I found a Robotdyn AC dimmer module, but I am not sure if this would work with a fan. How to program for ESP32 to turn fan on/off. I’m thinking adding an exhaust fan to my workshop. The system ensures continuous operation even when Wi-Fi or MQTT Commander Pro 1: RGB Hub 1 has 6 QL fans plugged into it. Or possibly use the one in the ESP32 if it is precise enough. Basically NPN transistors act like a diode between the base and emitter legs, and diodes have a forwards voltage drop across them. 3v and the fan needs 5v for the PWM and 12v for the motor. Reused an old fan remote (RF 403Mhz) and piggy backed the temporary action switches to the esp32. Once reached turn off fan til temp drops and needs to go up to preset temp. Nicely written response. Might be adding more features before ordering like a header and more fan outputs. The ESP32 series employs either a Tensilica Xtensa LX6, Xtensa LX7 or a RiscV processor, and both dual-core and single-core variations are available. : 24V 4wire(+ - FG PWM) FG is sensor that generate pulse. I intend this to be used to control the fans in my enclosed rack. RGB Hub 2 has 6 QL fans plugged into it. Main features are: mode 2 (climate mode or temperature controller mode): fan speed automatically increases if temperature is getting close to or higher than target temperature. The board has ESP32-WROOM-32UE which has an IPEX connector for an external antenna. I’ve got a spare 10A 12V DC fan that I can use. 3v, GND and a GPIO pin to the MOSFET. I couldn't get it to show up as game controller but it did connect to my iOS device. Thank you for your mosfet module suggestion. First you have to, obviously, get yourself an ESP board with WLED installed, ideally it should be ESP32, cuz it can handle 10 channels for various devices, but ESP8266 will also work. So here's how to make your own DIY controller for ARGB PC components with WLED and SignalRGB control. com/datasheets/2634799. S. You only need a single thermometer.

Creating an ESP32 Fan controller. The devices in question are: olimex esp32-poe-iso, and a SANYODENKI San Ace 80 PWM fan The esp32 works at 3. For the 4pin you also provide a pwm signal but the chip inside the fan controls the speed. When you turn on the ESP32 GPIO pin, the logic level converter will convert the 3. This 5V signal will then be sent to the PWM input of the fan, which will control the speed of the fan. This is a basic project to control a PWM based 4-pin fan using an encoder knob and a TTGO Display T1. A reset button could be useful. ) I replaced it with a WiFi-capable fan with a Bluetooth remote. I built a ESPHome Fan Controller. Or check it out in the app stores AC Infinity Fan Controller for ESP32's and DIY AC Infinity Dongle TTGO fan controller. Below is the ESPHome code running my fans (I have two sets of fans run from one ESP) You will need a level shifter for the PWM control pin because the ESP32 is 3. May 9, 2024 · I have a question about controlling a 3-wired PWM fan. One will drive a blower to operate the fan that feeds air to the charcoal depending on the temperature needs. Specifically wanted it to be able to shut off via software and the fan had to be replaceable - hence header pins. Plenty of people have slipped with a probe while the esp was controlling the higher powered device, blowing the fet up and the esp and often the uart driver in the connected laptop. 3V logic level, but PWM is 5V only, i tried some solutions with a mosfet, but it just seems to pass the same 3. I'm working with the same fan as in this thread. It uses an ESP32 microcontroller and supports MQTT over Wi-Fi to report sensor data and fan speeds. Works beautifully. I'm wanting to set up a monitor for a smoking cabinet, consisting of 3 temp sensors (2 inside & 1 outside) and control/monitor a PWM fan. An adaptive fan controller that works under Arduino with the ESP32 (and others) This code works with 3-pin and 4-pin fans.

Main smoker control breakout board The devices in question are: olimex esp32-poe-iso, and a SANYODENKI San Ace 80 PWM fan The esp32 works at 3. We discuss the electric vehicle company, Rivian Automotive, along with their products and brand (not the stock). Use parts and wiring rated for the job, make sure the relay control wires stay well away from the 230V parts so they can't accidentally short when getting pinched or something (the relays should be placed inside the fan enclosure so only the safe control wires come out of the enclosure), only work on the 230V board when it's not powered, make ESP32 is a series of low cost, low power system on a chip microcontrollers with integrated Wi-Fi and dual-mode Bluetooth. However I couldn’t control zones as these are mechanical switches. With 4-pin fans it uses an adaptive technique to find the target the RPM you give it which allows the fan to make a best effort attempt at zeroing in on the desired RPM. In that case I only need 4 pins and that should work. Nov 24, 2024 · I'm using an ESP32 to control a fan through PWM. Just the fan needs to maintain the temp I'll take any help / direction one may offer. ( 2*duty cycle/one rotate) FG wire software pull up state I have a code that counts pulses using an interrupt function when a falling edge occurs, calculating the RPM. But only because I took one apart and discovered the design was a mains powered board with a 5V power supply that has the relays and triacs to manage the speed and direction of the AC fans. Connect a 12VDC power supply to the MOSFET, connect two wires from the PWM fan to the MOSFET. I can now control the RF fans, the IR audio equipment, the IR digital picture frame, and even unlock or lock or pop the trunk of my old 2013 Mazda 6 if its in the driveway.
