Key specifications
 Measured parameters: temperature, humidity
 Transmission: wireless radio between sensor and display
 Housing: compact, weather-resistant enclosure for outdoor use
 Mounting: includes brackets for wall or post installation
 Display: clear interface for current readings and basic history
How to use
Install the sensor outdoors using the supplied mounting brackets, choosing a location sheltered from direct sunlight and strong precipitation for representative measurements. Insert batteries into the sensor and the display according to the manufacturer’s markings, then pair the sensor with the display following the on-screen or manual instructions. Place the display indoors where it is easy to read; it will receive updates from the outdoor sensor automatically once paired. Periodically check battery status and clean the sensor housing to ensure unobstructed airflow for accurate readings.
Usage recommendations
For best accuracy, mount the sensor at typical ambient height (about 1.5–2 meters) away from heat sources and reflective surfaces. Replace batteries before levels are low to avoid gaps in data transmission, and perform occasional visual inspections to remove debris or insect nests that could affect sensor performance.
