Fan speed control using triac and arduino

After all, it’s just another component to deal with and anything extra adds additional cost to the system. Arduino Relay and fan control - LCDArduino. SPEED CONTROLLER: To control the speed of the fan a PWM (pulse width modulation) is used. Here we are not going to use a microcontroller. You can also control Fan speed with your TV remote using this Triac Dimmer The project ‘Temperature Controlled Fan using arduino’ is simply fabricated around arduino uno board and temperature sensor LM35. It can control those electrical equipment. PWM is a technique by using which we can control voltage. I should have been clearer with the PWM description - I meant PWM into a microcontroller to define the % AC output - then get the microcontroller to do the phase control - like the schematic I linked to, but with the micrcontroller as part of the module. As the width of the pulse decreases, firing angle of the triac increases and speed of the fan also increases. In your case Light or better we can say load is FAN. You can also control Fan speed with your TV remote using this Triac Dimmer circuit. The code listed under step 4 – i. How we can control the speed of AC 220 FAN using Arduino? Can I connect triac directly to microcontroller? I have to do a PIC microcontroller based mini project titled "temperature based fan speed controller. Instead, you use a low-voltage control signal from the Arduino Also do NOT mount the triac-fan board just yet! You are going to drill a hole at the right hand side later on and if you mount the triac-fan board it will just block your work! So wait! To sum up what I have done electrically: Joining bottom and top heater wires and replacing the built-in thermostat with the triac board. L. Far better speed stability is obtained by lowering the drive frequency from the standard 50Hz (or 60Hz). Construction of Remote Controlled Fan Regulator. Repeat Steps 5 to 11 infinitely. AC Fan speed control using Android mobile AC Fan & Motor Speed Controls . It is built around Arduino Uno board (Board1), 16×2 LCD (LCD1), temperature sensor LM35( IC1) and a few other components. As we know that by varying the firing angle of the TRIAC, the power applied through the load is controlled which is nothing but a concept of power control using TRIAC. using delay rather than a Timer. Circuit description. Switch OFF FAN 9. The light dimmer circuit or fan regulator circuit (either case, the circuit and design are the same, only difference is the output load to be varied, that is, fan or light) is used to control the brightness of the light or the speed of the fan according to our desire. A TRIAC is used as the control element to regulate the power going into the fan by varying its firing angle for different speed settings. I have a connected a 10K pot at adc input of MCU, as pot is rotated MCU sense the reading & accordingly control the phase.

We have used basic components to complete this task. Max. You may also have the PCBs made from any fabrication house too. 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. Control Resources is a leading manufacturer of AC motor speed control products that control motors, fans or pumps for a variety of industry applications with current rating up to 18 amps. Controlling a light kit is done using a separate wire from the wallbox to the fan. change method to control the speed of the FAN. In our case fanSpeed will have a value of 32 at tempMin and 255 at tempMax. Capacitor C1 2A104J is a Polyester film capacitor. I wanted to turn on/off and control the fan speed. The Arduino analogWrite() function produces a PWM signal with a frequency of about 490 Hz (on/off periods per The triac is fabricated by integrating two thyristors in an inverse parallel connection. For operational control over AC appliances like controlling the speed of a fan or dimming a light bulb, power electronics comes into the picture. Here's how! Circuits that operate at high voltages or at high currents cannot be controlled directly by an Arduino. Universal motor speed control by a In our case fanSpeed will have a value of 32 at tempMin and 255 at tempMax. So the circuit varies speed of AC motor by changing firing angle of TRIAC by applying PWM generated using IC555 connected in monostable mode.

This example based on the Arduino Example Fade sketch but modified to use timing instead of the delay() function */ The Study is aimed at controlling the speed of the fan automatically using Arduino, temperature, and humidity sensors. I found an answer for that since we are applying a linear control on the fan,if we we connect directly to the arduino,we would not be able to any voltage rather than 0 and 5 volts(it will act like a switch). In this example, a potentiometer (or other sensor) on analog input 0 is used to control the rotational speed of a stepper motor using the Arduino Stepper Library. To control the speed of an AC motor the cheapest and arguably the most efficient method would be using a triac or an anti-parallel SCR (thyristor) combination .

As many control functions are now carried out using microprocessors and/or logic circuits, there are also many triacs that accept logic signals for triggering rather than relying solely on traditional phase control techniques. If you decide to try to use this as a motor speed control, be prepared to make adjustments to the snubber circuit, and maybe add a heatsink to the triac itself. a TRIAC to control the router speed; a zero cross detector so we can do phase control; an Arduino to compare the target RPM with the real RPM and make changes using PID; You can order a PCB from osh park, and you'll need components spec'd in the BOM. The triac is fabricated by integrating two thyristors in an inverse parallel connection. C. power which can controlled with this dimmer depend on triac model. The proposed push button fan regulator circuit with display discussed in this post utilizes PWM control for controlling the speed of the fan and enables the user to do the same using an up, down push button arrangement.
