@thehighestbit/node-red-contrib-pmsa003i 1.0.0
Node-RED node for Plantower PMSA003I particle concentration sensor
node-red-contrib-pmsa003i
A Node-RED node for reading particle concentration data from Plantower PMSA003I sensors over I2C.
Installation
cd ~/.node-red
npm install @thehighestbit/node-red-contrib-pmsa003i
Configuration
| Property | Description |
|---|---|
| I2C Address | Sensor address: 0x12 |
| I2C Bus | I2C bus number (default: 1) |
| Read Interval | Polling interval in ms (minimum 1000ms). Leave blank to disable polling. |

Triggering Reads
- Automatic polling: Set a read interval to poll the sensor automatically
- Manual trigger: Send any message to the node input to trigger an immediate read
