Tel 2764 7873 Fax 2765 6620 Cable IDTRAYMOND Telex 36567-IDTHK HX Technical Description of WTGR800 The WTGR800 is outdoor integrated wind sensor with wind speed, wind direction, temperature and humidity. It is operated by 4 pieces of size AA batteries (DC 6V). The voltage suppied to MCU is regulated to DC1.5V, so that the performance of the product can be guaranteed before the battery voltage drops to 1.5V. WTGR800 is a remote transmitter. It converts wake up measurement into OOK signal format and tramsits through the RF channel of 433.92MHz. It is consisted of 2 parts: Control part and transmitter part. The MCU outputs the digital data, then this data will be modulated into the Colipittis oscillator, where the SAW XT1 are used to adjust the operating frequency to 433.92MHz. The transistir Q3, with its fT greater than 6GHz, provide a good frequency response to the oscillator circiutry.
