A Tasmota node with a SCD41 CO2 sensor with a TM1637 quad 7-segment display

This website contains a new description for a node project which combines:

  • A SuperMini ESP32-c3 development board.
  • A SCD41 CO2 sensor.
  • A TM1637 quad 7-segment display to show the measured value.
  • A RGB LED in a nice chassis holder to show the CO2 levels: green, orange, red.
  • Tasmota software to control everything and publish the sensor values to other IOT devices or domotics systems, e.g. by MQTT.
  • A plastic box that fits all components.

See CO2-Sensor-SCD41-TM1637 for all the details.
