H3V3E-H34S 315MHz Wireless Receiver Transmitter Module Set

The H3V3E-H34S is a matched 315MHz ASK receiver and transmitter module set designed for reliable short-range wireless control and data transmission. The H3V3E receiver uses a superheterodyne architecture with a high-performance RF integrated chip and a high-Q dielectric resonator for frequency stabilization, delivering -102dBm sensitivity and a reception bandwidth of 2MHz. It operates from a wide 2.7V to 5.3V supply, draws only 280µA typical current, and supports data rates up to 4.8kbps, making it suitable for battery-powered and low-energy designs. The H34S transmitter is a compact, tuner-free ASK module that pairs directly with the receiver, and the complete 315MHz receiver transmitter module set achieves a line-of-sight range of approximately 120 meters. Its ultra-small receiver footprint of 18mm × 12mm × 2.1mm allows integration into space-constrained enclosures, while the built-in automatic temperature compensation circuit maintains stable performance across a -45°C to +85°C operating range. This ASK RF module pair is widely used in anti-theft doors, wireless switches, security alarms, and IoT endpoints that require a simple, low-cost wireless link.

Application

1. Anti-theft doors, access control, and gate or garage door remote systems.
2. Security alarms and wireless switches for lighting and household appliances.
3. IoT endpoints including remote sensors, actuators, and data transmission nodes.
4. Industrial remote switching and simple wireless control tasks.
5. Battery-powered remote controls where low current draw and wide supply range are essential.
