Fan Controller With Temperature Sensor

The open hardware monitor is a free open source software that monitors temperature sensors fan speeds voltages load and clock speeds of a computer.

Blower fan di jakarta. Self monitoring analysis and reporting technology. The video below shows the fan speed changing when the temperature sensor is moved from cold water to hot water. The cpu temperature can be monitored by reading the core temperature sensors of intel and amd processors.

Temperature sensor lm35 senses the temperature and converts it into an electrical analog signal which is applied to the atmega328 microcontroller of the arduino uno board. Info and show hard disk temperaturesspeedfan supports scsi disks too. One senses the temperature by using humidity and temperature sensor namely dht11.

This is known as smart. So it is best to go for the automatic option via software to control the computers fan speed. Speedfan is a program that monitors voltages fan speeds and temperatures in computers with hardware monitor chips.

At the lowest level the speedfan hardware monitor software can access digital temperature sensors but its main feature is its ability to control fan speeds according to the temperatures inside your pc thus reducing noise. Second section reads the dht11 sensor modules output and extracts temperature value into a suitable number in celsius scale and control the fan speed by using pwm.

The analog value is converted into a digital value. You can hear the fan speed increase and see the readings changing on the arduino ide serial monitor. Speedfan can even access smart.

The remote sensor is a diode connected transistor typically a low cost easily mounted 2n3906 pnp type replacing conventional thermistor. With temperature sensorthermistor and fan failstop alarm these work well with our 4 wire cooling fan see listing title jmc fan 8025 12hb apw 12vdc 023a 4 wire speedtemperature control 80x80x25mm. Speed controller for four wire fan.

Well you can also change or control fan speeds manually but the process is a bit tricky. You need to connect a manual fan controller to your windows system with knobs and this will set fans to different speeds. And last part of system shows humidity and temperature on lcd and fan driver.

Thus the sensed values of the temperature and speed of the fan are displayed on the lcd. This simple project controls the speed of a fan based on the reading from a temperature sensor. Speedfan can even change the fsb on some hardware but this should be considered a bonus feature.
