@Yunita-Siagian Hello,
As I mailed to you, It's value is voltage.
To convert to ppm value, You need to calibrate the sensor before use it.
But we don't have knowledge to calibrate it and how to convert it to ppm value. Please refer other articles on the internet.
First, you can check which parts are easy to program with obniz at
https://obniz.io/doc/obnizjs_parts
And each parts page has links to stores.
And There are many famous electrical parts stores like
Adafruit
Sparkfun
Amazon
Hi, @kabongsteve
Ok, obniz will find your iBeacon with this.
var target = {
uuids: ["00004980-968d-11e4-b4a9-0800200c9a66"],
};
var peripheral = await obniz.ble.scan.startOneWait(target);
console.log(peripheral.iBeacon)
