Motion Sensor Light Bulbs 12W Dusk to Dawn PIR Built-In Motion Detector Smart Bulbs E26 Base A19 Indoor Outdoor LED Light Bulbs 3000K Warm White 1000 Lumens Security Night Lights 2 Pack by COOWOO

✅Built-in dusk to dawn sensor->This smart bulb will automatically turn to standby mode when the darkness is lower than 6lux, being ready to turn on when the motion detector is activated, and this happens at dusk or during night time when darkness falls. The bulb will switch to energy saving sleep mode in the daytime as the light intensity raises up to 6lux, under which circumstance bulb will not be turned on..

✅Infrared motion detector->With the smart infrared induction detecting model, human or animal movement in darkness will trigger the light on within the detection range and bulb turns off in about 30 seconds after you leave the area. The detection distance is around 16-20 feet given the certain installing height and other factors. This PIR motion sensor light bulb DO NOT work through glass or any lamp covers and must be installed downward..

✅Continuously picking up movement signal->The motion sensor keeps detecting human activities within the range, leaving the light on even if 30 seconds passes if you haven't left the area. Therefore the 30-second countdown will start from your very last movement. No one will be happy if the light suddenly turns off right?.

✅1000 lumens ultra brightness and pleasing warm white->Considering that you might need this smart bulb to be weight brighter than normal bulbs, it is settled to be 120W halogen equivalent while consumes only 12W of power, saving up to 90% off on lighting bills. And the 3000K warm white color is the best to eye protection, when bluish white light is like hospital operation room..

✅What's the most suitable place for using this good bulb->Actually there are too many places that can use this bulb, but our engineer indeed has suggested some: stairs, hall way, bathroom, storage room, garage, balcony, gate and so on. The higher you hang the bulb, the larger detection range it achieves as the highest could be 13 feet vertically..

Specification:
☛Wattage: 12W
☛Voltage: 120V
☛Base type: Standard E26
☛Material: Aluminum & PC
☛Working temperature: -10℃-35℃
☛Color rendering index: 80+
☛Detection angle: ≤120°
☛Detection distance: 16-20 feet
☛Shut down delay: 30 seconds
☛Package includes: 2 bulbs in one box

So what's new?
☆1000 lumens ultra brightness 120W Equivalent while consumes only 12W of power.
☆Reacts only to human or animal motion so it is smarter than ever.
☆Light off delay down to 30 seconds to meet our actual needs.
☆Continuous movement keeps the light always on.
☆16-20 feet super large theoretical detection distance.

Read this before ordering
☑This PIR motion sensor light bulb CAN NOT work through glass or any lamp covers, as the bulb top must be completely exposed.

☑Stay away from places where there is direct sunshine, air conditioner, dryer, heater or strong electromagnetic wave, so as to avoid interference.
☑If intend to use the bulb for outdoor fixtures, please find a way to protect it from water yet no blocking the sensor parts on the top of bulb.
☑Supports only normal switch and should always be turned to on position, and other switches like sound switch, touch switch or sensor switch DO NOT work with the motion sensor bulb.

Zircon Leak Alert WiFi - Smart Electronic Water Detector Alarm with Email, Audio and Visual Alerts - Battery Included

The Leak Alert WiFi smart water detector connects to Wi-Fi and immediately sends email alerts when even the slightest amount of moisture is detected.

Name each wifi water sensor with its location during set up and email alerts will direct you immediately to the source of the alarm! Loud 105 dB alarm and flashing SOS alert even when Wi-Fi isn't available.

Independent and hubless system allows an unlimited number of Leak Alert WiFi water detectors to be set up and running at any given time. Perfect for homes, schools, offices, hotels, property management, and more.

Continuously monitors for leaks around sinks, dishwashers, appliances, refrigerators, washing machines, sump pumps, water heaters, hot tubs, water filtration units, and more.

Fully automatic battery-powered operation - no wiring required for this smart water sensor. Like your smoke and carbon monoxide detectors, a low battery warning chirps an alarm when it is time to replace the 3V Lithium battery.

The Zircon Leak Alert WiFi smart water detector is a wifi water sensor and alarm that protects your property. This compact wifi leak detector allows for easy placement anywhere in any place that has potential for flooding or leaks such as near water heaters, sinks, dishwashers, sump pumps, and more. The Leak Alert WiFi is battery operated, wireless and fully automatic so no wiring or hub is required and all the limitations of hub-based wired products on the market are avoided. When moisture is detected, the wifi water detector will sound an 105 dB alarm, emit a visual warning by flashing a SOS, and will send an email alert via your Wi-Fi connection to up to five email addresses to warn you of the water leak. This could potentially save thousands of dollars in water damages. The Zircon Leak Alert WiFi eliminates the need for all the expensive accessory equipment by operating independently on a hub-less platform. Each unit operates independently of each other and can be individually named, allowing for an infinite number of units to be on guard protecting your space from water damage. Name each wifi water alarm during the set-up process (it is best to name each unit uniquely based on the location the device is utilized) and the emergency email will alert you of the exact location of the problem allowing for even faster intervention. Should a flood occur, the Leak Alert WiFi unit will float and continue to send out visual flashing alerts, an auditory alarm, and email notifications so it can be both seen and heard from a distance. Zircon designed this wifi water leak detector to chirp and send email notifications when the battery is running low and needs to be replaced. Each Leak Alert WiFi unit includes an easily installed standard 3V Lithium battery to keep your smart water leak sensor running at optimal performance. Just like your smoke detector, remember to check and replace your Leak Alert WiFi batteries every year. The Leak Alert WiFi is the perfect water detector for HOA, multi-unit, and multi-story property managements. It is also a great smarthome device to meet the needs of your property and protect your apartment, home or office. The Zircon Leak Alert WiFi allows you to save money and protect your entire property with one purchase.
