A differenza di altri sensori, lm335 ha unuscita lineare. So, if youre using that sensor you need to uncomment the following line. Lmx35, lmx35a precision temperature sensors datasheet rev. If youre using the lm335 sensor, you also need a variable to hold the temperature in kelvin. It has a breakdown voltage directly proportional to absolute temperature at. Operating as a 2terminal zener, the lm5 has a breakdown voltage. There are two ways to use lm335 sensor, one is as basic temperature sensor and another is calibrated. An accurate sensor with a comparator switch is great, and you can use trimpots to calibrate such a circuit against a known source, but using the lm335 as a sensor will feed a usable number directly into code for arduino, raspberry pi, or other programmables, in a way few other sensors can. Today im showing you how to wire up and use a lm335 temp sensor that reads in kelvin.

Physical data acquisition and pwm signal generation using a. Differential temperature sensor 569814 variable offset thermometer 569815 adjust for zero with sensor at 0c and 10t pot set at 0c adjust for zero output with 10t pot set at 100c and sensor at 100c output reads difference between temperature and dial setting of 10t pot. Lm35 is a precision centigrade temperature sensor manufactured by texas instruments. The single point calibration works because the output of the lm5, lm235, lm335 is proportional to the absolute temperature with the extrapolated output of sensor going to 0v. View lab report 282102610practica1sensoresdetemperaturaintergrado lm335.

It can be used for any type of temperature sensing in range of 40c to 100c. Initialize a serial communication at a baud rate of 9600. All you have to do is take the output reading and divide it by 10 in order to get the temperature output reading. Lm35 precision centigrade temperature sensors datasheet rev. The lm5 series are precision, easilycalibrated, integrated circuit temperature sensors.
