{"title":"Gravity: Digital Wireless Receive Switch (433MHz)","handle":"gravity-digital-wireless-receive-switch-433mhz","url":"/products/gravity-digital-wireless-receive-switch-433mhz","description":"When building a project that needs to transmit some simple signals wirelessly, have you been bothered by the 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 Swtich 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 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. Note: The transmitter module and the receiver module each ship with 1 Gravity: digital sensor cable by default. If you need more, please purchase separately (FIT0011)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 itBoard OverviewFeatures15 button states of the transmitterPairing function for the receiver Support one-transmit and multiple-receiveSupport one-receive and multiple-transmitMultiple working modes: inching, latching, self-locking, and interlockingApplicationsRemote controlWireless doorbellWireless signal transmissionUpgrading wired buttons to wireless buttons, SpecificationWorking voltage: 3.3~5.0V DCStable transmission distance: 15M indoorTransmitter emission current: 10mA@5VTransmitter standby current: <10uA@5VReceiver emission current: 6mA@5VReceiver standby current: 3mA@5VInput signal: digitalNumber of interfaces: 4Working frequency: 433MhzTransmitter size: 47x32mmReceiver size :37x32mmMounting hole size: inner diameter 3.1mm/outer diameter 6mmDocumentsProduct wikiSchematicDimensionsShipping ListGravity: Digital Wireless Switch\tx1 Gravity: Digital Sensor Cable\tx1","vendor":"DFRobot","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":2601,"title":"Default Title","sku":"DF-TEL0142","price":13.41,"on_sale":false,"in_stock":true,"available_quantity":47,"option1":"Default Title"}]}
