FCC ID: PEQAJ26090807 Technical Description of the Circuit: The circuit is a RF thermometer & hygrometer transmitter part, the MCU TM8712 will measure the temperature & relative humidity and code the data. Afterward, the data is transferred to the RF circuit by the IC PT4450 which includes a SAW oscillator 434MHz. One-shot circuit every 3 minutes when the data pin output HIGH level to the oscillator, the oscillator is turned on and output 434MHz RF signal, when the data pin output LOW level to the oscillator, the oscillator is turned off, and this ON & OFF process modulate the code data into 434MHz with ON OFF KEYING.. L4, C8, L3, C7, L2 and C2 for antenna matching network.
