Weather station SENCOR SWS2300B — indoor/outdoor temperature and humidity monitoring, 1 wireless sensor, 433.92 MHz

The SENCOR SWS2300B is a compact weather station for monitoring indoor and outdoor temperature and humidity. It shows weather forecast icons, current time and date, frost alerts for the outdoor channel, and records of daily maximum and minimum values. The set includes one wireless outdoor sensor; the base unit can accept up to three sensors and can be placed on a desktop or mounted on a wall.

Advantages

The station presents both indoor and outdoor temperature and humidity with trend indicators and stores 24-hour max/min values. It supports selectable °C/°F temperature display and 12/24-hour time formats, offers alarm and snooze functions, and indicates low battery for the main unit and sensor. Wireless transmission works on 433.92 MHz with up to 80 m range in open area, and measured data from multiple outdoor sensors can be auto-scrolled on the main display.

Suitable for

• Home rooms where monitoring of indoor climate is needed (living room, bedroom, nursery)
• Garages, sheds or garden areas when paired with the outdoor sensor
• Small offices or workplaces requiring basic indoor/outdoor temperature and humidity readings

When it may not be suitable

This compact station is intended for general household and small-office use and does not provide professional meteorological precision or advanced logging beyond 24-hour min/max memory. The wireless transmission range (up to 80 m in open area) can be reduced by walls and other obstructions, so placement and building structure may limit outdoor sensor connectivity.

Key specifications

• Displayed measurements: indoor and outdoor temperature and relative humidity
• Temperature ranges: indoor −10°C to +50°C, outdoor −40°C to +60°C
• Humidity range: 1% to 99% RH
• Wireless sensor frequency: 433.92 MHz; transmission range up to 80 m in open area
• Supports up to 3 wireless outdoor sensors; 1 sensor included
• Time format: selectable 12/24 hours; temperature unit selectable °C/°F
• Power: main unit 2 × AAA 1.5 V (batteries not included); sensor 2 × AA 1.5 V (batteries not included)
• Dimensions (main unit): 65 × 100 × 24 mm; weight: 99 g

How to use

Install the batteries in the main unit and the outdoor sensor, place the sensor in the desired outdoor location within the transmission range, and position or mount the main unit indoors. The weather icons and trend arrows update automatically based on sensor data; use the settings to select preferred temperature unit and time format, set alarms if required, and view stored max/min records for the last 24 hours. If multiple sensors are used, the main display can auto-scroll measured values from all paired sensors.

What to consider before purchase

• Wireless transmission range may be reduced by walls, metal structures or interference—verify likely placement distances
• Batteries are not included; check required battery types (main unit: AAA, sensor: AA)
• The device provides household-level accuracy and 24 h max/min memory, not professional meteorological logging

Usage recommendations

Place the outdoor sensor under an overhang or in a ventilated, shaded area to avoid direct sun and precipitation. Keep the main unit away from heat sources and drafts for more accurate indoor readings, and test sensor pairing and signal strength after installation to confirm reliable communication.
