It is an outside temperature transmitter for a Sharp Wall Clock.
Apparently not. Seehttp://www.wpc.dot.gov.in/faq.asp#3What are the license- free bands?433 MHz is not listed there.
Remote control employs a frequency modulation (FM) radio frequency of 433 MHz transmission that has a strength range of 400 mt outdoors or 200 meters indoors [ through a wall ] to operate any electronic /electric relay driven gadget through a radio frequency decoder.433 MHz frequency can be produced by a small (size of a postage stamp) simple 4 bit chip that has no complicated circuit and better than complex inconvenient ones for higher range. 433 MHz frequency modulation radio waves are best suited for short range applications produced from compact micro circuit and therefore useful for short range use
That is the frequency of the G Sharp/A flat two octaves below middle C (great octave).
It communicates with the Control Panel using the 345 MHz wireless frequency.
FET's improve the switching frequency from KHZ to MHZ.. FET can be used as temperature sensor.. and mosfet is used as a switch..
he rating for RIMM memory is based on the maximum theoretical bandwidth (in MHz) and included speed ratings of 800 MHz, 1066 MHz, 1200 MHz, 1333 MHz, and 1600 MHz.
MHz. 1000 MHz = 1 GHz.
