MEROSS MS120-EU smart humidity and temperature meter

The MEROSS MS120-EU is a smart sensor for monitoring temperature and humidity, with additional readings for absolute humidity, dew point and vapour pressure deficit (VPD). Its 1.9-inch LCD displays measurements, while Bluetooth Low Energy and the Meross app let you check readings and review their history. Set threshold values to receive app notifications or an audible alert of up to 100 dB when conditions move outside your chosen range.

The sensor takes readings every three seconds, with accuracy of ±0.2 °C for temperature and ±2% relative humidity. Its IP65-rated, UV-resistant housing is designed for indoor or outdoor use, with an operating temperature range of -20 °C to 60 °C. It stores data locally for up to 120 days, and readings can be exported. A separately available Meross Bluetooth Hub enables access to up to two years of cloud history. A CR123A battery powers the sensor for up to three years.
