PMSA003

Product features
PMSA003 is a kind of digital and universal particle concentration sensor, which can be used to obtain the number of suspended particles in the air, i.e. the concentration of particles, and output them in the form of digital interface.
This sensor can be inserted into variable instruments related to the concentration of suspended particles in the air or other environmental improvement equipments to provide correct concentration data in time.
DC 5V power supply is needed because the FAN should be driven by 5V. But the high level of data pin is 3.3V.

Product description
Main characteristics * Zero false alarm rate. * Real-time response. * Correct data. * Minimum distinguishable particle diameter :0.3 micrometer. * High anti-interference performance because of the patent structure of six sides shielding. * Optional direction of air inlet and outlet in order to adapt the different design. * Smallest. Overview PMSA003 is a kind of digital and universal particle concentration sensor, which can be used to obtain the number of suspended particles in the air, i.e. the concentration of particles, and output them in the form of digital interface. This sensor can be inserted into variable instruments related to the concentration of suspended particles in the air or other environmental improvement equipments to provide correct concentration data in time. Circuit Attentions 1) DC 5V power supply is needed because the FAN should be driven by 5V. But the high level of data pin is 3.3V. Level conversion unit should be used if the power of host MCU is 5V. 2) The SET and RESET pins are pulled up inside so they should not be connected if without usage. 3) PIN7 and PIN8 should not be connected. 4) Stable data should be got at least 30 seconds after the sensor wakeup from the sleep mode because of the fan’s performance.
