Air quality and CO2 sensors - CAREL

General characteristics. CO 2 and VOC (volatile organic compound) air quality sensors are used to measure and monitor the concentration of CO 2 and VOC in air-conditioned commercial and residential environments.. These provide the controller a proportional signal to manage activation of the outside air intake fans when necessary, thus making building climate control more efficient and ensuring ...

Development of an IoT-Based Indoor Air Quality Monitoring ...

· The CO sensor used in the study is also a semiconductor type, which is not the official standard CO sensor for indoor air quality measurements. TES-1372 from TES was used in the experiments for calibration and reliability testing because the Ministry recommended an NDIR-type measurement device. The same calibration method used for the VOC sensor was used for the CO sensor…

Estimating Occupancy from Measurements and Knowledge Using ...

A general approach is proposed to determine occupant behavior (occupancy and activity) in offices and residential buildings in order to use these estimates for improved energy management. Occupant behavior is modelled with a Bayesian network in an unsupervised manner. This algorithm makes use of domain knowledge gathered via questionnaires and recorded sensor data for motion detection, power ...

Construction of Sensitive and Selective Zirconia-Based CO ...

The carbon monoxide (CO) sensitivity of a mixed-potential-type yttria-stabilized zirconia (YSZ)-based tubular-type sensor utilizing a ZnCr2O4 sensing electrode (SE) was tuned by the addition of different precious metal nanoparticles (Ag, Au, Ir, Pd, Pt, Ru and Rh; 1 wt % each) into the sensing layer. After measuring the electromotive force (emf) response of the fabricated SEs to 100 ppm of CO ...

NTC - CAREL

The probes differ for the type of sensor (NTC, PTC Pt1000), type of cap, degree of protection, length of cables, field of work and mechanical dimensions. There are also models of sensors for hydronic use, to be applied directly on the pipeline, which simplify attachment and speed up the reading response, improving the wiring of the HVAC/R unit ...
