TR9277-EO is a zero energy carbon dioxide, temperature, and humidity transmitter that harvests power from indoor ambient light. The sensor is wireless, requires no maintenance, and can be installed and integrated into an EnOcean network quickly. An optional battery that operates for 5 years on its own provides extended backup in low light conditions. Installation cost can be reduced by $1,000-3,000 per sensor, making it ideal for retrofit or zero energy buildings.
