The mod.RFM-AMB is a temperature and humidity sensor that gathers and transmits data over Wireless M-BUS from rooms where it is mounted.
The module stores the month average data up to the 12 months prior and saves the current minimum, maximum, and average data discovered in the most recent hour and day.
Equipped with an anti-removal alarm for a system that is both safer and more effective.
