This temperature monitor IoT device uses ESP8266 and DS18B20 to report a remote temperature measurement to a mobile app and also sends an email to the user if the temperature goes below a set threshold.
IoT temperature monitor
To complete this project you will have to create three things
- Hardware – Basically you have to hook up the temperature sensor to the ESP8266 board and upload the Arduino code.
- Cloud device – Create the logic that drives the decision making using the IC2Cloud platform www.ic2cloud.com
- Mobile App – Create the mobile App using AppInventor to monitor and control your temperature appinventor.mit.edu
This project can be easily extended to monitor different thresholds and if combined with an actuator it can control a heating/cooling system.
Gary shares his ESP8266 controlled on/off switch for a lamp.
The first step is to find a case to house the parts in. I had an old TP-link router case that I used. It already had a two prong spring out 110v connections but any box will work. When planning your boxes figure out how your going to get the AC in and out of the box. A stop at your local bigbox hardware store should give you lots of idea. At a minimum a deepwall outlet/switch box will work but use your imagination. My project only uses 2 wire as thats what the case supported but if your planning on switching anything other than simple lights use a 3 wire system and include the ground.
If your not sure about what wires goes where take a look online on how you would add a simple manual switch to a circuit and just replace the switch with your device.

Jeremy Morgan‘s mini weather station is IoT enabled and uses Raspberry Pi to measure temperature, humidity, atmospheric Pressure, and light intensity in Lux. It is capable to send the results to Google Spreadsheet on your Google Drive or an ASP.Net Web API on your website.

Daniel Gilbert shares his experience of building the PinTin Nano, a Intel Edison powered portable password keeper.
PinTin Nano stores passwords for your accounts
With this instructable, I try to solve a problem everyone has: Passwords. Accounts. Logins. All the stuff you need to get into your favourite social media site, shopping site, blog or forum (they still exist, huh?). Now, there are several ways to control your accounts:
- Use always the same credentials: No. Never ever do that. Seriously. If your account gets hacked on one site, chance is that the hacker(s) will try the credentials on other, popular sites also. Don’t underestimate them. They are smart. Criminals, but smart.
- Use a software on every device: You can do that. And if you are lucky, this software will run forever on this device. But maybe, at some point, you will get rid of the devices. Uh-oh…
- Write them down: Yepp. You can do that. But – everyone who finds your book will be able to read your passwords. That wouldn’t be that great, right?
To solve all of this, I created a device called “The PinTin Nano”. It has it’s name from the fact that it’s a) pretty small and b) fits in a mint tin. I love that, because that makes the device easy to carry around.
