## si7021.read()
#### Syntax
`si7021.read()`
#### Parameters
none
#### Returns
- `hum` humidity (see note below)
- `temp` temperature (see note below)
- `hum_dec` humidity decimal
- `temp_dec` temperature decimal
!!! note
If using float firmware then `hum` and `temp` are floating point numbers. On an integer firmware, the final values have to be concatenated from `hum` and `hum_dec` / `temp` and `temp_dec`.
#### Example
```lua
local sda, scl = 6, 5
i2c.setup(0, sda, scl, i2c.SLOW) -- call i2c.setup() only once
si7021.setup()
hum, temp, hum_dec, temp_dec = si7021.read()
-- Integer firmware using this example
print(string.format("Humidity:\t\t%d.%03d\nTemperature:\t%d.%03d\n", hum, hum_dec, temp, temp_dec))
-- Float firmware using this example
print("Humidity: "..hum.."\n".."Temperature: "..temp)
```
## si7021.serial()
Read the individualized 64-bit electronic serial number of the Si7021 sensor.
#### Syntax
`si7021.serial()`
#### Parameters
none
#### Returns
- `sna` 32-bit serial number part a
- `snb` 32-bit serial number part b, upper byte contains the device identification
* `0x00` or `0xFF` engineering samples
* `0x0D` `13` Si7013
* `0x14` `20` Si7020
* `0x15` `21` Si7021
#### Example
```lua
local sda, scl = 6, 5
i2c.setup(0, sda, scl, i2c.SLOW) -- call i2c.setup() only once
si7021.setup()
sna, snb = si7021.serial()
print(string.format("SN:\t\t%X%X\nDevice:\tSi70%d", sna, snb, bit.rshift(snb,24)))
```
## si7021.setting()
Settings for the sensors configuration register to adjust measurement resolution, on-chip heater and read the supply voltage status.
