The English name of wireless doorbell is wireless doorbell, also known as wireless remote doorbell or remote doorbell. Wireless doorbell is a kind of doorbell developed by civil wireless technology. The wireless doorbell does not need wiring, and the installation is simple and flexible.
But what makes people worry is that the ordinary wireless doorbell needs to use the battery. If the battery is not replaced in time, it will not ring!!!! Men's tickets, women's tickets, Baba's tickets, and Ma's little friends can't be heard.
However, geese, the wireless doorbell without the kinetic energy of the battery is the black technology that I want to tell you today! Let you never have to worry about changing the battery for the doorbell!
Kinetic energy wireless doorbell - the doorbell relies on the power generation technology by pressing the button to get rid of the battery.
Kinetic energy wireless doorbell is a self generated wireless doorbell. It does not need to connect to power supply equipment such as battery and power supply. It generates working energy by the mechanical action of the button.
Kinetic energy wireless doorbell not only solves the problem of flexibility in architectural design and decoration, but also solves the problem of traditional wireless doorbell requiring regular battery replacement and environmental pollution caused by batteries.
Therefore, kinetic energy wireless doorbell is a green electrical product with the most promotion and use value in the current energy-saving and emission reduction environment.
Composition of kinetic energy wireless doorbell system
Principle of kinetic energy wireless switch
Basic principle of kinetic energy switch: electromagnetic induction. The electromagnetic induction device is driven and electric energy is generated by the action of manually pushing, pulling and rotating the switch. The generated electric energy drives the functions of the back-end and the RF circuit to work.
Hoperf low power RF transceiver chip
Huapu cmt2150a is a low-power and high-performance ook modulation and transmission chip with integrated encoder. The chip supports 240 to 480 MHz wireless applications.
Cmt2150a supports the exclusive nextgenrf patented algorithm technology of Huapu. The encoder is integrated inside the chip, which can be compatible with 2 code type.
The chip supports up to seven definable switch interfaces in multi switch mode. At the same time, cmt2150a has extremely low power consumption, especially suitable for applications in low-power systems.
Huapu cmt2210a is a low-power, high-performance, independent running ook RF receiver, suitable for various 300-480 MHz wireless applications.
Cmt2210a supports the exclusive nextgenrf patented algorithm technology of Huapu. Cmt2210a is based on a fully integrated, low IF receiver architecture. This low if architecture effectively reduces the number of peripheral components required, thus reducing the application cost.
At the same time, cmt2210a has extremely low power consumption and is particularly suitable for applications in low-power systems.
Unique advantages of Huapu RF transceiver chip
■ the ui software can flexibly modify the frequency, power, speed and modulation mode without software programming, greatly shortening the R & D cycle and accelerating the speed of product marketing.
■ ensure 100% successful passing of CE and FCC safety certification in Europe and America, and sufficient margin of harmonic and blocking test parameters.
■ nano scale wafer process, which can be configured with the manufacturer's key arbitrarily, to prevent cracking and copying, and ensure the continuity of subsequent orders.
■ built in EEPROM (optional), supports millions of online modifications, can store ID codes and lock points, and saves MCU port lines.
■ the chip is pin to pin compatible, the software is unchanged, and only one chip can be replaced to realize any frequency point and any modulation mode.
