node-red-contrib-sds011-dust-sensor 1.0.2

Node-RED node to enable a communication with the SDS011 sensor which is connected via UART/serial connection.

npm install node-red-contrib-sds011-dust-sensor

This is a Node Red node to manage connection to the SDS011 sensor on a Raspberry Pi. It is based on https://github.com/ikhayainkomishi/node-red-contrib-sds011 and documentation resp. Nodes help text was updated to make it easier to use.

All sensors supported modes like constant measurement mode and measuring in certain intervals.

This node works on all devices with a serial port.

Wiring

Make sure you specify correct serial port. The default is /dev/serial0 which is used on Raspberry Pi. Remember to wire Tx <--> Rx correctly.
