Re: Analog Temperature Sensor Calibration

hi. when i use hot glue to stick the temperature sensor in the straw, does the temperature sensor need to touch the water? thank you for the help. The temperature sensor does not need to touch the water, however, I would advise you to not layer it too much, as that can skew the temperature readings...

Re: Analog Temperature Sensor Calibration

sorry for posting again but i am struggling with the coding because i am a beginner. i have done the coding for the LED lights but i am stuck on how i should approach the coding for temperature and voltage. does the analog input and temperature linear equation give me the voltage? i got confused on...

Re: Analog Temperature Sensor Calibration

First thing to check would be what values are you reading from your sensor without any conversion/calculation. They should be be between 8500 and 5000 for around 0 to 70 degrees. If you are not getting those values, something is wrong with the circuit wiring or the sensor. Did you double check the ...

Re: Analog Temperature Sensor Calibration

Hi, You have the correct approach and equations. What values of m and b did you calculate? 'm' should be around -0.0201 and 'b' around 175 (for that sensor with the TI innovator hub). If not close to those values, you must be reading incorrect values. For ex. around 2 degrees C, it should read appr...

Analog Temperature Sensor Calibration

Hi, I am new to this event, and I would like to ask how you are calibrating the temperature snesing device. What we have decided to do is use the TI Analog Temperature Sensor (LM19) and the TI Innovator Hub and calibrate the formula using the hot and cold water samples. What we did was get the analo...
