Quick Verdict
The SwitchBot Motion Sensor scores a solid 7.9/10 in our testing. This compact PIR motion detector covers a 110° detection angle with a 30-foot range, and its CR2 battery lasts an impressive 3+ years. At around $20, it is one of the most affordable motion sensors that can trigger smart home automations — turn on lights when you walk into a room, start a camera recording, or send alerts when motion is detected while you are away. The trade-off is PIR-only detection (no mmWave presence sensing) and a hub requirement for remote notifications.

Detailed Review
Design & Build Quality
The SwitchBot Motion Sensor is a small, round-edged white device that blends into most interiors. It ships with a magnetic base and 3M adhesive pad, giving you flexible mounting options — stick it to a wall, place it on a shelf, or attach it to any metal surface with the magnet. The magnetic mount lets you easily adjust the angle to fine-tune the detection zone. At just a few inches across, it is unobtrusive in any room.
Detection Performance
The PIR sensor reliably detects human movement within its 110-degree field of view and 30-foot range. In our testing, it consistently triggered within 1-2 seconds of someone entering the detection zone. The adjustable sensitivity setting lets you dial it down to reduce false triggers from heat sources or up for maximum coverage. That said, PIR technology only detects movement — if you sit still at a desk, it will register you as absent after the timeout period. For true presence detection, you would need a mmWave sensor.
Automation & Smart Home
Like all SwitchBot sensors, the real value is in automations. Set up the motion sensor to turn on SwitchBot lights when you walk into a room, trigger a SwitchBot Pan/Tilt camera to start recording, or activate a scene when motion is detected during specific hours. With a SwitchBot Hub, you unlock Alexa and Google Home routines, remote alerts via the app, and IFTTT integrations. The sensor also has a built-in light sensor, so you can create rules like “turn on lights only when motion is detected and the room is dark.”
Value for Money
At around $20, the SwitchBot Motion Sensor undercuts most smart motion sensors by a wide margin. The 3+ year battery life means virtually no maintenance cost. You can place multiple sensors throughout your home without breaking the bank, creating a comprehensive motion-triggered automation network for the price of a single premium sensor from competitors.
🎯 Who Is This For?
Smart home users who want affordable motion-triggered automations — automatic lights, security camera triggers, or activity alerts. Great for SwitchBot ecosystem users looking to add room occupancy awareness without spending premium prices. Not ideal if you need pet immunity or true presence detection.

Frequently Asked Questions
Can the SwitchBot Motion Sensor distinguish pets from people?
No, the SwitchBot Motion Sensor does not have a pet immunity setting. It uses PIR detection that triggers on any heat-emitting movement, so pets walking through the detection zone will trigger it. You can try reducing sensitivity or adjusting the mounting angle to minimize false triggers from smaller animals.
How long does the battery last?
SwitchBot rates the CR2 battery at 3+ years under normal usage. This is one of the longest battery lives among smart motion sensors, and most users confirm getting close to the rated lifespan.
Does it work without a SwitchBot Hub?
Yes, but only for local Bluetooth automations with other SwitchBot devices within range. Without a hub, you will not get remote push notifications, cloud automations, or voice assistant integration. The hub is strongly recommended for a complete experience.
Can I use the SwitchBot Motion Sensor outdoors?
No, the SwitchBot Motion Sensor is designed for indoor use only. It is not weather-sealed or rated for outdoor temperatures or moisture exposure. For outdoor motion detection, consider a weatherproof outdoor camera with built-in motion sensing.
