RealTime Monitoring The WiFi Temperature & Humidity Sensor provides immediate updates on environmental changes, helping you stay informed about your fish tank conditions. Updates occur at a maximum frequency of every two minutes. Battery Performance Designed for efficiency, the sensor operates on LR03 5V alkaline batteries. Using the correct battery type helps minimize configuration issues and reduces battery drain. Energy Efficiency The sensor conserves battery life by halting network activity when not actively reporting, extending usage between battery replacements. Key benefits Monitors both temperature and humidity to support stable tank conditions Realtime updates keep you informed without constant checks Lowpower operation extends battery life between replacements Simple battery setup with LR03 5V alkaline cells Use scenarios Home tropical fish tank: monitor temperature and room humidity to prevent stress from drafts, heat, or cooler nights, enabling quick adjustments. Small office or apartment aquarium: keep an eye on environmental changes while you're away, ensuring a healthy tank during workdays or travels. Tank maintenance and relocation: track environmental stability during water changes, equipment failures, or moves to minimize stress on fish.
