An embedded-hal driver for the PZEM004T energy monitor.

A [CLI](https://github.com/iostapyshyn/pzem-cli) for the library is available and can be

run on all major operating systems (uses [serialport](https://crates.io/crates/serialport) crate).

## Examples

Examples can be found in the [`examples/`](https://github.com/iostapyshyn/pzem004t/tree/master/examples) directory.

### Read the measurements off the sensor every second

```rust

let mut pzem = pzem004t::Pzem::new(serial, None).unwrap();

let mut m = pzem004t::Measurement::default();

loop {

    match pzem.read(&mut m, Some((&mut tim, TIMEOUT))) {

        Err(e) => hprintln!("Could not read PZEM004T: {}", e).unwrap(),

        Ok(()) => {

            hprintln!("Voltage: {:.1} V", m.voltage).unwrap();

            hprintln!("Current: {:.3} A", m.current).unwrap();

            hprintln!("Power: {:.1} W", m.power).unwrap();

            hprintln!("Energy: {:.3} kWh", m.energy).unwrap();

            hprintln!("Frequency: {:.1} Hz", m.frequency).unwrap();

            hprintln!("Power factor: {:.2}", m.pf).unwrap();

            hprintln!("Alarm: {}\n", m.alarm).unwrap();

        }

    }

    tim.start(1.hz());

    block!(tim.wait()).unwrap();

}

```
