YoLink Outdoor Contact Sensor: Did You Know?
Looks like Clark Kent, but this is truly a Super Sensor:
Outdoor-rated waterproof enclosure for use indoors and out. Comes with magnetic contacts suitable for most doors and gates. Additionally, the contacts may be removed, to connect the leads to high-security commercial contacts, or to a relay or other "dry contact" devices and equipment, to integrate like a superhero!
