8 environmental sensors for Raspberry Pi that you can buy on Ebay

Over the past few years, environmental technology has improved and become very accessible to the final consumers. It is possible to find environmental sensors at a low cost which can be connected to low cost microprocessors like Raspberry Pi. Raspberry Pi has the capacity to monitor with readings over a long period of time and save them online.

Due to the low monetary investment, the evaluation of the environment can reach new borders like:

  • Higher number of readings in different parts of the basin of study area.
  • Higher number of readings (daily, hourly or even every minute).
  • Monitor changes in quality (spills)
  • Easy replacement in case of vandalism
  • Online registry of lectures, among others.

We have chosen the Ebay platform for having a wide variety of sensors, international free shipping and because if the product is not delivered within a certain period of time, the money is returned. You can also look in other similar platforms like Aliexpress, Aeropost, DX, etc.

Here we will show you some environmental sensors available to buy on Ebay. The list was made based on articles with free shipping. The prices presented were obtained on Dec. 15th 2016.

Hatari labs engagement

We are passionate about evaluating the environment and we are aware that it cannot be possible if we do not have monitoring records, methods, mathematical models and criteria. It is part of our responsibility to generate tutorials that will let you implement your own monitoring stations with Raspberry Pi and low cost microcontrollers.
