Just a few months ago, the government declared the following rules for manufacturing these tablets.
- While the manufacturer is allowed to maintain the temperature of the tablets between, -40 and -30 degrees Celsius, the temperature of the tablets should never remain between -33 and -30 degrees for longer than 20 minutes at a time.
- Also, the manufacturer should maintain a log of when the cooling chamber for the production of the tablets is opened.
- These rules should be implemented within a month of their declaration. Failing to comply would lead to cancellation of the pharmaceutical production permit.
While the government declared these rules to ensure that the medicine produced at all pharmaceutical companies, was good enough to be used by the general public, these rules put Mr. Nigel’s company in a bit of a pickle.
Implementing such stringent measurements was no easy task.
Connecting LM35 Sensor to the bolt
Step 1: Hold the sensor in a manner such that you can read LM35 written on it.
Step 2: In this position, identify the pins of the sensor as VCC, Output and Gnd from your left to right. VCC is connected to the grey wire, Output is connected to the white wire and Gnd is connected to the black wire.
Step 3: Using male to female wire connect the 3 pins of the LM35 to the Bolt Wifi Module as follows:
VCC pin of the LM35 connects to 5v of the Bolt Wifi module.
Output pin of the LM35 connects to A0 (Analog input pin) of the Bolt Wifi module.
Gnd pin of the LM35 connects to the Gnd.
Step 2: In this position, identify the pins of the sensor as VCC, Output and Gnd from your left to right. VCC is connected to the grey wire, Output is connected to the white wire and Gnd is connected to the black wire.

VCC pin of the LM35 connects to 5v of the Bolt Wifi module.
Output pin of the LM35 connects to A0 (Analog input pin) of the Bolt Wifi module.
Gnd pin of the LM35 connects to the Gnd.
Hardware Connections and supplying power
Hardware connections are made on the bolt wifi module and bold cloud is online.

Polynomial Regression
After deploying the changes, click on View Product. The temperature sensor hardware connections (with the bolt wifi module along with a power source) is kept in the refrigerator for about 2 hours and data is collected. This helps in setting boundaries for the temperatures.

Email sent when temperature crosses threshold
After setting the boundaries for the temperature, python code is written on Putty that will send an email if the temperature crosses a certain threshold.

z-score analysis for anomaly detection
Next, z-score analysis is performed to detect anomaly when someone opens the fridge. This will send an alert via email saying that someone has opened the fridge.
