Plantower® PTQS1005 5-in-1 Sensor Detector PM2.5 Formaldehyde TVOC Carbon Dioxide Temperature and Humidity

Introduction The PTQS1005 is an all in one gas sensor module that measures multiple gas metrics simultaneously The sensor module incorporates Plantowers laser particle sensor infrared non spectral CO2 sensor and the latest electrochemical and semiconductor principles combined with formaldehyde TVOC sensors for particle concentration carbon dioxide and formaldehyde TVOC concentrations The sensor module also has a built in temperature and humidity sensor chip A variety of parameters will be output in a unified manner in the form of a digital interface By optimizing the internal structure the sensor module better integrates the path of the air inside the module with the sampling interface of each sensor which not only reduces the size of the module but also ensures the sensitivity of each sensor Feature Laser scattering principle to measure particle concentrationElectrochemical and semiconductor principle measurement formaldehyde or VOCInfrared non dispersive principle for measuring carbon dioxideMultiple sensors to unify the air duct optimize space and response speedHighly integrated for user friendly designPrecautions 1 The PTQS1005 requires 5V power supply because the fan requires a 5V drive However other data communication and control pins require 3 3V as the high level Because the motherboard MCU that communicates with it should be powered by 3 3V If the motherboard MCU is powered by 5V a level shifting chip or circuit should be added to the communication
