# Pimoroni Enviro+ Drivers
Go library to read data from [Pimoroni's Enviro+](https://learn.pimoroni.com/tutorial/sandyj/getting-started-with-enviro-plus) sensors.
⚠️ Experimental, API subject to change ⚠
## BME250
Package to read pressure, relative humidity and temperature sensors.
```Go
package main
import (
"fmt"
"log"
"periph.io/x/periph/conn/i2c/i2creg"
"periph.io/x/periph/conn/physic"
"periph.io/x/periph/devices/bmxx80"
"periph.io/x/periph/host"
)
func main() {
// Make sure periph is initialized.
if _, err := host.Init(); err != nil {
log.Fatal(err)
}
// Use i2creg I²C bus registry to find the first available I²C bus.
b, err := i2creg.Open("")
if err != nil {
log.Fatalf("failed to open I²C: %v", err)
}
defer b.Close()
d, err := bmxx80.NewI2C(b, 0x76, &bmxx80.DefaultOpts)
if err != nil {
log.Fatalf("failed to initialize bme280: %v", err)
}
e := physic.Env{}
if err := d.Sense(&e); err != nil {
log.Fatal(err)
}
fmt.Printf("%8s %10s %9s\n", e.Temperature, e.Pressure, e.Humidity)
}
```
## LTR559
Light/Proximity Sensor.
The driver is a port of [the Python driver](https://github.com/pimoroni/ltr559-python) from Pimoroni.
### Reading data from the sensor
```Go
// Read proximity and light from the LTR559 sensor
package main
import (
"fmt"
"time"
"github.com/rubiojr/go-enviroplus/ltr559"
)
func main() {
d := ltr559.New()
fmt.Printf("Manufacturer ID: 0x%x\n", d.ManufacturerID())
fmt.Printf("Part ID: 0x%x\n", d.PartID())
for {
fmt.Println("proximity: ", d.Proximity())
fmt.Println(" lux: ", d.Lux())
time.Sleep(1 * time.Second)
}
}
```
### PMS5003
Particle concentration sensor.
```Go
package main
import (
"fmt"
"github.com/rubiojr/go-enviroplus/pms5003"
)
func main() {
dev, err := pms5003.New()
if err != nil {
panic(err)
}
go func() {
dev.StartReading()
}()
for {
r := dev.LastValue()
fmt.Println("-------")
fmt.Println("PM1.0 ug/m3 (ultrafine): ", r.Pm10Std)
fmt.Println("PM2.5 ug/m3 (combustion, organic comp, metals): ", r.Pm25Std)
fmt.Println("PM10 ug/m3 (dust, pollen, mould spores): ", r.Pm100Std)
fmt.Println("PM1.0 ug/m3 (atmos env): ", r.Pm10Env)
fmt.Println("PM2.5 ug/m3 (atmos env): ", r.Pm25Env)
fmt.Println("PM10 ug/m3 (atmos env): ", r.Pm100Env)
fmt.Println("0.3um 1 0.1L air: ", r.Particles3um)
fmt.Println("0.5um 1 0.1L air: ", r.Particles5um)
fmt.Println("1.0um 1 0.1L air: ", r.Particles10um)
fmt.Println("2.5um 1 0.1L air: ", r.Particles25um)
fmt.Println("5um 1 0.1L air: ", r.Particles50um)
fmt.Println("10um 1 0.1L air: ", r.Particles100um)
time.Sleep(1 * time.Second)
}
}
```
