H-Tronic HT8Splus 8-Channel Wireless Transmitter Module 868.35/869.05/869.55 MHz, 200 m Range, 3 V 1618190

Reliable wireless control over distances up to 200 meters in open field remains a challenge for many automation projects. The H-Tronic HT8Splus transmitter module addresses this by providing eight independent digital input channels on three selectable frequencies, ensuring robust signal transmission with low power consumption.

Who is it for

This transmitter is intended for integrators and advanced hobbyists building custom remote control systems, alarm signaling, or industrial telemetry. It pairs with the H-Tronic HT8Rplus receiver series and operates from a single CR2032 coin cell, making it suitable for battery-powered sensor nodes or handheld controllers.

Main features

• 8 digital input channels for versatile switching or status reporting
• Tri-frequency operation: 868.35 MHz, 869.05 MHz, 869.55 MHz
• FSK modulation with 9.6 kbit/s data rate for reliable data transfer
• Maximum transmission range of 200 m in open field
• Ultra-low standby current below 1 µA, extending battery life
• Integrated PCB antenna simplifies installation
• Wide operating temperature range from -20 °C to +70 °C

Specifications

• Operating voltage: 3 V DC
• Power supply: 1x CR2032 button cell (not included)
• Transmit current consumption: approx. 10 mA
• Maximum output power: 10 mW (+10 dBm)
• Interface: pin headers for digital inputs
• Compatibility: H-Tronic HT8Rplus receiver series

Tips

For best range, mount the transmitter away from large metal surfaces and use a fresh CR2032 cell. When integrating with the HT8Rplus receiver, ensure both units are set to the same frequency channel. The low standby current allows the transmitter to remain connected to a sensor for months on a single battery.
