The combination of noti5x core and a wireless transmitter is a cost-effective way to build a wireless doorbell.
High cost-effectiveness
No need to spend extra money on purchasing expensive wireless doorbell core components, such as receivers. You only need to purchase an extra transmitter and pair it with noti5x core to form a wireless doorbell.
The transmitter can be selected as either a passive transmitter or an active transmitter. Easy to install thanks to wireless transmission.
Passive transmitters have a shorter transmission distance, but they are wirelessly powered and can be used continuously. Active transmitters, on the other hand, can transmit over longer distances but may require battery replacement after a year (depending on usage frequency).
