pzem004t

An embedded-hal driver for the PZEM004T energy monitor.

A CLI for the library is available and can be run on all major operating systems (uses serialport crate).

Examples

Examples can be found in the 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();

} ```
