| Tuya WiFi Smart Temperature & Humidity Sensor: WiFi/ZigBee dual-connect, tamper-proof, 30-day data. Low-battery alert, Alexa/Google Home compatible, fits baby room/warehouse for remote monitoring. | |||||||||




















Detection Range & Accuracy:
Temperature Detection: Range from -10℃ to 60℃, covering scenarios from low winter temperatures (e.g., unheated rooms in northern China) to high summer temperatures (e.g., unairconditioned balconies), meeting full-season monitoring needs.
Humidity Detection: Range from 0 to 100%RH, capturing full humidity changes from dry environments (heated rooms in northern China) to high-humidity spaces (plum rain seasons in southern China, bathrooms), with an accuracy of 3%RH for minimal data error.
Working Environment: Adaptable to a temperature range of -10℃ to 50℃ and humidity up to 95%RH, enabling stable operation in most indoor and semi-open scenarios (e.g., garages, storage rooms) without being affected by short-term extreme conditions.
Power Supply & Energy Management:
Powered by 2 x 1.5V AAA batteries (batteries not included in the package), supporting "percentage display" of remaining battery power. Users can check power consumption in real time via the APP.
Equipped with a low-battery reminder function: When power is low, the APP sends an instant notification to prevent monitoring interruptions due to battery exhaustion. It also supports customizing data collection and reporting frequencies based on battery status to balance battery life and monitoring frequency.
Data Storage & Display:
Supports 30 days of historical data storage. The APP can generate temperature and humidity change curves, and calculate daily/time-period average, maximum, and minimum values, facilitating traceability of environmental fluctuation patterns.
Temperature units can be freely switched between ℃ and ℉, adapting to different users’ habits (e.g., ℃ in China, ℉ overseas).
Material & Dimensions:
The shell is made of ABS material, combining durability and light weight, and is not easily damaged by collisions. The product dimensions are approximately 70×25×20mm (2.75×0.98×0.78inch), with a packaging size of 7.5×4.6×2.5cm and a single gross weight of 0.21kg. Its compact size saves space.
Featuring a minimalist design, it easily integrates with various scene decors, with no complicated decorations, making it suitable for homes, hotels, and other environments that value aesthetics.
Installation Method:
No wiring is required; it can be installed with the included sticker ("easilystick it to the wall with the sticker"). No drilling or professional tools are needed, and ordinary users can complete the installation independently.
Lightweight and firmly adhesive, it can be installed on walls, inside wardrobes, next to refrigerators, or on warehouse shelves, without being limited by power outlets.
Wireless Connection:
Supports dual WiFi & ZigBee connections (wireless technology: WiFi/ZigBee). WiFi is compatible with the 2.4GHz band and can connect directly to home/commercial WiFi routers (no additional hub required); ZigBee mode needs to be paired with a Tuya ZigBee gateway, suitable for whole-house smart linkage scenarios with more stable signals and lower energy consumption.
Compatible with two mainstream APPs: "Tuya Smart" and "Smart Life". The network configuration process is simple, allowing beginners to quickly add devices and set parameters.
Voice & APP Control:
Voice control supports Amazon Alexa, Google Home, and Tmall Genie. Real-time temperature and humidity data can be obtained via voice commands (e.g., "Alexa, check the baby room temperature"), freeing hands.
Comprehensive APP functions: Set upper and lower temperature/humidity thresholds, view 30-day historical curves, customize linkage scenarios, share devices with family members (for joint management), and add devices to the mobile phone home screen for quick access.
Multi-Dimensional Alerts: In addition to alerts for temperature/humidity exceeding thresholds, it supports device offline notifications (the APP sends an instant alert when the device is powered off or disconnected from the network), avoiding monitoring blind spots caused by device failures.
Tamper-Proof Function: The tamper-proof mode can be manually enabled. When the sensor is moved, disassembled, or damaged, the user will immediately receive an APP alert, enhancing security in commercial scenarios (e.g., warehouses, hotels).
Compliance Certifications: Certified by CE and RoHS, meeting environmental protection and safety standards, and can be safely used in homes (especially baby rooms) and commercial scenarios.
Full-Scenario Real-Time Data Collection: Collects temperature and humidity data every second (customizable frequency) with low APP synchronization delay, enabling timely capture of environmental mutations (e.g., sudden temperature rise due to air conditioner shutdown, sudden humidity drop due to humidifier failure).
Multi-Scenario Alert Mechanism: The APP sends alerts when temperature/humidity exceeds preset thresholds; instant notifications are sent when the device is offline (power failure/disconnection); quick alerts are triggered when the sensor is tampered with. It covers three types of risks: "environmental anomalies + device anomalies + safety anomalies" with no monitoring gaps.
Intuitive Data Presentation: 30-day historical data is displayed in curves and numerical values, with clear average, maximum, and minimum values. Users can analyze environmental changes without manual recording (e.g., "The humidity in the baby room has been below 40% at night for the past 7 days; the humidifier runtime needs to be increased").
DIY Automated Scenarios: Supports "Tap-to-Run" and "Automation" modes, allowing users to customize linkage rules, such as:
Automatically triggering smart air conditioner cooling when temperature > 32.6℃;
Linking with a WiFi humidifier to turn on when humidity < 68%;
Synchronously sending APP alerts, phone calls, or SMS notifications when warehouse temperature > 40℃ (safety limit for tobacco storage) to prevent valuable items from deteriorating.
Cross-Ecosystem Device Compatibility: As a Tuya ecosystem device, it can link with smart air conditioners, humidifiers, dehumidifiers, infrared remote controls, etc., without additional adaptation, directly realizing "environment-device" adaptive adjustment and creating a whole-house smart closed loop.
Low Energy Consumption & Long Battery Life: Powered by AAA batteries, combined with customizable collection frequencies (e.g., reducing reporting frequency when battery is low), it has strong battery life, reducing the hassle of frequent battery replacement. The percentage display of battery power allows users to plan spare batteries in advance to avoid sudden power failure.
Minimalist Installation & Configuration: No professional electrician or tools are needed; it can be fixed with a sticker. The APP provides guided network configuration with simple steps (select device - connect to WiFi - complete addition), allowing the elderly and beginners to get started quickly.
Multi-Person Shared Management: Supports sharing devices with family members via the APP (e.g., parents jointly managing the baby room’s temperature and humidity, warehouse managers jointly monitoring the storage environment) without repeated addition, with flexible permission management.
Baby Room (Core Scenario):
Infants have immature temperature regulation systems and require a constant temperature of around 22℃ (not lower than 18℃ or higher than 28℃) and a suitable humidity of around 50% (to prevent dry air from damaging the respiratory system and high humidity from breeding bacteria). The sensor can link with air conditioners and humidifiers to automatically maintain a stable environment. Parents can check data remotely via the APP without frequently entering the room to disturb the baby’s sleep.
Regular Bedrooms/Living Rooms:
Automatically turns on the air conditioner when the temperature exceeds 30℃ in summer, and turns on the humidifier when the humidity is below 35% in winter, creating a comfortable living environment. Temperature and humidity can be checked via voice at night without turning on lights, avoiding disrupting sleep.
Home Storage Areas (Refrigerators/Wardrobes/Musical Instrument Storage Areas):
Monitors the temperature inside refrigerators (to prevent food spoilage due to refrigeration failure), wardrobe humidity (to prevent clothes from mildewing), and the storage environment of musical instruments (e.g., pianos require 40%-60%RH to avoid wood cracking), with instant alerts for anomalies.
Warehouses (Sensitive Item Storage):
Used to monitor temperature and humidity for items sensitive to environmental conditions, such as tobacco, alcohol, food raw materials, and precision musical instruments. For example, alcohol storage requires a temperature ≤ 30℃; the sensor sends APP + phone alerts when the threshold is exceeded to prevent volatilization or deterioration. Electronic component warehouses require humidity ≤ 60%RH to avoid short circuits caused by moisture.
Hotel Guest Rooms:
Installed in guest rooms, hotel management can remotely monitor the temperature and humidity of each room via the APP. If the environment is abnormal (e.g., excessively high temperature due to air conditioner failure), staff can be dispatched to adjust in time, improving guests’ living experience and avoiding complaints.
Small Stores (e.g., Convenience Stores, Music Stores):
Convenience stores monitor the temperature of refrigerated cabinets to prevent drinks and food from spoiling; music stores monitor the humidity of musical instrument storage areas to protect wooden instruments such as guitars and violins, reducing maintenance costs.
