When building a project that needs to transmit simple signals wirelessly, have you been bothered by any of the following problems: Bluetooth's cumbersome AT command configuration and high cost, Wifi's signal limitations and high power consumption, IR emission angle and inability to penetrate through the walls?
If so, the Gravity: Digital Wireless Receive Switch might be just what you need!
Based on 433Mhz RF communication technology, the module includes a receiver and features the advantages of simple operation and ultra-low standby power consumption. It's able to receive digital signals and is compatible with any controller that can read and write digital signals (you will need a transmitter to send signals to this device).
These modules are used on a wide variety of applications that require wireless control, such as remote control, wireless doorbells, wireless signal transmission, upgrading wired buttons to wireless buttons and more.
Note: 433MHz is a certification-free frequency band in most parts of the world, please pay attention to local policies and laws and regulations when using it.
