controlled, a contactor or a relay needs to be installed. A bypass switch can also be incorporated in the circuit for bypassing the device.
