# Description:

# Read the Analog value and the data of humidity & temperature

# Hardwares:

1. Arduino UNO

2. IO Expansion Shield V5

3. Analogue_Test and SHT1X Module

# Interface: RS485

# Note: Connect the Analogue_Test and SHT1X Module with IO Expansion Shield

V5 through RS485

Set the address of the module in manual,range from 0x02 to 0x7F,take effect

after 30 seconds
