About the project

This project is a flexible integration for temperature monitoring: outdoors, in a swimming pool, glasshouse etc. It utilizes a TEMPer1f thermometer plugged into Raspberry Pi that’s connected to an AXIS camera via network. The temperature is displayed as a dynamic graphic overlay using CamOverlay App.

Technical Solution

TEMPer1f Sensor integration utilizes a micro app developed for this particular thermometer and additional compatible models. The thermometer is connected to a Raspberry Pi running CamScripter RPi with uploaded TEMPer1f Sensor package. CamScripter RPi forwards the data to an AXIS camera (AXIS M1135, P1375 etc.) featuring CamOverlay App so that the measured temperature can be displayed as a graphic overlay. The overlay becomes a part of the video stream and can therefore be managed in vms as a standard video source.

What do you need?

Hardware

• AXIS camera  e.g. AXIS M1135 (MSRP $419)
• TEMPer1f thermometer (approx. $25)
• Raspberry Pi (approx. $75)

Software

• CamScripter RPi
• CamOverlay App (MSRP $299)
• TEMPerf1 Sensor micro app

Price of solution: approx. $820

Tip:

Learn more about CamScripter RPi in this product sheet where we explain how to set up a Raspberry Pi to work with our app and how to prepare CamScripter RPi to work with micro apps of your choice.

Setup guide

Open your internet browser and type in the IP address of your Raspberry Pi to open CamScripter App UI. The IP address must be in the following format: http://localhost:52520/settings.html

Upload the TEMPer1f Sensor package.

Click “Start” to launch the micro application.

To set the thermometer up, open CamScripter App UI in your browser, and access the TEMPer1f Sensor via the gear button next to the installed thermometer package.

Here you can choose between Fahrenheit and Celsius temperature scales.

Custom Graphics

You can design your own widget or use our custom graphics for the micro app. The file is a part of the temper1fSensor.zip package available at GitHub.

To use our custom design, extract customGraphicsBackground.png file from the compressed file and import customGraphicsConfig.json (located at the same place) into CamOverlay App’s Custom Design settings.

The result

This is an extremely useful and cost-effective thermometer integration that can be applied across many scenarios and supports various graphics styles. Additionally, it’s both simple to set up and use.
