TMP36 Test

TMP36 Temperature Sensor

Kirk Schichl

Description and Use

        

            The TMP36 are low voltage temperature sensors that provide a voltage output that is linearly proportional to the Celsius temperature, and ranges from -40°C to +125°C. This device is intended for single-supply operation from 2.7 volts to 5.5 volts at maximum. The supply current runs well below 50μA, which provides very low self-heating. 

Pin Configuration:

Test Summary: Arduino with TMP36 Temperature Sensor.

Description:

The testing of the Arduino Nano working with the TMP36 temperature sensor was done in lab. The TMP36 was connected to the Nano with a voltage supply of 5 volts while the Nano reads the voltage output. The output voltage can be converted to temperature easily using the scale factor of 10 mV/°C. The Arduino code would read the output voltage and convert it into degrees Celsius. What we did to make sure the code was working with the TMP36 sensor was to touch the sensor and notice any changes in the temperature readings. This was successful.

Code for Arduino:

Integration into Payload:

This component will be soldered directly onto a printed circuit board and connected via wires outside of the insulated payload to record atmospheric temperatures. The printed circuit board connects all the instruments including the Arduino.

Goals:

The goals of the test were to get the Arduino successfully working with the TMP36 temperature sensor. Also, making sure the code written for the Arduino was perfect and able to measure accurate temperature readings. This is key to the overall success of the weather balloon to accurately measure temperatures.

Results:

The test went well when we compared our numbers to a thermometer in the room. The temperatures TMP36 was reading was around 19°C-22°C when the temperature in the room was around 20°C at the time.
