Temperature regulated fan on RPI
-
I need some help (again).
I made a temperature regulated fan following these instructions:
https://www.npmjs.com/package/rpi-fan-controller
It works fine, but the fan starts at the default 45 degrees celsius.
I would like to change that to 55 or 60 degrees celcius.
I tried several things, but no succes.
Thanks foor any help.

I think more information is needed. Did you run the script with
sudo rpifan -t 55
orsudo rpifan --maxtemp 55
? -
why not just using a python script?
found this one here:
#!/usr/bin/env python3 # coding: utf-8 import os import time import signal import sys import RPi.GPIO as GPIO pin = 36 # The pin ID, edit here to change it maxTMP = 50 # The maximum temperature in Celsius after which we trigger the fan GPIO.setmode (GPIO.BOARD) def setup(): GPIO.setmode(GPIO.BOARD) GPIO.setup(pin,GPIO.OUT) GPIO.setwarnings(False) return() def getCPUtemperature(): res = os.popen('vcgencmd measure_temp').readline() temp =(res.replace("temp=","").replace("'C\n","")) print("temp is {0}".format(temp)) #Uncomment here for testing return temp def fanON(): setPin(True) return() def fanOFF(): setPin(False) return() def getTEMP(): CPU_temp = float(getCPUtemperature()) if CPU_temp>maxTMP: fanON() else: fanOFF() return() def setPin(mode): # A little redundant function but useful if you want to add logging GPIO.output(pin, mode) return() try: setup() while True: getTEMP() time. sleep(8) # Read the temperature every 5 sec, increase or decrease this limit if you want except KeyboardInterrupt: # trap a CTRL+C keyboard interrupt GPIO.cleanup()
