CO2 Controllers | CO2 Controllers For Grow Rooms

The best CO2 controllers will have photocell, which allows for easy synchronization of grow light schedules and devices that operate on the same schedule as grow lights (fans, CO2 devices). Some controllers have an integrated CO2 sensor, and others have a remote CO2 sensor. The CO2 sensor is what measures CO2 levels in the air.

Wireless Sensors for Lighting Energy Savings

the sensor. When a warm object like a person passes by, the sensor detects the heat, which causes a positive diferential change between the two halves of the sensor. When the warm body leaves the sensing area, the sensor generates a negative diferential change. These change pulses are what is detected. The assembly is contained in a housing with
