The wireless transmitter module adopts ASK mode modulation to reduce power consumption. When the data signal stops, the emission current will be zero. The data signal and the DF transmitter module end can be connected by resistors or capacitors, otherwise the DF transmitter module will not work normally.The data level should be close to the actual operating voltage of the DF data module for higher modulation.

wireless transmitter receiver application.

Wireless transmitter module: The four-channel remote control module does not have a battery and four transmitter buttons. The antenna also becomes a flexible cable, which further reduces the size and facilitates a wireless alarm or remote control system with a single-chip microcomputer or other devices. For example, the combination of a magnetic switch and a magnetic switch can be changed. Into the wireless door magnet, and the human body pyroelectric module can be turned into a wireless human body sensor, and the combination of the single-chip microcomputer can use the powerful and flexible control function of the single-chip microcomputer to issue the transmitting front end of different address codes and control codes to form a point-to-multipoint remote control system.

The antenna is made of soft wire or other hard metal with a length of 23 cm. The length should not be too long or too short, otherwise it will affect the receiving distance. If using a flexible wire, use it straight and try not to get close to metal objects. The module’s operating temperature is -10 ° C ~ +50 ° C, characterized by high power, small volume, medium distance, no need for an external encoder.

The wireless transmitter receiver can be used in any field.

The 315m super-regenerative wireless transmitter module and receiver module only modulate the data signal on the 315M carrier and detect the data signal from the 315M carrier. The SC2262 and SC2272 can be programmed and decoded without using a single-chip microcomputer. The single-chip microcomputer can eliminate the need for editing and decoding circuits. The MCU can completely complete the encoding and decoding function.
