@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.
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)
