Students interested in building their very own Raspberry Pi temperature monitor or create other projects using a variety of different sensors. May be interested in a new project published to the Hackster.io website which uses a Raspberry Pi 3 Model B mini PC together with a variety of different temperature sensors and the Initial State application and cloud service to create an easy way to display data.
Although the Initial State monitoring services available from $10 per month free individual account are available for students with a .edu email address offering : Unlimited Visualizations, Unlimited Data Streams/Devices, 3-Months Data Retention, 60 API calls (600 events)/min, Real-Time Expressions and Sharing/Embeds.
“Securely stream time series data to your account from anything that can make an HTTPS request. You can rest assured that your data is safe as Initial State continuously provides a secure, sophisticated infrastructure to ensure confidentiality, integrity, and availability of our systems and your data.”
If you’re interested in learning more about the different Raspberry Pi operating systems available check out our comprehensive guide. Sensors used in the Raspberry Pi temperature monitor project include the DSB18B20, DHT22, and Raspberry Pi Sense HAT.
– DHT22 — This temperature and humidity sensor has temperature accuracy of +/- 0.5 C and a humidity range from 0 to 100 percent. It is simple to wire up to the Raspberry Pi and doesn’t require any pull up resistors.
– DSB18B20 — This temperature sensor has a digital output, which works well with the Raspberry Pi. It has three wires and requires a breadboard and resistor for the connection.
– Sense HAT — This is an add on board for Raspberry Pi that has LEDs, sensors, and a tiny joystick. It connects directly on to the GPIO on the Raspberry Pi but using a ribbon cable gives you more accurate temperature readings.
