Wireless CO2, Temperature and Humidity Sensor – Pressac

The Pressac Sensing wireless CO2 Sensor is designed to measure and report levels of Carbon Dioxide, ambient temperature and relative humidity in an internal environment. During normal operation, the sensor is powered from ambient room light: in prolonged low light environments the security of battery back-up ensures up to 10* years of continued maintenance free operation. The sensor supports the open EnOcean® standard (ISO/IEC 14543-3-10), facilitating seamless connection with building management systems.

Features and Benefits
