With the implemented CO2 sensor we took the performance of those systems to a higher level since they are completely adapted to the received sensor measurements of the CO2. Our CO2 sensor allows you to define a different measuring range with an integrated DIP switch. Indoor CO2 sensor ANDRACO2 and duct CO2 sensor ANDKACO2 allow to set the measuring range from 0 to 2000 ppm (parts per million molecules) or from 0 to 5000 ppm (particles per million molecules). The output signal of both sensors ...

5 HVAC sensors you need to know about Primex HVAC Venting

Ultrasonic waves can pass through solid objects, so they can pick up smaller movements and are more sensitive than PIR sensors. Sensors and indoor air quality. Sensors that measure indoor air quality (IAQ) are becoming increasingly important. The basic IAQ sensor is a carbon sensor, which detects carbon levels in the air. Carbon levels are an indicator of air circulation, and poor air ...

Proximity sensors: Types and applications

Capacitive proximity sensors can be used to metallic nonmetallic objects and substances without any limitation to the state (except for gas). The capacitive sensors can detect the object in any state, powder, granule, liquid, and solid form. As the name suggests, it works on the principle of capacitance, by sensing the variation in capacitance. The amount of capacitance depends on two ...
