NiceRF SA809 Walkie Talkie Control Wireless Switch Module

SA809-Rx consists of walkie talkie and DTMF decoder, it works with a walkie talkie to succeed long-range wireless control. Any walkie talkie with DTMF function in the market can be used as a transmitter. For example, the GP338 of Motorola. When SA809-RX receives the signal of the transmitter, it will decode and compare with the password preset before. The high current MOSFET will be driven to output if the input signal is verified. SA809-RX is very high security with 1—10 digital password and 400—480MHz frequency channel. All the parameters can be set free with our PC software. It can achieve 5—8Km easily with higher output power walkie talkie, and widely used in the application of industrial control, smart home, etc.

Electrical characteristics

Functional description:

When powering on, it will enter into the Timeout status(Default 20 minutes, this timeout can be set as 0 –30minutes ),after time out, it will switch into DTMF receiving mode automatically. In this mode, if correct passwords are received, the output with Mosfet will output 3 seconds pulse( high level with 3s then low level ). SA809-RX has the sensitivity up to -124dBm and can achieve 8km range with normal walkie talkie with DTMF function. SA809-RX uses 0.5PPM TCXO crystal, 12.5KHz narrowband, industrial design, all the features make long time working stably in varies temperature environment. The frequency, password, time for a timeout can be set and stored in the EEPROM, which will keep unchanged even powered off.
