Turns the cooling system's fan on and off, depending on the connected system's detected temperature.
SKU 7100-FK007Item type: Assembled, KitCooling & heating
Description
| This board can turn your cooling system’s fan on and off depending on the detected temperature. With the on/off threshold set via the onboard trimmer, you can easily adjust it to the temperature you want. The board’s supply voltage ranges from 5 to 12 Vdc, with a maximum current draw of 500 mA. The LM35’s detectable temperature range is -55°C to +150°C; our circuit is able to detect temperatures from 2°C to +150°C. It’s also extremely versatile thanks to its MOSFET, voltage-level output. Its compact 36x42x20 mm size makes the board easy to install and use. Cool your electronic system efficiently and precisely with our LM35-based automatic cooling fan control board! |
