UU7DCRX2Receiver for Outdoor Sensor

FX5500-RX Operational Description This is a multifunctional LCD display radio controlled clock, and the thermometer for house hold application. The unit shows the real time clock, also capable to receive WWVB radio controlled clock signal then self adjust the time date according to WWVB clock signal. This device provides daily alarm time. The unit uses 3 pcs of 1.5V battery in-series connection through out regulator give 3V supply and low power consumption design. The indoor thermometer provides very accurate local air exactitude temperature. RF remote sensor receiver capable handles 3 channel of remote temperature&humidity Sensor from outside. Temperature alert function is user to preset desired temperature alarm level. The Humidity sensor provides the data of humidity to display. The unit shows the moon phase. The pressure sensor provides the data of atmospheric pressure to display the weather forecast, the barometric pressure trend Bar chart and barometric pressure meter.

It operates at 433.920MHz and the oscillation of radio control is generated by a LRC circuit. The EUT is power by 3 x 1.5V AA size batteries or AC 120V to DC 4.5 adaptor. There are five function keys and two LCD display in the EUT. When it switch on and received the radio signal, it will display the outdoor (remote) temperature on LCD. The brief circuit description is listed as follows: - TM87062(B) and associated circuit act as Microcontroller. - TM87062(A) and associated circuit act as Microcontroller. - X1 and X2 and associated circuit act as an oscillator for TM87062(A) and TM87062(B). - Q1, NJM022D and associated circuit act as receiver and amplifier. - RCC IC and associated circuit act as radio control clock controller.
