connect and meausure temp sensor with CR1000


mitsoulis Feb 13, 2012 02:22 PM

Hello ,

I need to use temp sensor tmp36 for meausuring high temperature of conductor. Tmp36 has three pins (wires):
one couple for input voltage (2.7V to 5.5V supply) and one for ouput voltage that is directly proportional to the temperature.

Connection: connect the couple of wires in 5v supply of Cr1000 datalogger and the middle wire at ex1 ?

Is it correct ?

meusure: use crbasic for programming.
To convert the voltage to temperature :

Temp in °C = [(Vout in mV) - 500] / 10

I really need some help for writing the correct program.
I would appreciate very much if you can advise me.

Not quite right. you need to use SE1 not EX1

connections
analog out pin to a single ended channel
Analog in pin to 5V
Ground pin to G

Use the VoltSE command to read the temp

VoltSe (Temp_mv,1,mV5000,1,1,0,250,1.0,0)
Temp_C = (Temp_mv - 500) / 10

Good Luck
