RealTime Monitoring This wifi temperature humidity sensor provides immediate alerts and updates readings every two minutes when fluctuations occur. It helps you respond quickly to changes in your refrigerator, fish tank, or other controlled environments. Precise Measurement Accurate sensing with a temperature tolerance of ±12°C and humidity tolerance of ±5% RH. This enables reliable monitoring and accounts for natural delays after temperature changes. EnergyEfficient Design Smart network management reduces nonessential data transmission when idle, conserving LR031.5V alkaline battery power and extending operational life without unnecessary signal tests. Historical Data Storage Stores up to seven days of recorded temperature and humidity history with hourly granularity, enabling analysis and longterm adjustments for improved environmental stability. Use scenarios Monitor a household refrigerator to detect temperature fluctuations that could affect food safety and quality. Manage a fish tank or aquatic habitat to maintain stable environmental conditions and respond to changes quickly. Track climate in other controlled environments such as a greenhouse or storage cabinet to analyze trends and optimize conditions.
