Temperature sensor SATEL AXD-200 — indoor temp and humidity, CR123A battery, compact 20×102×23 mm

The SATEL AXD-200 is a compact indoor temperature and humidity sensor designed for continuous climate monitoring in homes, offices and technical rooms. Its slim housing (20 × 102 × 23 mm) and white finish allow discreet placement on a shelf or flat surface. The device provides measured temperature and relative humidity data to support HVAC control, environmental monitoring and comfort management. It operates on a CR123A 3V battery and is rated to work reliably across a wide operating temperature range.

Advantages

The AXD-200 offers a compact form factor and simple freestanding installation without the need for external power wiring. Battery operation with a CR123A cell supports up to approximately two years of service under normal conditions, making the unit suitable for locations without mains access. The device combines temperature and humidity sensing in one sensor, enabling coordinated control of heating, ventilation and air conditioning systems or integration into building monitoring solutions. Its white enclosure and small footprint reduce visual impact in interior spaces.

Suitable for

• Residential climate monitoring in living rooms, bedrooms and hallways
• Office environment monitoring for comfort and equipment protection
• Technical rooms, storage areas and utility spaces where temperature and humidity tracking is required
• Use as an input for HVAC control or building automation systems

Key specifications

• Measured parameters: temperature and relative humidity
• Detection technology: wireless magnetic-compatible detection elements
• Operating temperature range: -10°C to +55°C
• Power supply: CR123A 3V battery
• Enclosure colour: white
• Dimensions: 20 × 102 × 23 mm (compact, freestanding form)

How to use

Place the AXD-200 on a stable, flat surface or mount it in a location where it can measure representative room conditions, away from direct heat sources, drafts and direct sunlight. Insert a fresh CR123A 3V battery following the polarity markings, then pair or register the sensor with the relevant SATEL control panel or compatible receiver according to the system instructions. Verify measured values through the connected control interface and allow the sensor a short stabilization period for accurate readings.

Usage recommendations

For reliable measurements, position the sensor at typical breathing or equipment height (about 1–1.5 m above floor level) and avoid enclosed cabinets or locations near heating vents. Replace the CR123A battery when low-battery indications appear in the control system, and perform periodic checks to ensure the sensor remains free of dust and obstructions that could affect humidity readings.
