PMS5003 (G5) is a digital versatile particulate matter concentration sensor can be used to get the quality and quantity in the unit volume of suspended particulate matter in the air, and a digital interface in the form of output. The sensor can be embedded in a variety of concentrations of suspended particulate matter in the air or related instrumentation equipment to improve the environment, to provide timely and accurate concentration data.

The sensor uses laser light scattering theory. And even if the scattering of laser irradiation on the suspended particles in the air, while the scattered light is collected at a specific angle, resulting scattered light intensity versus time curve. Furthermore the use of microprocessor-based algorithm theory Michaelis (MIE), obtained an equivalent amount of particulate matter within the size and unit volume of particulate matter of different particle sizes.

 

 

Interface Description

Data interface: two-pin serial data communication interface, the use of a universal asynchronous receiver protocol (UART); 1 pin for the control signal interface, the use of high-low control, all electric 3.3VTTL average level.

 

NOTE: SET = 1 module in continuous sampling mode, the module active uploaded after each sampling end of the sample data, sampling the response time of less than 600 milliseconds, data update time less than 2 seconds.

SET = 0 module enters a low-power standby mode
