TFA rain transmitter TFA.me 30.3903.02 ID-A1 white — wireless rain sensor for weather stations

The TFA rain transmitter TFA.me 30.3903.02 ID-A1 white is a wireless rain sensor designed to detect precipitation and relay measurements to compatible weather stations. Compact and weather-resistant, the transmitter measures rainfall events and communicates data wirelessly to a base unit for monitoring and logging. The device is intended for outdoor placement where it can reliably record onset, duration and intensity of rain to support automated weather logging and routine outdoor decision-making.

Advantages

The transmitter provides wireless transmission of rain measurements, allowing integration with compatible weather stations without the need for wired connections. Its design prioritizes outdoor durability and simple installation, while delivering timely precipitation detection suitable for garden, home or small-scale agricultural use. The white housing aids visibility and blends with common outdoor mounting locations.

Suitable for

• Home and garden weather monitoring
• Irrigation scheduling and rain-dependent automation
• Small-scale agricultural or hobby farming use
• Outdoor activity planning and sheltering sensitive equipment

Key specifications

• Type: wireless rain transmitter compatible with selected weather station base units
• Detection: precipitation detection for rainfall events and intensity monitoring
• Housing: weather-resistant outdoor enclosure in white
• Mounting: designed for outdoor mounting on posts, brackets or flat surfaces
• Power: battery-operated (user-replaceable batteries)
• Transmission: wireless signal suitable for short to medium outdoor distances to a paired base unit

How to use

Install the transmitter outdoors in a clear, open location away from obstructions such as overhanging roofs or dense foliage that could block rainfall. Secure the unit to a stable mount following manufacturer mounting guidance and insert fresh batteries before pairing. Use the compatible weather station base unit to complete wireless pairing and configure the system to receive and display rain data. Periodically check battery status and the housing for debris or blockages that could affect precipitation detection.

Usage recommendations

Place the sensor at a standard mounting height and in an area exposed to open sky for accurate rainfall measurement. Avoid locations where runoff from roofs or nearby structures can enter the sensor area. Regularly clean the sensor surface and ensure batteries are replaced according to the base unit’s low-battery indications to maintain reliable data transmission and measurement accuracy.
