I have 2 sensors:
- 1 temperature sensor with steel head (provided by Seeeduino: seeedstudio.com/depot/temper … th=144_147);
- one temperature and relative humidity sensor - SHT11.
I consider that the SHT11 to be calibrated from the factory. I connected both sensors to a Seeeduino Stalker v2 and read the temperature values from both of them. Since they are placed close to each other I have expected that the value of temperature to be the same, but there is a difference of about 1 degree Celsius (quite high if I need them for monitoring the indoor ambient conditions).
For the thermistor I use the Steinhart-Hart to calculate the temperature value and for SHT11 the Seeeduino classes available on the Internet.
Anybody have any ideas about the precision of the thermistor?
