How to use

Place the thermo-hygrometer on a stable, flat surface away from direct sunlight, heaters, radiators or drafts to obtain representative indoor measurements. Insert batteries according to the polarity markings, switch the unit on if a power button is provided, and allow several minutes for the sensor to stabilize before taking readings. Check the display periodically to assess changes in temperature and relative humidity; relocate the device if you need to measure conditions in another room.

Usage recommendations

For reliable monitoring, keep the WS9455 in a central location in the room at approximately one to two meters above the floor and away from windows or heat sources. For plant care, position the device near the plant canopy but not in direct contact with soil or water. Replace batteries promptly when low-power indicators appear to maintain continuous measurements.
