The Grayson TC1 is a combined temperature and CO₂ sensor designed to continuously monitor driver and passenger cabin conditions.
Operating on a 24 V DC supply and communicating via CAN, the TC1 provides real-time environmental data to HVAC systems, enabling automated climate control, optimised fresh air intake and improved cabin comfort across a wide range of vehicle applications.
The TC1 sensor provides continuous measurement of cabin/saloon temperature and carbon dioxide concentration to support intelligent climate control and air quality management.
By transmitting real-time data over CAN, the TC1 enables HVAC systems to automatically regulate temperature, airflow and fresh air intake via dampers, helping maintain passenger comfort while minimising unnecessary energy use.
Designed for integration into vehicle thermal management architectures, the sensor operates on a nominal 24V DC supply and is suitable for both on-highway and off-highway applications.
Its compact form factor supports flexible installation within vehicle cabins, while automated CO₂-based control strategies help optimise ventilation efficiency in varying occupancy and operating conditions.
These technical characteristics help the product operate reliably by maintaining stable and predictable performance.
A combination of design features supports durability, effective thermal control, and straightforward system integration.
Discover why the world’s leading on-highway and off-highway OEMs choose the TC1 to deliver exceptional climate comfort for drivers and passengers.
CO₂ monitoring enables intelligent fresh air management for healthier cabin environments.
