IC package help to control the FAN speed of around 24 exhaust fans using Wireless temperature sensor

Robson Jhon

I need to connect the exhaust fan which will be driven by Wireless Temperature Sensor set the limit in such a way that I can control the speed of the exhaust fan according to temperature readings,

 I 'll be able to work on code but I need IC package suggestion which is useful to control the inline Exhaust fans running with the AC power supply of 220V any circuit,

Any leads will be a great help.

    Hello Robson,

    Please clarify your design requirements. My understanding is that one wireless temperature sensor controls the speed of 24, 220 VAC fan motors continuously based on temperature. Example: Temp = 70 deg. F, all fans 100 RPM, Temp = 75 deg. F, all fans 120 RPM, Temp = 80 deg. F, all fans 130 RPM etc. Is that correct?

    exactly what I am looking, but the problem is I don't know what kind of IC packages will be useful to work with 24 Fan motors which are working at 220VAC

    Hi Robson,

    For the wireless portion of your design, you could use an IR Transmitter and receiver and our MSP430 MCU as shown here:

    IR.pdf

    Another alternative is something like our MSP430 based Low Power Wireless design slaa378d.pdf

    If your motor is a single phase, 220 VAC motor capable of variable speed operation, then the a DIAC/TRIAC speed control circuit can be used:


    If your 220 VAC motor is a 3-phase AC Induction motor, then you can use a C2000 DSP based speed control:

    See this http://www.ti.com/solution/ac-drive-power-stage-module for a generic block diagram that will allow you to select various subsystems and search for TI Products and reference designs. Note solutions for 3-phase motor drivers, temp sensors, processors etc.
