What to know before buying

Listing details to confirm

The listing gives conflicting temperature ranges and humidity ranges, and states both 60-second updates and a 30-second detection interval. Its stated accuracy is also formatted inconsistently, and the claimed 100 M/328 ft signal distance differs slightly from the 330-foot placement guidance. Confirm the desired measurement limits and operating details before relying on these figures. The main unit needs three AAA batteries and each sensor needs two. The display backlight turns off after 10 seconds, and sensor reconnection may require holding the CH button.
