Outdoor sensor SENCOR SWSTH5800 — wireless weather sensor for temperature and humidity monitoring

Outdoor sensor SENCOR SWSTH5800 — wireless weather sensor for temperature and humidity monitoring is a compact, battery-powered transmitter intended to provide outdoor temperature and humidity readings to compatible SENCOR weather displays. The unit measures ambient conditions and sends data wirelessly so you can monitor external climate from inside the home, garden shed, balcony or a small greenhouse. The sensor housing is designed for outdoor use and supports a wide operating temperature range for year-round monitoring.

Advantages

The sensor offers wireless transmission at 433.92 MHz with a maximum range up to 100 metres under open-line conditions, and supports up to three selectable channels to avoid interference when several sensors are used. It operates from two AA 1.5 V batteries for convenient, widely available power, and its compact dimensions and low weight make installation and repositioning simple. Rated to work in temperatures from −40°C to 70°C and humidity up to 99%, the device is suitable for continuous outdoor monitoring.

Suitable for

• Remote home climate monitoring (paired with compatible SENCOR display units)
• Garden and balcony temperature and humidity checks
• Small greenhouse environmental monitoring
• Seasonal outdoor data collection for hobby weather stations

How to use

Install two AA 1.5 V batteries into the sensor following the polarity markings, then select a channel if multiple sensors are used to prevent signal overlap. Place the sensor outdoors in a sheltered, ventilated location away from direct water exposure and strong sunlight for representative readings. Ensure the sensor is within the RF range of the compatible SENCOR weather display and follow the display unit’s pairing or synchronization procedure to receive temperature and humidity data.

Usage recommendations

For reliable readings and extended battery life, mount the sensor out of direct rain and away from heat sources such as vents or reflective surfaces. Replace batteries promptly when low battery indication appears on the paired display. If signal problems occur, try relocating the sensor or check for obstacles between the sensor and receiver; using a different channel can reduce interference when multiple transmitters are operating nearby.
