However, we often encounter problems when using the battery, for instance, it is troublesome to replace the battery, batteries are easy to corrode in a humid environment, or the waste batteries may cause serious environmental pollution. Do you know that wireless remote control can actually work without batteries!\nThis self-powered wireless switch from DFRobot can send signals wirelessly without installing a battery. The switch is composed of a micro-generator and a 433Mhz radio frequency circuit. Based on the principle of electromagnetic induction, the micro generator converts the kinetic energy of the press into electrical energy that will be rectified and stored by the RF circuit later, by which a signal can be transmitted wirelessly. It is suitable as a maintenance-free switch for long-term monitoring of changes in the state of pressing, collision, etc., such as making wireless doorbells, pagers, food ordering devices, wall switches, etc.A receiver is required when using this product. It is recommended to use it with our official Gravity: Digital Wireless Switch Receiver (433MHz), or other receivers that support EV1527 decoding format and 10Kbps decoding rate.Connection\nFeatures\nNo battery needed, maintenance-freeWireless signal, wiring-freeRF signal, strong penetrationOnboard 4-position DIP switch, adjustable 15 states1 million sets of random address codesThe lifetime of 100,000 presses\nApplications\nWireless doorbellsPagersFood ordering devicesWall switches\nSpecification\nWorking Frequency: 433MhzTransmission Rate: 10kbpsEncoding Format: EV1527Output Power: 13dBmModulation Method: OOKPower Generation Energy: 600uJModule Size: 47x25x11mm(L*W*H)/1.85x0.98x0.43”Press Down Force: Typical 1800gAction Method: Automatically rebound after pressing downAction Distance: 2.6mm (endpoint)Press Frequency: no more than 4 times per second, continuously rapid press will cause energy accumulation that cannot be consumed in time, and eventually burn the chipStable Transmission Distance: Indoor 40MDistance Test Condition: Straighten the wire antenna of the transmitting module, and for the receiving module, use [Gravity: Digital wireless switch receiver(433MHz)]\nDocuments\nProduct wiki\nShipping List\nSelf-powered Wireless Switch x1","vendor":"DFRobot","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":2162,"title":"Default Title","sku":"DF-TEL0146","price":15.06,"on_sale":false,"in_stock":true,"available_quantity":147,"option1":"Default Title"}]}
