Smart WiFi Temperature and Humidity Sensor Why you need it Continuous monitoring of indoor temperature and humidity helps maintain comfort and protect sensitive items. This sensor links to other smart devices to trigger heating, cooling, humidifiers, or dehumidifiers automatically when preset thresholds are reached. Designed for long battery life with a low power hardware design and very low standby current, so it can operate reliably for extended periods without frequent battery changes. Easy to share data with family members and control via voice assistants for hands operation. Key features Accurate environment monitoring: reports temperature and relative humidity in real time for reliable automation and monitoring. Low power design: runs on two LR03 (AAA) batteries providing DC 3 V and a quiescent current of less than or equal to 30 microamps. Lowpower undervoltage protection activates at less than or equal to 2.7 V. Wireless connectivity: supports WiFi 802.11b/g/n at 2.4 GHz for cloud access and remote control. Wide operating range: works from 10 to 55 degrees C and 10 percent to 90 percent RH. Intelligent linkage: set triggers so other devices act automatically, for example turn on air conditioning when temperature exceeds 35 degrees C or activate a humidifier when humidity falls below 20 percent RH. App control and configuration: configure alarm thresholds, choose Celsius or Fahrenheit, and view realtime readings from the app. Shareable device access: allow family members to monitor and control the sensor from their own app accounts. Voice control compatibility: works with Alexa and Google Assistant for voice queries and simple commands. Audible alert: builtin buzzer provides local alarm notifications. Setup overview Scan the QR code on the device or download the compatible smart home app from your device app store. Register an account using an email address, open the app, tap Home then Add Device, select Sensors, and choose the Temperature and Humidity Sensor WiFi option. Connect the sensor to your network using the available connection modes such as Bluetooth mode or EZ mode. After WiFi connection is complete, tap the sensor icon in the app to set alarm thresholds, units, and automation rules.
