Born again electronics guy here. Got my arduino a couple of days ago
and have done a lot of blinking leds lately
Moving on to temp sensing.
I got a LM335Z (datasheet
) and wondering
if anyone have used this sensor? Here is how I have connected the sensor:
I get a constant analogRead value of about ~1000 which probably
is very wrong.. Do my wiring look ok?
I'm trying to figure out how to convert the readings (when ok) to
a "human" value.. I should get 10mV per Kelvin but how do I map
the "a/d" value to voltage again to find out the temperature?
Voltage = analogRead(X)*5.0/1024.0; if using 5V as ref...
Anyone using this sensor and could post an example?
