National Geographic Thermo-hygrometer

The thermo-hygrometer offers the ability to measure temperature and humidity at four different points in and around the house. This allows for easy monitoring at a single location: Is my basement too damp and at risk of mold? Is the baby’s room well-tempered? Is it too hot on the terrace? And many other customizable measurement options. The three remote sensors transmit data to the receiving station via 433 MHz radio frequency, while the receiving station also measures temperature and humidity, providing a total of four measurement results. Features: - Four measurement results for temperature and relative humidity - Early prevention of mold growth - 433 MHz transmission frequency - Remote sensors are splash-proof, making them suitable for outdoor use - Thermo-hygro remote sensors (3 included) - Can be placed or hung - Requires 3x AAA / LR03 batteries (for the main unit) and 6x AAA / LR03 batteries (for the remote sensors).
