# -----------------------------------------------------------------------------
# Wemos d1 mini + MH-Z19B + CCS811
#
# DATE: 2021-09-21
#
# MH-Z19B use UART on pins:
#   rx_pin: GPIO3
#   tx_pin: GPIO1
#
# CCS811 use i2c on pins:
#   sda: GPIO4
#   scl: GPIO5
#
# Фильтрация значений - при uptime_sensor < 600s не передавать значения сенсоров
