The EUT senses the UV index and then transmits this information to the main unit. A transmitter transmits signal for every 73 seconds, and it activated automatically shall cease transmission within 2 seconds after activation. Hence it operates 50 times per hour. FCC ID NMTUVN128-01 Model Product description UVN128 Remote UV Sensor UVR128 Remote UV Sensor The model UVN128 and UVR128 are same in circuit and PCB design, the difference between them is that UVR128 has LCD display and UVN128 is using LED indicator. Hence, the representative model UVN128 was chosen to perform all testing. Circuit Description The MCU power on the UV sensor circuit, the UV sensor will sense the UV strength and convert to energy, and the photo transistor will biased by this energy, and the output voltage will input to a voltage comparator, then give out an analog voltage, the voltage will feed to the MCU analog port, MCU will based on the voltage to calculate the UV strength by internal A/D converter, then display on the LCD and transmit the data to receiver unit through 433MHz. Ratings and System Details Transmitter Operated Frequency : 433.92 MHz Frequency deviation of Crystal : ± 75KHz Number of channels : 1 Type of antenna : Integral antenna Power supply : Battery operated 3.0V Ports : none Protection Class : III Equipment Class : B www.tuv.com Test Report No.: 14008707 002 Date: 12.05.2005 Page 7 of 13 Independent Operation Modes The basic operation modes are: - Automatically detect UV and transmit signal. - Reset.
