grove-multichannelgassensor-esphome

This are files for the Multi Channel Grove Gas Sensor or mics_6814 sensor

Dependencies:

  • Grove - Multichannel Gas Sensor

Installation

  1. In your ESPHome config folder upload the mics-6814.cpp.h file
  2. In the configuration file for your sensor add the following entry to the esphome block:
  includes:
    - "mics-6814.cpp.h"
  libraries:
    - "Grove - Multichannel Gas Sensor"
  1. To access the sensor values in your ESPHome Config use the following template in your sensor block
- platform: custom
    lambda: |-
      auto my_sensor = new mics_6814();
      App.register_component(my_sensor);
      return {my_sensor->nh3_sensor, my_sensor->co_sensor, my_sensor->no2_sensor, my_sensor->c3h8_sensor, my_sensor->c4h10_sensor, my_sensor->ch4_sensor, my_sensor->h2_sensor, my_sensor->c2h5oh_sensor};
    sensors:
      - name: "NH3 Sensor"
        accuracy_decimals: 2
        unit_of_measurement: 'NH3'
      - name: "CO Sensor"
        accuracy_decimals: 2
        unit_of_measurement: 'ppm'
      - name: "NO2 Sensor"
        accuracy_decimals: 2
        unit_of_measurement: 'µg/m³'
      - name: "C3H8 Sensor"
        accuracy_decimals: 2
        unit_of_measurement: 'ppm'
      - name: "C4H10 Sensor"
        accuracy_decimals: 2
        unit_of_measurement: 'ppm'
      - name: "CH4 Sensor"
        accuracy_decimals: 2
        unit_of_measurement: 'ppm'
      - name: "H2 Sensor"
        accuracy_decimals: 2
        unit_of_measurement: 'ppm'
      - name: "C2H5OH Sensor"
        accuracy_decimals: 2
        unit_of_measurement: 'ppm'

If you get an error saying the Architecture not matched. In the folder where your binaries are for that sensor in the src directory modify MutichannelGasSensor.h by commenting that line along with appending #define _SERIAL Serial
