The EUT senses the temperature and humidity level and then transmit this information to the associated weather station. A transmitter transmits signal for every 30.24 seconds, and the signal on period is about 0.143s. It activated automatically shall cease transmission within 5 seconds after activation. FCC ID: NMTTHX122NR-01 Models Product descriptions THR138, THR138R Water Resistant Remote Sensor with LCD Display THN138, THN138R Water Resistant Remote Sensor The models THN138, THN138R are identical in construction including PCB layout to the model THR138R, except the change in housing design and removed LCD display. 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 THR138R is the most complex and integrated, the model THR138R was chosen as a representative model for testing. Circuit Description THR138R is a remote thermometer sensor and transmit data by using 433.92MHz. After every time of thermometer 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 determinate 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. Capacitance C12, C13, C14 are employed to match the impedance of the antenna.
