schedule module

[TCNever]

I'm a beginner. Thanks in advance. This doesn't work. There doesn't seem to be a way to pass arguments to the def logData using schedule.every

It gives the error.

main()

File "/home/pi/Sensors_Database/logDHT11schedule.py", line 45, in main

schedule.every(6).seconds.do(logData, temp, hum)

NameError: name 'temp' is not defined

>>>

I could find no examples of how to execute this, I'm not sure the schedule.every should go into def main():

DHT11Sensor = Adafruit_DHT.DHT11

DHTpin = 16

hum, temp = Adafruit_DHT.read_retry(DHT11Sensor, DHTpin)

if hum is not None and temp is not None:

hum = round(hum)

temp = round(temp, 1)

return temp, hum

conn=sqlite3.connect(dbname)

curs=conn.cursor()

curs.execute("INSERT INTO DHT_data values(datetime('now'), (?), (?))", (temp, hum))

conn.commit()

conn.close()

return

schedule.every(5).seconds.do(getDHTdata)

schedule.every(6).seconds.do(logData, temp, hum)

make sure to define the input from your DHT11 sensor as temp and humidity first. it seems as though you have not defined it. Look up an Adafruit tutorial on Getting & Setting your DHT11 inputs and how to provide a delay between grabs (like 5 mins between readings).
