This is a micro controller based two way radio transceiver to control the remote device on a 0 – 10v DC control voltage .
The transceiver transmit and receives appropriate control signals at 433.9MHz. On receiving the control signal ,if the zone address matches with that particular RF cartridge the conformation of correct signal is indicated by turning ‘ON’ an LED and simultaneously the requested control is executed and it retransmits the acknowledge back. If the zone address does not matches with that particular RF cartridge, then it will act as “REPEATER” to route that zone address and level.

These are switching devices that respond to the presence and absence of people in the sensor's field of view. The system consists of a movement detector, an electronic control unit, and a controllable switch ( RF Transmitter ) . The movement detector senses movement and sends the appropriate signal to the control unit. The control unit then processes the input signal to RF transmitter to transmit signal at frequency 433.92MHz RF Cartridge fixed with electronic ballast receives signals and converts as analog signal which controls electronic ballast of lamps.

The movement sensor has been refined so that it responds not only to the presence of occupants, but also to the absence of occupants in the space. The technology have centered on reducing costs, increasing control intelligence, improving ability to detect minor movement, and increasing adjustment capabilities. Ultrasonic occupant sensors activate a quartz crystal that emits ultrasonic waves throughout space. The unit then senses the frequency of the reflected waves. If
there is movement, the reflected wave's frequency will shift slightly (Doppler effect). Ultrasonic sensors operate at frequencies that are above human sensitivity (20 kHz). Typical operating frequencies are 25, 30, and 40 kHz. The ultrasonic sound waves cover the entire area in a continuous fashion -- there are no blind spots or gaps in the coverage pattern. For this reason ultrasonic sensors are somewhat more sensitive to movement. For example, hand movement can be detected at a distance of about 20 feet, arm and full body movement can be detected out to over 25 feet. (The sensitivity range of different products will vary significantly.)

The lighting system consists of mainly two components. The transmitter and the receiver sections. The receiver section consists of RF receiver cartridges, which are connected to the dimmable ballast. These cartridges have address ranging from 1 to 250.This gives them a unique identity and enables them to be zoned i.e. a group of lights can be configured to have the same address (zone). This enables the light levels in a section to be set to the desired level by the user using transmitters.

The RF transmitters enable the user to communicate with the RF receivers to set
the desired light level. The levels range from 1 to 6 with level 1 being off and level 9 being full bright. The user selects the desired zone and the level in the transmitter to control the lights in a particular section.

FUNCTIONS :
Depending upon the light sensed by the antenna in the Daylight Harvester, It compares it with the Zone and light level set by the user.

Depending on the variation between these two parameters, the day light harvester transmits RF signal to the Dimmable Lighting System. (Either Dimming or Full Bright or ON / OFF)

The RF cartridge, fitted with dimmable ballast, receives the RF signal from the Transmitter and performs the required task of either Dimming or Full Bright or ON / OFF.
 

The Dimmable lighting system consists of mainly two parts . One is transmitter and another one is receiver section. The receiver section consists of RF receiver cartridge, which is connected to the dimmable ballast. This cartridge has address ranging from 000 to 255. This gives an unique identity and enables RF Cartridge to be zoned i.e. a group of lights can be configured to have the same address (zone). This enables the light levels in a section to be set to the desired level by the user using Hand held trans receivers . The RF transmitters enables the user to communicate with the RF receivers to set the desired light level. The levels range from 1 to 9 with level 1 being off and level 9 being full bright. The user selects the desired zone and the level in the transmitter to control the lights in a particular section. The Two Way Handheld Transmitter is a remote based light controlling unit. The unit consists of RF transmitter.

Select the zone and the level that has to be controlled by the transmitter to provide the user with the required light comfort. User can select the zone and levels from 1 to 9 from the software to control the light intensity in that zone.

Wireless Thermostat (A/c controller)

   The WIRELESS THERMOSTAT is a standalone device which can Maintain a constant room Temperature by switching ON and OFF the Cooling system according to the user set Temperature level. This Device can be configured to user comfort level sitting on his desk.

FUNCTIONS:
The system consists of a Temperature sensor, Amplifier, Analog to Digital converter and an MCU. The sensor senses the present Ambient Temperature and generates a corresponding analog signal which is amplified and fed to a Analog to Digital Converter. The Digital data generated is processed by the MCU to determine the ON or OFF state of the Air conditioner based on the User set Ambient Temperature Level.
