Smart Sensors for Home Monitoring

124 products

Smart sensors include Sonoff motion and air quality sensors, Avatto temperature and humidity sensors, Gosund leak and opening sensors, X-Sense carbon monoxide detectors and Shelly energy meters. These devices suit households monitoring room conditions, door activity, water leaks or electricity use. Choose by the measurement or event you need to track, then consider the connection type and your existing smart home setup.



Smart sensors cover indoor conditions, motion, door and window opening, water leaks and electricity consumption. The range includes Sonoff, Avatto and Gosund sensors, X-Sense carbon monoxide detectors, Shelly energy meters and SwitchBot digital thermometers and hygrometers. Sonoff motion sensor mounts are also available. Each device type serves a particular monitoring task, from checking room humidity to detecting an opening or measuring energy use.

How to choose smart sensors for your home

Start with the condition or event you want to monitor and where the device will be installed. Connection options represented include WiFi, Zigbee, Bluetooth and 433 MHz radio. Check the exact model’s compatibility with your setup and any additional equipment requirements. A display is useful when you want to read measurements directly in the room. Consider mounting arrangements alongside connectivity rather than choosing a sensor solely by its appearance.

  • Temperature and humidity: Sonoff and Avatto sensors and SwitchBot thermometers and hygrometers monitor indoor conditions. Compare connectivity and how measurements are displayed.
  • Air quality and carbon monoxide: Sonoff CO2 meters and X-Sense carbon monoxide detectors measure different gases. Select the device for the gas you need to monitor.
  • Motion detection: Sonoff motion sensors detect movement. Choose a location and mounting method appropriate to the room and device instructions.
  • Opening and water leaks: Gosund door and window sensors detect opening, while water leak sensors detect leaks. These are separate device types for different events.
  • Energy monitoring: Shelly smart energy meters measure electricity consumption. Review the installation and connection requirements before fitting an energy meter.
  • Sensor mounts: Sonoff self-adhesive holders provide a mounting option for motion sensors. Match the holder to its intended sensor model.

Temperature, humidity and CO2 measurements support indoor environment monitoring. Opening and leak sensors address specific household events, while energy meters add electricity consumption measurements to home monitoring.

Frequently Asked Questions

Which connection type should I choose for a smart sensor?

A smart sensor’s connection type should match your existing setup. WiFi, Zigbee, Bluetooth and 433 MHz radio are different technologies, so consider any additional equipment requirements as well.

Is a CO2 meter the same as a carbon monoxide detector?

A CO2 meter measures carbon dioxide, while a carbon monoxide detector detects CO. Sonoff CO2 meters and X-Sense carbon monoxide detectors serve different purposes and are not interchangeable.

What is the difference between a motion sensor and an opening sensor?

A motion sensor detects movement, while a door or window opening sensor detects opening. Choose the sensor according to the event you want to monitor.

When is a temperature and humidity sensor with a display useful?

A temperature and humidity sensor with a display is useful for reading measurements directly on the device. Compare which readings each device shows before choosing.
