Installed weewx 3.8.2 using the script on my raspberry pi
I would like to add a co2 sensor to my weather station.
im using acurite sensors and rtl_433 currently
I have a Cozir gc-0017 co2 sensor 20% range
serial sensor connected to usb to TTL cable
here is how the data comes from the sensor
pi@raspberrypi:~ $ python cozir.py
Python progam to run a Cozir Sensor
CO2 PPM = 40.0
CO2 PPM = 450.0
CO2 PPM = 450.0
CO2 PPM = 450.0
CO2 PPM = 450.0
#Python progam to run a Cozir Sensor
import serial
import time
multiplier = 10 # 20% sensors requires a multiplier
ser = serial.Serial("/dev/ttyUSB0")
print "Python progam to run a Cozir Sensor\n"
ser.write("M 4\r\n") # set display mode to show only CO2
ser.write("K 2\r\n") # set operating mode
# K sets the mode, 2 sets streaming instantaneous CO2 output
# \r\n is CR and LF
ser.flushInput()
time.sleep(1)
while True:
ser.write("Z\r\n")
resp = ser.read(10)
resp = resp[:8]
fltCo2 = float(resp[2:])
print "CO2 PPM = ", fltCo2 * multiplier
time.sleep(1)
i have been reading up on file parse but im in a little over my head.
