analog input of COL is DC 0-5V. if you want monitor temperature from 0 - 100 degrees, you can use DS18B20 connect to COL, COL support 5 channel of DS18B20 sensor. DS18B20 sensor detect temperature from -55----125 degrees, enough for you to use.
the analog inputs of COL work using the + 5vdc to power and receiving the 0-5v variation on the other pin?
if so I could use another DS18B20 giving gnd and + 5v separately, and sending the sengale in input to pin AI of col?
I have already purchased two of the sensors posted but I need them for something else
no, DS18B20 is digital output temperature sensor, not "analog output" type.
some sensor is 5v for power, some sensor is 12v for power. if you already have used 5pcs of DS18B20, now only can use analog type sensor for extend.

Hello,
I still have problems with analog sensors.
I bought DHTM-02S (analog sensor for temperature and humidity) and TMP36 (analog temperature sensor).
I connected the power supplies on the + 5v and gnd pins of COL. the analog output of the sensor on A1 + of COL.
with both sensors if I measure with the tester I have 0.6V on the analog channel.
I tried to change the coefficient from COL but I can't set them correctly.
is the analog output of the sensor on A1 + correct?
