Multi-Parameter, High-Precision Environmental Monitoring: Measure temperature, relative humidity, absolute humidity, dew point and VPD on the clear 1.9-inch display. With ±0.2°C temperature and ±2% RH humidity accuracy, this digital room thermometer and digital hygrometer works as a room temperature monitor and temperature and humidity monitor for bedrooms, baby rooms, greenhouses, basements, and laundry rooms. It is suitable for everyday environmental monitoring in a range of indoor settings.
Includes Matter Hub MSH450P for Remote Monitoring: Includes 1 MS120 sensor and 1 MSH450P Matter Hub for remote monitoring, app alerts and smart-home automations. With up to 150m signal coverage under suitable conditions, it connects your sensor to compatible smart-home systems, including Home Assistant, Apple Home, Alexa and Google Home. Used with compatible smart-home devices, it can be used for routines to switch on a humidifier when humidity is low, close an outdoor shade when temperatures rise, or start a laundry room fan when humidity is high. Range varies with walls and interference; supported functions depend on the platform and configuration.
IP66 All-Weather Protection for Indoor and Outdoor Monitoring: Designed for varied environments, Meross IP66 outdoor temperature sensor features a UV-resistant housing and operates from -20°C to 60°C. Use it as a greenhouse thermometer to track changing conditions in greenhouses, balconies, garages, basements and storage areas. It is suitable for monitoring in appropriate indoor and outdoor locations. IP66 protection helps resist water and dust but does not mean the sensor is suitable for immersion.
Local Buzzer and Custom Hub Voice Alerts: The sensor's built-in buzzer sounds a local alarm when readings cross your set thresholds, while the compatible Hub can trigger additional alerts and custom voice announcements, such as “The bedroom sensor is sounding an alarm.” Clear location-based announcements help even family members unfamiliar with the device identify the source of an alert and respond promptly. App notifications and Hub alerts require the compatible Hub and supported settings. The system is capable of providing both local and Hub-based alerts when correctly configured.
Up to 3 Years of Battery Life: Powered by a CR123A battery, this wireless thermometer offers up to 3 years of battery life under stated conditions, helping reduce battery replacement frequency and maintenance costs. Its compact, lightweight design, easy-to-read display and wireless setup allow flexible placement without complex wiring. Connect your phone directly to the Bluetooth thermometer over Bluetooth for nearby readings without a Hub or internet connection, making it practical for fixed monitoring in bedrooms and wine cellars, as well as mobile use during camping trips, caravan travel and temporary storage inspections. It is suitable for flexible monitoring at home and on the move.
Historical Data for Better Environmental Management: This smart thermometer and humidity monitor stores up to 120 days of readings locally, even when the internet is unavailable, and retains cloud history for up to 2 years with the Hub. Review trend charts and export data to assess greenhouse growing conditions, investigate humidity patterns associated with mould risk in storage areas, or track damp cycles in basements. These historical insights help UK growers and storage businesses review environmental conditions and optimise their monitoring and control strategies. The stored data can be used for ongoing environmental reviews and planning.
