The data is decoded from "Manufacturer Specific Data" -field, for more details please check Bluetooth Advertisements section. Manufacturer ID is 0x0499, which gets sent as 0x9904. The actual data payload is:
| Offset | Allowed values | Description |
|---|---|---|
| 0 | 3 | Data format definition (3 = current sensor readings) |
| 1 | 0 ... 200 |
Humidity (one lsb is 0.5%, e.g. 128 is 64%) Values above 100% indicate a fault in sensor. |
| 2 | -127 ... 127, signed |
Temperature (MSB is sign, next 7 bits are decimal value) |
| 3 | 0 ... 99 |
Temperature (fraction, 1/100.) |
| 4 - 5 | 0 ... 65535 |
Pressure (Most Significant Byte first, value - 50kPa) |
| 6-7 | -32767 ... 32767, signed |
Acceleration-X (Most Significant Byte first) |
| 8 - 9 | -32767 ... 32767, signed |
Acceleration-Y (Most Significant Byte first) |
| 10 - 11 | -32767 ... 32767, signed |
Acceleration-Z (Most Significant Byte first) |
| 12 - 13 | 0 ... 65535 |
Battery voltage (millivolts). MSB First |
The first byte tells the receiver (ie. website) what kind of type of data the packet has.
Values supported: -127.99 °C to +127.99 °C in 0.01 °C increments.

| Value | Measurement |
|---|---|
0x0000 |

0x8145 |
-1.69 °C |
0x0145 |
+1.69 °C |
Values supported: 0.0 % to 100 % in 0.5 % increments.
Example

Values supported: 50000 Pa to 115536 Pa in 1 Pa increments.
Example
| Value | Measurement |
|---|---|
00000 |
50000 Pa |
51325 |
101325 Pa (average sea-level pressure) |
65536 |
115536 Pa |
Values supported: -32000 to 32000 (mG), however the sensor on RuuviTag supports only 16 G max (2 G in default configuration). Values are 2-complement int16_t, MSB first. All channels are identical.
Example
| Value | Measurement |
|---|---|
0xFC 0x18 |
-1000 mG |
0x03 0xE8 |
1000 mG |
Values supported: 0 mV to 65536 mV in 1 mV increments, practically 1800 ... 3600 mV.
These test vectors are based on ruuvitag-sensor project. There is no specific value for invalid/not available sensor readings, it is suggested to send 0 if value is not available. The tests are bidirectional, decode-encode results in original raw data. Encode-decode must result in same values with given precision, but floating point rounding differences may occur.
