This should be possible. You’ll need to do the following:

  • Install an MQTT broker, Telegraf, InfluxDB, and Chronograf on your AWS EC2 instance, and configure your security groups to allow traffic on all the required ports.

  • Program your NodeMCU to read from the sensor and push data to a the appropriate MQTT topic in one of the Telegraf Input Formats. Looks like there is an MQTT client for this.

  • Configure Telegraf to use the MQTT Consumer input plugin to read data from MQTT and send it to InfluxDB.

  • Create a Chronograf dashboard.
