Dust/air quality sensor PM1.0 / PM2.5 / PM10 - PMS5003 - 5V UART

Description

Sensor of dust allows monitoring the air quality, measures the ratio of PM1.0, PM2,5, PM10. Equipped with a sensor that could detect particles with diameter more than 0.3 micrometers, such as cigarette smoke. The system is supplied with the voltage from 4.5 V to 5.5 V, interface UART.

Connection

The sensor has eight outputs, their description is in a table.

 

 

Pin Description Pin 1 VCC - power supply 5 V. Pin 2 The weight of the device. Pin 3 Pin SET Pin 4 RXD / I2C_SCL - receiver, UART / clock line of the I2C bus. Works with a voltage of 3.3 V. Pin 5 TXD / I2C_SDL - transmitter UART / clock line of the I2C bus. Works with a voltage of 3.3 V. Pin 6 Reset. Works with a voltage of 3.3 V. Pin 7

Pin PWM.

8 Pin

Selection between UART and I2C. Low state is the choice of UART, high state - I2C.

By default, in the low state.

This model does not support I2C bus.
