# Seeed-ArduPy-scd30 [](https://travis-ci.com/Seeed-Studio/seeed-ardupy-scd30)
## Introduction
An ArduPy library for Grove - CO2 & Temperature & Humidity Sensor for Arduino (SCD30) - 3-in-1. The Grove - SCD30 is a 3-in-1 Arduino sensor that can measure CO2, temperature, and humidity. Based on Sensirion SCD30, it is a Non-Dispersive Infrared(NDIR) carbon dioxide sensor with high precision and wide measurement accuracy which can reach ±(30 ppm + 3%) between 400ppm to 10000ppm.
## How to binding with ArduPy
- Install [AIP](https://github.com/Seeed-Studio/ardupy-aip)
```shell
pip3 install aip
```
- Build firmware with Seeed ArduPy scd30
```shell
aip install https://github.com/Seeed-Studio/seeed-ardupy-scd30
aip build
```
- Flash new firmware to you ArduPy board
```shell
aip flash [Ardupy Bin PATH]
```
For more examples of using AIP, please refer to [AIP](https://github.com/Seeed-Studio/ardupy-aip).
## Usage
```python
from arduino import grove_scd30
import time
scd30 = grove_scd30()
while True:
if(scd30.isAvailable()):
data = scd30.getCarbonDioxideConcentration()
print("\n-------SCD30 Data Set-------")
print("Carbon Dioxide Concentration:", data[0])
print("Temperature:", data[1])
print("Humidity:", data[2])
time.sleep(1)
```
## API Reference
- **isAvailable(void) : bool** - available
```py
if scd30.isAvailable():
print("SCD30 is connected")
```
- **setAutoSelfCalibration(enable) : void** - Turn ON/OFF self calibration
```py
scd30.setAutoSelfCalibration(True) # Enable auto self calibration
scd30.setAutoSelfCalibration(False) # Disable auto self calibration
```
- **setMeasurementInterval(interval) : void** - Set the measurement interval
```py
scd30.setMeasurementInterval(2) # Sets measurement interval to 2s
```
- **startPeriodicMeasurment(void) : void** - Start periodic measurements
```py
scd30.startPeriodicMeasurment()
```
- **stopMeasurement(void) : void** - Stop measurements
```py
scd30.stopMeasurement()
```
- **setTemperatureOffset(offset) : void** - Sets temperature offset
```py
scd30.setTemperatureOffset(0) # Set temperature offset
```
- **getCarbonDioxideConcentration(void)** : tuple - returns all 3 datas of CO2, temperature and humidity.
```py
data = scd30.getCarbonDioxideConcentration()
print(data[0]) # CO2
print(data[1]) # Temperature
print(data[2]) # Humidity
```
