If you are passionate about IT and electronics, like to stay up to date with the latest technology, and don't want to miss even the smallest details, purchase the Tapo T310 Smart Temperature and Humidity Sensor. It automatically turns home electronics on or off when the settings are outside the preset range. Free data storage and visual graphics record temperature and humidity data and create regular data summaries. You will receive instant alerts on your phone when the values are outside the preset ranges. Hang it up with a lanyard, attach it with adhesive or magnets to a surface, or simply place it on a desk. The Tapo Smart Hub (H100) is required.
