FUNCTION BLOCK
FUNCTION

Produces an output voltage proportional to the temperature

  • The hotter it gets, the higher the voltage.
  • The Blok can be connected to get the reverse effect.

Supply Voltage (+V): 3 to 18 volts

CIRCUIT DETAILS
PCB LAYOUT

PCB: 25mm x 25mm

Assembly Instructions

+V
Vout
0V

NOTES:

  • To adjust the out voltage for a particular temperature, adjust the preset VR1 with a small screwdriver.
  • To convert this to a cold sensor (output voltage rises as it gets colder), connect the supply back to front - (the positive supply to 0v and the negative to +V). Never do this otherwise, unless specifically instructed to do so!

APPLICATIONS:

  • Temeprature monitoring
  • Environment controllers
  • Automatic cooling fan
  • Fridge failure alarm.
