Temperature
| 2-byte signed integer with negative value below zero
The default unit is 0.1 degrees, that is 201 means 20.1 degrees
e.g. 0xFF88 is -120 (-12℃), Network byte order mode is {04 FF 88}
Humidity(0x05)
| Type 1 Byte | Value 1 Byte | Comments |

Humidity
| Unsigned integer of 1 byte.
The default unit is 1%RH, that is 10 means 10%RH
FRMPayload Example: 00 3F 24 04 01 1C 05 3E 00 3F24 Device Information, Version is 0x01, level is 0x1F = 31 04 011C Temperature is 0x011C = 284 = 28.4 ℃ 05 3E Humidity is 0x3E = 62 = 62 %RH
Local Configuration
Note: Factory reset data uploading is every 10 mins, customers can change data uploading frequency as below: Connect sensor with a USB-C cable to computer for local configuration, through local configuration, you can change the packet frequency. Refer SensorTool Manual.
