Portable CO2 Temperature Humidity Monitor Air Quality Monitor Infrared NDIR Detector Indoor Outdoor Detection ToolsDescription:This product is an air quality monitor that detects Carbon dioxide (CO2),Temperature, and Humidity. it combines sensors real-time monitoring of Carbon dioxide (CO2), temperature, and humidity on its display.
MP-5 gas sensor is for flammable gases.As LPG gas sensor,It adopts multilayer thick film manufacturing technology.The heater and metal oxide semiconductor material on the ceramic substrate of subminiature Al2O3 are fetched out by electrode down-lead,encapsulated in metal socket and cap. Conductivity of the sensor is affected by the concentration of target gas. The higher the concentration is,the higher conductivity of sensor gets. Users can adopt simple circuit to convert variation of conductivity into output signal corresponding to gas concentration.
Digital PIR sensor RDA226, is an integrated design of sensitive element and signal processing chip, packaged sensitive element and IC chip into sensor shield. Sensitive element transfer the human movement signal to high-precision digital chip for data processing. Then the sensor gives digital signal for easy using.
