The Tuya Zigbee Smoke Sensor is a wire-free smart home safety device that uses optical technology to detect smoke density, triggering an alarm via indicator lights and an 85dB buzzer, while simultaneously sending real-time push notifications through an app. It is suitable for Hong Kong homes, subdivided units, kitchens, and rental properties. Priced at HK$180 in Hong Kong, it is in stock at LINKO Shop.
Product Introduction
This Tuya Smart Smoke Sensor focuses on "preventing disasters before they happen": it features built-in optical sensing technology to detect smoke concentration, issuing an immediate alarm via indicator lights and a high-decibel buzzer once a threshold is exceeded. It utilizes a next-generation omnidirectional detection design to ensure sufficient sensitivity from every angle. Most importantly, it is completely wire-free, operating on a single CR123A battery (DC3V). An anti-tamper design improves battery longevity by 43%, and installation is simple using the included 3M adhesive or screws—no need to dismantle ceilings or run wires in older or renovated buildings.
Key Features
A core highlight is the smart dual-recognition algorithm: it triggers an alarm when smoke density exceeds a threshold or temperatures rise above 65°C, effectively reducing false alarms. Once connected to a Tuya smart hub (compatible with Momax Smart hosts) via Zigbee, users can manage all smart devices in the home and set up automation scenarios within a single app. If an alarm is triggered, the mobile app receives a push notification, ensuring you are immediately alerted even when away from home. It also supports voice control, is compatible with Google Assistant and Amazon Alexa, and has received CCC fire safety certification.
