Parts used:<\/strong>
M5 Atom
M5 Env II\/III\/IV unit with SHT30 and xxx
USB Cable
PH2.0-4P interface cable<\/p>\n\n\n\n

    \n
  1. Once you have installed wifi and mqtt you can continue installing an I2C sensor. Of course you can still use the usb to continue.<\/li>\n\n\n\n
  2. Connect the M5 Env III to the M5 Atom via the HY2.0 cable.<\/li>\n\n\n\n
  3. Configure the I2C Port. Goto “Config” pane and enter SDA(26) and SCL(32) pins. “startEnabled” must be checked.<\/li>\n\n\n\n
  4. Click “Save” button.<\/li>\n\n\n\n
  5. Also make sure that the driver is enabled for that session. Click “en” next to the driver in the second column.<\/li>\n\n\n\n
  6. Goto the “Control” pane select the I2C port and click the button scan. You should see some i2C addresses.<\/li>\n<\/ol>\n\n\n\n

    Gratulation your I2C port is set up! Now lets just add a I2C device<\/p>\n\n\n\n

    8. Select the sensor and click the “Control” button. You should get a read out.<\/li>\n\n\n\n
    9. Now create an event so that the sensor is repeatedly reporting the value to the Designer application. To do so follow the next steps<\/li>\n<\/ol>\n\n\n\n

      5. In the code box between the 2 brackets enter a line “me.reportTo(“username”,”username”,”designer”);
        If you want to have the event on startup running then check “onStartEnable”<\/li>\n\n\n\n
      6. Click Save<\/li>\n\n\n\n
      7. This will send every 5 seconds a message to your designer with all the values.<\/li>\n\n\n\n
