iam-voc-monitor v1.0.0

iam-voc-monitor

This is a node module for the iAM USB indor air quality monitor built by Applied Sensors but distributed under many different brands (e.g. Voltcraft CO-20 Rehau).

Requirements

Needs libusb support (depends on node usb module). Tested on Linux only so far.

Usage

let voc = new iAMVOCMonitor();

voc.on("connected", (device) => {
	console.log("connected");
});

voc.on("error", (error) => {
	console.log(error);
});

voc.on("rawData", (date) => {
	console.log("VOC:", date);
});
voc.connect();
voc.startTransfer();

See demo.js as well.

The iAMVOCMonitor emitts three events:

• error: If a (non-fatal) error occurs during data reads. Passed the error.
• connected: After calling connect() when connected. Passed the libusb device.
• rawData: Emitted when data is read from the sensor. Passed a Number with mesured value. Values range from 450 to 2000 and are measured in ppm (parts per million) equivalent.
