I used an LCD shield to display the current temperature and speed of the fan, but you can use the circuit without the LCD display. You also need to select the transistor by the type of fan that you ...

AHT10 Temperature & Humidity Sensor. ... Logic Level Shifter Circuit: The logic level shifter consists a 10Kx4 SMD resistor array network (103) and a 6-pin dual N-Channel MOSFET chip. ... I’m happy I ...

This isn’t about connecting a temperature sensor in your Arduino. ... This is an interesting idea. I would be weary of the long term accuracy as RC circuits are known to drift.

Built around the Arduino Pro Micro and an Adafruit TFT color LCD, ... an IR temperature sensor, and an arduino. ... location to mount the IR temperature sensor. The control circuit uses PWM to ...
