Tapo Smart Home Sensors – T110 Contact Sensor / T310 Temperature & Humidity Sensor / T315 Temperature & Humidity Monitor with E-Ink Display | Tapo Hub Required
Build a smarter, more responsive home with Tapo Smart Sensors — designed to monitor your environment in real time and automate your daily comfort. Choose the sensor that fits your needs.
Tapo T110 — Smart Contact Sensor
Know the instant a door, window, drawer, or cabinet is opened. The T110 sends real-time push notifications to your phone and can trigger other Tapo devices automatically — lights on when you walk in, alarm when there's unexpected access. Mounts in seconds with 3M adhesive (no tools needed), and runs for over a year on a single CR2032 battery.
Tapo T310 — Smart Temperature & Humidity Sensor
Track room conditions with a Swiss-made sensor accurate to ±0.3°C and ±3% RH, refreshing every 2 seconds. Set comfort thresholds and let the T310 automatically trigger fans, heaters, or humidifiers through Tapo smart plugs. Compact enough to place anywhere — hang it, stick it, or stand it on a desk. Runs up to 2 years on a single CR2450 battery.
Tapo T315 — Smart Temperature & Humidity Monitor with 2.7" E-Ink Display
Everything the T310 does, plus a built-in 2.7" E-Ink screen that shows temperature, humidity, and a comfort-level emoticon at a glance — no phone needed. The glare-free display is readable from metres away in any lighting. Powered by 2 × AAA batteries for up to 2 years.
What All Three Sensors Share
All Tapo sensors work within the Tapo ecosystem and connect through a Tapo Smart Hub (sold separately). Through the Tapo app, you get instant alerts when conditions change, smart automation with other Tapo devices, voice control via Alexa and Google Assistant, and up to 2 years of free cloud data storage with CSV export (T310 & T315).
Important: A Tapo Smart Hub (e.g. H100) is required for all three sensors and is sold separately.
