A People Counter with Raspberry Pi and Ubidots

+

· The script consists of a loop that checks the state of the pin 7 (the motion sensor). If it reads a "1", meaning that there was movement, then it increments the "peoplecount" variable and waits seconds so the motion sensor goes back to normal. This is done 10 times, making sure there is at least 1 second between each cycle, then it sends the total sum of …

Reading out a Flow Meter/Water Flow Sensor on the Raspberry Pi

+

· Reading out a Flow Meter/Water Flow Sensor on the Raspberry Pi. In projects such as the automated greenhouse, it is important to know how much water, for example, reaches the plants for irrigation. There is also an inexpensive variant that we can quickly read using the Python programming language and also integrate into our smart home system.

Counting Objects In Movement Using Raspberry PI OpenCV ...

+

As it was said before, this project consists in a counter of objects in movement using computer vision (in this case, OpenCV running on Raspberry PI). About this counting, this project can count how much objects get in and out from the monitored zone. For instance, this kind of monitoring can be very useful in retail stores. This can be very ...

Monitor air quality with a Raspberry Pi Raspberry Pi

+

· Add a sensor and some Python 3 to your Raspberry Pi to keep tabs on your local air pollution, in the project taken from Hackspace magazine issue 21. Air is the very stuff we breathe. It’s about 78% nitrogen, 21% oxygen, and 1% argon, and then there’s the assorted ‘other’ bits and pieces – many of which have been spewed out by humans and our related machinery. Carbon dioxide is ...

Particle Raspberry PI Projects

How To Measure Particulate Matter With a Raspberry Pi ...

+

· Reading data on the Raspberry Pi. We first create an instance of the sensor and then read the sensor every 5 minutes for 30 seconds. These values can of course be adjusted. Between the measuring intervals, we put the sensor into a sleep mode to increase its life span (according to the manufacturer, the lifetime is approx. 8000 hours).
