The EUT senses the temperature and humidity level and then transmit this information to the associated weather station. A transmitter transmits signal for every 41 seconds, and the signal on period is about 0.39s. It activated automatically shall cease transmission within 5 seconds after activation. Hence it operates around 88 times per hour. FCC ID: NMTTHX122NR-01 Model Product description THGR122N, THGR122NR Water Resistant Remote Sensor with LCD Display THGN122N, THGN122NR Water Resistant Remote Sensor THR122N, THR122NR Water Resistant Remote Sensor with LCD Display THN122N, THN122NR Water Resistant Remote Sensor The construction of models THGR122NR, THGN122NR, THR122NR, THN122NR are identical in main circuit and mechanical design, except with difference LCD display and temperature / humidity (or only temperature) function. For those models with suffix “R”, they are re-engineering models and are used for internal reference only. They are totally identical to the models without suffix “R”. For the above multiple models, due to the model THGR122N is the most complex and integrated, the model THGR122N was chosen as a representative model for testing. Circuit Description THGR122NR is a Remote thermo-hygro sensor and transmits data by using 433.92MHz. After every time of thermo-humid measurement, the data will be transfer to the receiver unit through 433.92MHz. It composes of a controller part and a transmitter part. The transmitter is basically a Colippttis oscillator, where C5, C6 and Y1 are used to determine the resonant frequency that is 433.92MHz. Transistor Q3 whose fT is greater than 6GHz, provides a good frequency response to the circuit. There is a filtering circuitry, use L1, that is used to suppress harmonics of the oscillator. Capacitances C12, C13, C14 are employed to match the impedance of the antenna. Ratings and System Details Transmitter Operated Frequency : 433.92 MHz 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.: 1401…
