GPIO_PIN = 17 # Which GPIO pin you're using to control the fan. def get_temp (): """Get the core temperature. Run a shell script to get the core temp and parse the output. Its pin configuration is shown below. It is a 16 pin. I made a computer fan controller because the stock fan came on too loud. The stock 2 wire fan had only off and fully on, sounded like a jet engine when it came on- very startling. The idea was to measure the fan speed, measure the exhaust air temperature, and use pwm to control the fan speed. The easy way to do this is to use a quiet 4 wire fan. . So I got a Noctua PPC 3000 PWM and needed a way for it to reduce it's speed when needed as it's quite loud and it does not always have to run at max speed. Looked for a PWM controller with temperature based control but could not. @tom_l I have recently got an ESP8266 with integrated fets (Sinilink XY-WFMS), and have been trying to control a 5V fan in the same way @corvy is. I've used this thread as a rough guide and have noticed that I get coil whine at low freqs as you mentioned above. I set the frequency to 20KHz as you suggested, but I lose speed control all together. I have this temperature controller in my basement that I designed, its an NodeMCU board ( ESP8266 Wifi module ) that I program with the Arduino software.

By riq - Tue Apr 19, 2016 1:46 am. I've been using NodeMCU (Lua) with PWM and I couldn't get PWM frequencies higher than 100hz. I don't know if this is a hardware limitation (esp8266) or a framework limitation (nodeMCU). so, my question is: is possible to get higher PWM frequencies using Sming?. Some important points to remember while configuring PWM Channel in ESP32: As there are 16 PWM channels, the ‘channel’ argument takes any value between 0 and 15. Next is the frequency of the PWM signal. You can set the frequency as per your requirements like 1 KHz, 5 KHz, 8 KHz, and 10 KHz. The resolution of the PWM is also configurable and. The fan with the new fan control runs at maximum 10VDC which seems adequate for the psu ventilation. It might be worth changing the fan for a 12V model if you intend to use much power from the PSU. Variable speed fan. The fan from the control board is run using the PWM output from the ESP8266. This allows thresholds to be set for the fan speed.

In our case fanSpeed will have a value of 32 at tempMin and 255 at tempMax. These values are used to control the speed of the fan using PWM and the analogWrite (). The fanLCD re-maps the temp to allow the display of fanSpeed in a 0 to 100% range so you can say that the speed of the fan is directly dependent of the LM35’s temperature. I controlled 220Vac light bulbs and a Fan using my cell phone and computer. So, if you guys want to control AC or DC loads using relays then you should definitely read this article.

These are the contact points where the 4 terminals of speed are connected. on the ESP8266, i would recommend making the PWM ultrasonic to avoid "kick noise": Fan working speed is calculated in a 0 – 100% scale as a ratio between current temperature and the maximum allowed deviation (5º C). I set the frequency to 20KHz as you suggested. The ESP32/ESP8266 hosts a web server that shows the latest temperature readings from a DS18B20 temperature sensor. There's an input field to set up a temperature threshold value. When the temperature goes above the threshold, an output will be automatically turned on. You can invert this logic depending on your project application. To generate a PWM signal on the ESP8266 pins with Arduino IDE, use analogWrite (pin, value). The value is an integer between 0 and 255. For ESP8266 releases before 3.0, the default range is between 0 and 1023. The PWM range may be changed by calling analogWriteRange (new_range).
