SXG Indoor CO2 ppm Gas Sensor
GrowControl™ SXG precision aspirated CO₂ gas sensor for alarm monitoring in indoor growing rooms, with AXG horn-strobes on GCX controllers.
CO₂ Gas Sensor
GrowControl™ SXG is a precision aspirated gas sensor for CO₂ concentration in indoor spaces, designed for alarm monitoring in grow rooms.
Reliable NDIR sensing reads up to 40,000 ppm. The fan aspirates air for continuous accuracy and fast response, and the air filter comes out without tools.

CO₂ Alarm System
The SXG sensor in the grow room reports CO₂ to the GrowControl™ GCX. On an alarm, the AXG horn-strobe at the door warns people outside the room, and the purge button runs the exhaust until CO₂ is back to a safe level.
Installation
Mount the sensor on the grow room wall and connect it to a GrowControl™ GCX as part of a complete facility control system.
- Mount 12 in from the floor, or as local codes require.
- One sensor for every 1,500 sq ft, or as local codes require.
- Service the air filter without tools.
Connect it
Use it with a GrowControl™ GCX, or with PLCs and building automation over MODBUS.
