Realtime monitoring you can rely on This WiFi Temperature & Humidity Sensor provides immediate updates on environmental changes, helping you stay informed about your fish tank conditions with updates every two minutes at most. Battery performance you can trust Designed for efficiency, the sensor operates with LR03 5V alkaline batteries. Using the correct battery type helps prevent configuration failures and reduces unnecessary battery drain. Energy efficiency that extends usage The sensor conserves battery life by halting network activity when not actively reporting, improving overall efficiency and prolonging time between battery replacements. Why this stands out Combines realtime environmental data with energyconscious operation to deliver reliable monitoring with minimal maintenance. Key attributes Function: monitors temperature and humidity via WiFi with frequent updates. Compatibility: designed to use LR03 5V alkaline batteries for reliable operation. Performance: updates are provided at a maximum frequency of every two minutes; powersaving behavior enhances battery life. Practical use scenarios Home aquarium care: Monitor temperature and humidity around the fish tank to detect fluctuations that could affect fish and plants, enabling timely adjustments. Vacation or remote monitoring: Keep tabs on tank conditions while away from home, with batteryefficient operation reducing the need for frequent changes. Small offices or classrooms: Maintain stable environmental conditions for compact aquariums or terrariums in spaces with variable HVAC activity.
