Wireless Convenience: Seamlessly connect to your WiFi network for real-time temperature and humidity updates directly to your smartphone via the dedicated app. Monitor conditions from anywhere without the need for complex installations. Energy Efficient: Operating on a low wattage of 3V, this sensor is designed to conserve energy while providing continuous and reliable readings, making it both eco-friendly and cost-effective. Its compliance with strict standards ensures top-notch performance and peace of mind. Versatile Application: Not just for cold storage, this sensor is also perfect for other sensitive environments requiring careful monitoring, such as wine cellars and greenhouses, offering versatility and precision. Description/Features: It is designed to provide accurate temperature readings but does not support real-time data reporting or humidity measurement with external sensors. External sensors are not suitable for use in consumables such as food or water. A stable WiFi 2.4GHz connection is required for operation. The device updates temperature and humidity data based on a trigger mechanism, with updates typically occurring once per hour, and can be as frequent as every two minutes under certain conditions. Specifications: Network Requirements: WiFi 2.4GHz Battery Requirements: Only LR03-1.5V alkaline batteries are compatible. Do not mix different brands or and old batteries to avoid configuration issues and excessive battery drain. Temperature and Humidity Accuracy: ±1~5°C for temperature and ±5% RH for humidity. Allow 30 minutes for the sensor to adjust
