dht-logger

Read DHT sensor data formatted in JSON over a serial interface and log it.

This crate is still under development and is not stable.

This crate is for logging measurement from a device reading DHT sensors and writing the measurements over a serial connection. The hardware producing the data does not matter, but it must be logging data over serial in JSON with fields for temperature, humidity, and heat index. Here's a pretty version of an example reading:

{
  "sensor_label": {
    "t": 20.0,
    "h": 50.0,
    "hi": 20.0
  },
  "another_sensor": {
    "error": "some error message"
  }
}

This code has been tested using arduino-dht-logger as the hardware source providing data over serial.

Example

The following example creates a DHT logger from a configuration file, then reads data from the serial port and logs it to whatever logging channels are configured.

use std::path::Path;
use dht_logger::DhtLogger;

let config_path = Path::new("example_config.yaml");
let logger = DhtLogger::from_config(config_path);
logger.read_sensor_and_log_data(10);
