4.2 Data frame format definition

Adopt Modbus-RTU communication protocol, the format is as follows:
Initial structure ≥ 4 bytes of time
Address code = 1 byte
Noise Transmitter Instruction Manual (Type 485) V2.0
Function code = 1 byte
Data area = N bytes
Error check = 16-bit CRC code
End structure ≥ 4 bytes of time
Address code: is the address of the transmitter, which is unique in the communication network (factory default 0x01).
Function code: The instruction function of the command sent by the host. This transmitter only uses function code 0x03 (read register data).
Data area: The data area is the specific communication data. Note that the 16bits data high byte is in front!
CRC code: Two-byte check code.

PM2.5 calculation:

Air quality (PM2.5/P10) transmitter instruction manual (type 485) V2.0
PM2.5:0055 H (hexadecimal) = 85=> PM2.5 = 85ug/m3
PM10 calculation:

PM10:009CH (hexadecimal) = 156 => PM10 = 156ug/m3
Package includes:

1x PM2.5/PM10 Sensor

Sizing & Fit Guide

Please be aware that most of our clothing is Juniors' sizing, which runs smaller than regular US / European Women sizing. Refer to the measurements chart for each individual product to determine the best size for you. Product specific size chart and information can be found in product description or in product picture gallery.

Our team does it's best to include accurate size details and measurement of each item in the product descriptions. If you have questions regarding sizing or any other information on a specific item, please email us at support@mrslm.com for specific details.

Find the best size

When comparing your measurements to those listed on the site, make sure to check if the fabric is stretchy or not. If it is, it can stretch an inch or more.

  • Bust: Wrap the measuring tape loosely around the fullest part of your bust to ensure a comfortable fit.
  • Waist: Measure the narrowest part of your natural waist, holding the measuring tape loose enough to fit comfortably.
  • Hips: Drape the measuring tape around the widest part of your hips, resting the tape comfortably against your body.
  • Length: For tops and dresses, measure from the top of your shoulder to the hem. For strapless dresses, measure from the highest part of the neckline to the hem. For pants and skirts, measure from the top of the waist to the hem.
  • Sleeve: With your arm outstretched, measure from the base of your neck to the end of the sleeve hem to determine where the sleeve length will fall on you.
