Product Description

Description:
The CY21 is an ASK/OOK compatible super heterodyne wireless receiving module with high performance for ISM frequency band. With the adoption of European brand RF wireless data transferring/receiver chipsets, the module has advantages at high receiving sensitivity, small size and low cost. It solves the problem on space for the small-sized product. From wireless signal input to data output can be done without any electrical circuit. User only use extra simple data decode circuit can achieve wireless products development.
 

Features:

1. Frequency: 315MHz/433.92MHz (custom frequency is available);
2. High sensitivity -107dBm;
3. Supply voltage: 2.4V - 3.6V;
4. Low power consumption: 3V @ 315MHz, 3.7mA; 3V @ 433.92MHz, 4.9mA;
5. Data Rate: 2.4Kbps (Manchester Code)
6. Operating temperature: -20ºC ~ 70ºC, work normally even in the severe temperature environment;
7. Excellent inhibiting ability for local oscillator radiation: multiple receivers receive signals from one transmitter simultaneously without any mutual interference and influence on range;
8. Favorable selectivity and inhibiting ability for stray radiation; easy to pass CE/ FCC Certificates
9. Dimension: 30.5*10*5mm

Application

1. Remote door openers
2. Remote keyless entry
3. Wireless security systems
4. Remote control
5. Wireless door ring
6. Wireless data transmission
