How To attach Temperature Sensor

Other Hardware Sensors
1

Hello community,

I'm using the arduino UNO board and a KTY81/222 temperature sensor (just two pins).

  1. How do I connect the temperature sensor to my board?
  2. How do I get some data from it?

I’m very grateful for any help.

Hello myRobot guy,

Look this figure and connect it to Analog input pin of UNO.

(Vcc 5+)--+-->2.7k--+-->kty81-222-->(GND)
| |
+->100nF--+-----> ADC0 (Analog Port 0)

I hope you got your answers.

Search the forum for 'voltage divider' - that should turn up some examples

Thank's for your replies.

Won't work for me.
It's very frustrating...

Open this link you ll get your ans:

it shows that connect your sensor's pin1 to GND and another pin2 to 2.7K Ohm resistor. Another terminal of this resistor is connected to Vcc (+5V) supply. Now connect 100nF capacitor parallel to Resistor. So connect a wire to pin2 and Anlaog Port0-A0 pin.
