About This

Built-in and External Sensor: Smart temperature sensor can monitor two ambient temperatures at the same time. The built-in sensor supports monitoring indoor temperature and humidity, and the external probe sensor can detect the external ambient temperature, while all the data is recorded in APP.
Temperature and Humidity Range: Built-in sensor temperature range -9.9°C~60°C (14°F~140°F), humidity 0%~100%RH, external probe temperature range -40°C~120°C (-40°F~240°F). Temperature accuracy ±1℃, humidity accuracy ±5%RH.
Compatible with Smart Life/Tuya Smart APPs: The aquarium thermometer must be connected to Wifi 2.4GHz (5G is not supported), in the APP, you can remotely view the temperature and humidity data of the sensor at any time.The APP supports data export, notification of high and low temperatures, switching of ℉/℃ units, low battery reminder, and more smart operations.
Multiple Occasions: The wifi hygrometer is suitable for rooms, baby rooms, greenhouses, aquariums, kitchens and other occasions. Especially, the external sensor is suitable for monitoring the temperature of the fish tank, and it can also be placed in the refrigerator to monitor the temperature of the freezer. Practical design helps you to achieve multi-occasion temperature monitoring.
What You Will Get: Package includes a 2.9*1.0inch sensor, built-in 2 AAA alkaline batteries, the batteries can last for one year. And a sticker, you can stick it on the fish tank. A magnetic suction, which can be attached to the refrigerator and a suction cup that holds the sensing wire.
