Home smart sensors allow you to monitor the essential and necessary inner workings of your home and connect to the internal home environment. Whether you need to detect leaking water or gas pipes, or you want to monitor motion for security purposes, you can find a versatile range of smart sensors and home security alarms to keep your home safe and secure. Consider essential factors and features such as function, wireless capabilities, smart hub integration and ease of installation when shopping for this equipment.

Door and Window Sensors Indicate When There is Entry Into a Home

Door and window sensors attach to a window or door frame for easy installation, and billowing drapes or wandering pets are less likely to trigger them. Close the sensor circuit when you shut the door or window. Opening it triggers an alert, so you can take action. Most door and window sensors operate via a central hub, and you can purchase them individually or in packs to cover multiple doors and windows. Upgrade your home security by integrating them with smart door locks and access accessories for improved insight, control and flexibility. Smart door locks notify the user when an intruder opens the door, and some use access codes or biometrics to distinguish coming or going motion.

Smart Motion Sensors Show Movement Within a Space or Rooms

Motion sensors detect movement within a space by using infrared technology, triggering an alert to indicate movement. They are highly customizable to cater to individual safety and security needs. Sensors come in different types and sizes, and most are compatible with other technology ecosystems. Choose a motion sensor with a simple plug-and-play setup for quick and convenient pairing with smart hub kits and other apps. Some home smart sensors can track movement over time and trigger additional action, such as switching the lights on automatically. They work well to monitor the movement of children or an elderly relative.

Temperature Humidity Sensors Help Regulate Your Indoor Climate

Temperature humidity sensors are smart home automation accessories that track and record changes in the temperature and humidity conditions of any space. The sensors use Bluetooth®, Wi-Fi® or a cellular network connection, and you can use them to monitor indoor climate conditions remotely at any point in time. Choose a precise and accurate temperature humidity sensor with a buzzer, or one that seamlessly relays email and text alerts when you are not physically present. Most sensors have apps through which you can define logging and recording intervals and customize broadcast strengths. Select a sensor that works well in a range of environments, including cold rooms, greenhouses and cigar cabinets.

The Wi-Fi Water Sensor Provides Alerts of Flooding for Appropriate Action

The Wi-Fi water sensor lets you know in advance about a flooding threat so you can take corrective action to prevent costly home repairs and equipment damage. The unique sensing mechanism notifies the homeowner instantly when the water starts pooling.
