100 Meters RF Wireless Transmitter Module Fixed Code Remote Control Board TB-02 (Model 0021035)

Feature: Model No.: 0021035 (TB-02) Size: 31mm x 23mm x 7mm Working Voltage: DC3~12V Working Current: 15~45mA RF Sensitivity: -103dBm Transmitting Distance: 100m / 300ft (in open field) Transmitting Power: 15dBm (10mW) Modulation Method: Amplitude modulation (ASK or OOK) Encoding Mode: Fixed code by Soldering Working Temperature: -20°C ~ +70°C Frequency: 433.92 MHz Oscillation resistor / Timing resistor: We can offer 1.2M, 1.5M, 1.8M, 2.2M, 3.3M or 4.7M, you can choose one. Reliable Control: Use an 8-bit code (Encoding). Stable performance; using SAW (surface acoustic wave) to stabilize frequency Wide working voltage range, large transmitting power and long transmission distance Application: Used for wireless calling system, burglar alarm, wireless data transmission, auto data collection system and so on. Applied to all fixed code receivers with 1, 2, 3, 4, 6, 8, 10, 12, 15 channels Notes: The transmitting frequency, encoding mode and timing resister should be compatible with the receiver. It is best to use the antenna of 1/4 wavelength, for antenna has a great impact on receiving effect of the module; normally using 50Ω single core cable. For frequency 433MHz, the length of antenna is about 17cm. The position of antenna also affects the receiving effect of the module. When installing the antenna should be extended as much as possible and be away from the shield and the place in high pressure and interference.
