Process

In going about creating this circuit, I gathered the components described in the tutorial walk-through. After some initial issues identifying the right parts, I realized that the lab didn’t have the recommended 10 nF capacitor for this temperature sensing circuit. To overcome this issue, I used four .04 uF capacitors in series to get the desired effect. Even then, my temperature readings were way off, reading at -55 degrees Fahrenheit. After some consultation with the TAs, we saw that my sensor wasn’t being powered by anything and couldn’t accurately sense the environment in the lab. I needed an additional jumper wire connection at A2 on the breadboard to power the sensor. With this final connection, I started getting credible temperature readings within a range of 55-75 degrees Fahrenheit on the Particle app. I lastly went back and added an LED light to show the user that the circuit is connected to the internet and actively transmitting data.
