K-30 10,000ppm CO2 Sensor

SE-0018  K30 STA
SE-0127  K30 ASCII

The K-30 Sensor Module is a maintenance-free transmitter module intended to be built into different host devices that require CO2 monitoring data. It is an accurate, yet low-cost solution for OEMs who want to integrate CO2 sensing into their products. The compact size, low-power requirements and multiple output options are intended to be easily implement into analog or microprocessor-based controls and equipment.

The sensor may be customized in order to optimize the total system with respect to the OEM application. For example, the K-30 can be used in

• IAQ sensor housings
• Air handling units
• Alarm sensor housings
• Fresh air ventilators
• Air conditioning in cars
• Kitchen appliances, fans
• Automatic window openers
• Combustion controls

The only restriction for this product is your creativity and inventiveness.

The K-30 is aimed at high volume production. For a moderate start-up cost this product can be tailored to meet the your unique requests. Contact us directly for wholesale pricing on large quantities of this sensor.

• Operating Environment: Residential, commercial, industrial spaces and potentially dusty air ducts used in HVAC (Heating Ventilation and Air-Conditioning) systems
• Simple to install, pre-calibrated and ready-to-use
• compact, low cost
• maintenance free in normal IAQ applications
• flexible through advanced digital technology 
• Development kit for fast prototypes
