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();
}
```
