## Description

**Introduction****Note:** This kit includes a [Gravity: Digital Wireless Transmit Switch (433MHz)](https://core-electronics.com.au/gravity-digital-wireless-transmit-switch-433mhz.html) and a [Gravity: Digital Wireless Receive Switch (433MHz).](https://core-electronics.com.au/gravity-digital-wireless-receive-switch-433mhz.html)

The transmitter module and the receiver module each ship with 1 Gravity: digital sensor cable by default. If you need more, please click [here ](https://core-electronics.com.au/gravity-4pin-iic-i2c-uart-sensor-cable-10pcs.html)to purchase separately.

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

When building a project that needs to transmit some 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...

This Gravity: Digital Wireless Switch might be just what you need! **Based on 433Mhz RF communication technology, the module includes a transmitter and receiver and features the advantages of simple operation, strong penetration, and ultra-low standby power consumption.** It is able to transmit digital signals and is compatible with any controller that can read and write digital signals. These modules are used on a wide variety of applications that require wireless control, such as, remote control, wireless doorbell, wireless signal transmission, upgrading wired buttons to wireless buttons, etc.
