1. The principle of roller shutter remote control from China manufacturer launch part
The launch part is generally divided into two types, namely the remote control and the launch module. The remote control and the remote control module are for the way of use. The roller shutter remote control from China manufacturer can be used independently as a whole machine. Wiring pile head; while the remote control module is used as a component in the circuit, and it is applied according to its pin definition. The advantage of using the remote control module is that it can be seamlessly connected with the application circuit, small size, low price, and make the best use of everything. But the user must really understand the circuit principle, otherwise it is still convenient to use the remote control.
2. The principle of roller shutter remote control from China manufacturer receiving part
Divided into super-heterodyne and super-regenerative receiving methods, the super-regenerative demodulation circuit is also called a super-regenerative detection circuit, which is actually a regenerative detection circuit working in the state of intermittent oscillation.
roller shutter remote control from China manufacturer reminds that since the carrier frequency is fixed, its circuit is simpler than that of a radio. The super-heterodyne receiver is stable, has high sensitivity and relatively good anti-interference ability; the super-regenerative receiver is small in size and cheap.
