Outdoor temperature and humidity sensor HAMA TS39H freestanding wireless with built-in display, AA battery

HAMA TS39H is a freestanding wireless outdoor temperature and humidity sensor with a built-in display. The compact unit is designed for outdoor placement and transmits measured temperature and relative humidity to compatible indoor receivers or weather stations. Powered by a single AA (Mignon) battery, the TS39H provides local readout on its integrated display while also supplying remote data for home comfort monitoring, gardening decisions, and basic weather observation.

Advantages

The sensor combines a visible integrated display with wireless transmission, allowing users to view current outdoor temperature and humidity directly on the unit and send measurements to a paired indoor device. Battery operation simplifies installation without the need for wiring, and the freestanding design makes placement flexible on patios, balconies, or sheltered outdoor areas. The device is suitable for straightforward monitoring tasks where clear, local readout and remote data forwarding are required.

How to use

Place the TS39H sensor in a sheltered outdoor location away from direct sunlight and heavy precipitation to ensure accurate temperature and humidity readings. Install an AA battery according to the polarity markings, then position the unit on a stable surface or in a protected spot. If using with a compatible indoor receiver or weather station, follow the receiver’s pairing procedure to register the sensor so that measurements appear on the indoor display. Read the current outdoor values directly on the built-in display or consult the paired indoor device for consolidated data.

Recommendations

For reliable readings and longer battery life, avoid placing the sensor in direct sun, exposed to driving rain, or near heat sources. Use the device in sheltered outdoor areas and replace the AA battery when the local display or paired receiver indicates low power. Verify compatibility with the intended indoor receiver or weather station before installation.
