Sensors

Elvaco offers temperature and humidity sensors, both for indoor and outdoor environments. The product line enables simple and cost-effective metering, which enables a more effective use of energy and a better real-estate climate. Sensors are available with M-Bus or Wireless M-Bus communication, as well as with or without display.

CMa11w is a 1-way wireless M-Bus temperature and humidity sensor for indoor use. The sensor offers high accuracy, user-friendliness and a long battery-life (up to 12 years), which makes it the optimal choice for tenant owners. Readouts and configuration are easily performed via wireless M-Bus or by using a mobile phone (via NFC).
