“The CC1101 is TI’s ultra-low-power wireless transceiver chip that supports the sub-1 GHz frequency band and is mainly aimed at industrial, scientific and medical (ISM) and short-range wireless communication devices (SRD). The CC1101 provides extensive hardware support for packet processing, data buffering, burst transmission, Received Signal Strength Indication (RSSI), Clear Channel Assessment (CCA), Link Quality Indication (LQI), and Wake-on-Wireless (WOR). Supports multiple signal modulation modes (OOK/ASK, GFSK, 2-FSK, 4-FSK and MSK); supports data rates from 1.2kbps to 500kbps. The maximum transmit power is 10dBm.

1. Introduction of E07 series modules
The E07 series module is a wireless module with small volume and multiple packages designed and produced by Chengdu Ebyte Co., Ltd. based on the CC1101 chip. The default transmission power is 10mW; there are also modules with built-in PA, and the transmission power can reach 100mW. The module adopts SPI interface, integrated transceiver, can work in 433MHz, 868MHz, 915MHz mainstream ISM frequency band, supports low-power development, this series has been in stable mass production, and is suitable for a variety of application scenarios (especially hotel Electronic door locks) ).
2. Application of E07 series modules in smart door locks
The intelligent door lock is improved on the basis of the traditional mechanical lock, and the original mechanical unlocking method is improved to the intelligent identification method. These include biometric identification methods such as fingerprint unlocking and iris recognition; wireless keys, radio frequency cards, magnetic cards and other non-contact types. The following will illustrate the use of E07 series modules in smart door lock applications.
3. Conclusion
There are already many solutions for smart door locks. No matter what kind of communication method is used, we all hope that it has low cost, low power consumption, safety and stability, so we recommend the products of Chengdu Ebyte.
