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.

We also stock the matching Gravity Transmit Switch module, and also a kit containing both modules together.

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.
