Compact size design: Mini appearance, compact and lightweight, easy to integrate and install.</p><p>Product Introduction: <br/>This is an EV1527 transmitter module without a casing or buttons with decoding. It can be used to control a remote control with other devices, input DC3.7V-24V power to the transmitter module, that is, transmit signals. It is used for learning receivers and can be used in settings such as smoke detectors, alarms, buzzers, or other sensing devices, or other microcontrollers. The working voltage supports DC3.7V-24V with a wide voltage range of 3V/5V/6V/7.4V/9V/12V/16V/18V/24V. It is recommended to use DC3.7V-24V for battery power supply; The recommended voltage for power supply or battery is DC1.5V-24V, and the distance depends on the voltage and current. If it is a regulated power supply, 1.5V can support operation at a distance of several meters; If you use dry batteries for power supply, please use 12V/23A; 12V/27A; For 9V dry batteries, do not use 1.5V 2-cell dry batteries or 3V 1-cell button batteries. Dry batteries are recommended to start at 4.5V, and button batteries are recommended to start at 6V. The voltage and current are too low, and the distance will be very short (especially when using jog mode to maintain the transmission signal). If charging large capacity lithium batteries, batteries with voltages of 3.7V-12V can be selected.</p><p>Parameter: <br/>Working voltage: DC 3.7V-24V (wide voltage,Attention: Do not work at 24V for a long time, and it is strictly prohibited to use beyond 24V) <br/>Static working current: 0.1-0.6mA <br/>Maximum load: The load of 1A relay is less than 0.7A <br/>Receiving sensitivity: ≥- 110dBm <br/>Modulation method: ASK <br/>Encoding method: EV1527 (each transmitter&#x27;s code is independent and unique) <br/>Wireless frequency: 433mHz <br/>Working current: 5-30mA <br/>Transmission power: 20mW <br/>Launch distance: 20-300m <br/>Size: 21 * 11mm</p><p>Package Include: <br/>Combination 1: <br/>1X module</p><p>Combination 2: <br/>1X module <br/>1X remote control<br/><br/></p></div></div><p><br/></p>
