This section is immediately followed by the various CONSTANT declaration.
This section is immediately followed by the various CONSTANT used in the script.

bmp = BME280( i2c=i2c, address=BMP280_I2CADDR )

At the end of initialization section, we do creates the instances for the analog reading (the TMP36, named {{fname|adc}}) and LED controling (named {{fname|led}}).
<syntaxhighlight lang="python">
# TMP36 analog pin
adc = ADC(Pin(26))
# Onboard LED
led = Pin(25, Pin.OUT)

Just before the main loop, the script print the essential data.
<syntaxhighlight lang="python">
# Main Loop
print( 'Frequency :', rfm.frequency_mhz )
print( 'encryption :', rfm.encryption_key )
print( 'NODE_ID :', NODE_ID )
print( 'BASESTATION_ID:', BASESTATION_ID )
print( '***HEADER***' )
print( ":iteration_count,time_sec,pressure_hpa,tmp36_temp,bmp280_temp;" )
print( '***DATA***' )

The main loop is composed of an infinite {{fname|while}} loop.
