Operational Description

Operational description of RX Main unit 1. The Jumbo thermo clock main unit is MCU based LCD clock. 2. U1 MCU is clocked by a 32.768KHz crystal. 3. Battery low detection circuitry de tects battery low level of battery. 4. Thermo sensor is connected to MCU to measure the indoor temperature. 5. Buzzer circuitry is the output stage for alarm and keystone. 6. RCC RX circuitry is a receiver to captu re and amplify the RCC signal. A formed time data is fed to MCU every 1 hour. 7. 433MHz RX circuitry is RF receiver to receive the outdoor temperature signa l form the transmitter. Operational description of TX : 1. MCU generates a sequenced c ode to fed the RF transmitter. 2. Battery low detection circuitry de tects battery low level of battery. 3. A SAW resonator works in 433MHZ TX transmitter to transmit the outdoor temperatur e signal to main unit. 4. Thermo sensor is connected to MCU to detector the outdoor temperature.
