• Low-Power Means Longer Battery Life: Because of the low power consumption, YoLink Garage Door Sensor's batteries may last 5 years or more (depending on application and device usage/activity), on standard AAA Alkaline batteries (lithium batteries not required)!
• Wireless Range: Utilizing LoRa technology, this system boasts the longest range on the market at 1/4 mile. Its extensive coverage makes it suitable for challenging areas like basements, outdoor spaces, sheds, garages, and remote buildings on your property.
