Tapo T100
Best Overall Indoor SensorPros
- Compact and easy to mount
- Reliable PIR detection
- Long battery life (up to 2 years)
Cons
- Requires Tapo H100 hub
- Not weatherproof for outdoor use
The Tapo T100 is the standard indoor motion sensor for the Tapo ecosystem. It uses passive infrared (PIR) technology to detect movement up to 9 meters away with a 120-degree field of view. Owner reviews consistently praise its quick response time and reliable triggering of automations in the Tapo app.
Setup is straightforward through the Tapo app, and the sensor can be placed on a flat surface or mounted to a wall using the included adhesive tape. The CR123A battery is rated for up to two years of typical use. For indoor security and lighting automation, the T100 is the most cost-effective choice.
Tapo T110
Best Outdoor Motion SensorPros
- IP65 weatherproof design
- Adjustable sensitivity
- Works with Tapo outdoor lights
Cons
- Slightly less range than T100
- Requires hub
The Tapo T110 is built for outdoor environments with an IP65 rating that protects against dust and water jets. It detects motion up to 8 meters with a 120-degree angle and includes adjustable sensitivity settings in the Tapo app to reduce false triggers from animals or passing cars.
Owner reviews highlight its sturdy build and reliable performance in rain and snow. The sensor can trigger Tapo outdoor smart plugs or lights, making it a good choice for porch or garden automation. Battery life is similar to the T100 at around two years.
Tapo T200
Best Contact SensorPros
- Detects door/window open/close
- Very small size
- Easy to install
Cons
- No motion detection
- Requires hub
The Tapo T200 is a magnetic contact sensor designed for doors and windows. It detects when a door or window is opened or closed and sends alerts to the Tapo app. Its compact size allows it to fit on most frames without being obtrusive.
Owner reviews note that the magnetic alignment is critical for reliable operation. The CR1632 battery lasts about two years. The T200 is a good addition to a Tapo security system for monitoring entry points.
Tapo T300
Best Temperature/Humidity SensorPros
- Monitors temperature and humidity
- Compact design
- Good for climate control automation
Cons
- No motion detection
- Requires hub
The Tapo T300 measures ambient temperature and humidity levels in a room. It sends data to the Tapo app, where you can set triggers for smart plugs or heaters. It is useful for monitoring conditions in basements, greenhouses, or nurseries.
Owner reviews find the readings accurate within one degree Celsius. The CR2032 battery lasts about one year. The T300 does not detect motion, so it serves a different purpose than the T100 or T110.
Tapo T310
Best Water Leak SensorPros
- Detects water leaks quickly
- Small and discreet
- Alerts via Tapo app
Cons
- No motion detection
- Requires hub
The Tapo T310 is a water leak sensor that detects the presence of water on its probes. It is designed to be placed near water heaters, washing machines, or under sinks. When water is detected, the sensor sends an alert to the Tapo app and can trigger a smart plug to shut off a valve.
Owner reviews note that the sensor is sensitive and responds quickly to small amounts of water. The CR2032 battery lasts about one year. The T310 is a useful addition for preventing water damage in vulnerable areas.
What to check before buying a Tapo motion sensor
Before purchasing a Tapo motion sensor, consider the environment where it will be placed. Indoor sensors like the T100 are not weatherproof, while the T110 is rated for outdoor use. Also check that you have a Tapo H100 hub, as all Tapo sensors require it to connect to Wi-Fi and the Tapo app.
Battery type and life vary between models. The T100 and T110 use CR123A batteries that last up to two years, while the T300 and T310 use smaller CR2032 batteries with about one year of life. Consider the detection range and field of view needed for your space.
Mistakes to avoid
A common mistake is buying a motion sensor without a hub. All Tapo sensors require the H100 hub to function. Another mistake is placing an indoor sensor outdoors, which will lead to failure in wet conditions. Also avoid mounting sensors behind large objects that block the PIR detection field.
Some users overlook the need for the Tapo app for setup and automation. Without the app, the sensors cannot be configured or integrated with other smart home devices. Finally, check that the sensor's battery type is readily available for replacement.
