This sensor seems popular with the arduino crowd, however I see that it is only rated to 155 deg C. I need a sensor capable of reading around the range of 200 deg C with the reliability of +- a few degrees. Do you think I can push the LM35 this high or it won't work? Any suggestions on other sensors?
A K or J type thermocouple will read these temperatures.
To interface these you will need a thermocouple interface
IC which is typically an SMD part.
I am working with the MAX31855 and K-type thermocouples.
I should have a sketch and schematic later this week.
I am using my PICOBEE board Loading...
to periodically measure temperature and transmit the timestamped data
to a PC. The MAX31855 has a 14bit ADC and has a resolution
of 0.25degC. Not sure of the accuracy yet.
Thermistors won't last 200 DegC and their housings aren't rated for that temperature. I would use thermocouple too. If you don't need sub DegC accuracy, you can find cheaper infrared remote temperature sensors too.
I just added a thermocouple + XBee application hint to my site -- Loading....
I interface a K-type thermocouple using the MAX31885KASA. I use the RTC on the PICOBEE
to periodically interrupt the uC. After an interrupt the temperature is read. The timestamped
data is transmitted using the XBEE.
