1 Pack 315/433/868MHz Wireless Transmitter & Receiver Kit, EV1527 Encoder, 3V DC (Low Voltage Detection: 2.2±0.2V), Long Range up to 100m, for Home Security Alarm System

• 【Power & Efficiency】​ Operates at DC 3V, with a static current ≤1μA (ultra - low standby power) and working current ≤12mA. Under - voltage detection point is 2.2±0.2V to prevent unexpected power - off.
• 【Frequency & Range】​ Supports 433MHz frequencies. Achieves a transmission distance of ≥100m, ideal for long - range wireless applications (e.g., remote control, sensor systems).
• 【Temperature Resistance】​ Works stably in the temperature range of - 10℃ to 50℃, suitable for various environments (indoor, outdoor, or industrial scenarios).
• 【Compact Size】​ The transmitter measures 23×60×13mm, and the magnetic strip is 10.2×40.2×12.8mm. Its small size makes it easy to integrate into different devices or projects.
• 【Versatile Application】​ Perfect for DIY electronics, home automation, remote sensing, or any project requiring reliable wireless transmission with low power and long - range capabilities.
• 【Note】: This product requires use with an alarm kit and cannot be used independently. Any device on the market operating at the 433MHz frequencies compatible may be used.
• 【🛡Reliable Protection & Comprehensive Service】XNH possesses mature R&D and manufacturing expertise! Upon receiving your order, we provide a one-year quality warranty for your peace of mind. Should any queries arise, our expert support team is available for consultation, responding within 24 hours.
