Tiny particle sensor node with decorative case

lucky-resistor-7

Lucky Resistor published a new build:

This article is about a small sensor node with a decorative case. It is based on the Raspberry Pi Zero W board with a custom sensor shield on top.
I publish all hardware files for a simple version of the sensor, so you should be able to build this kind of sensor nodes and use it to monitor anything you like. You can also extend/modify the design easily with additional sensors. Nevertheless, the case lid design is based around the Plantower PMSA003 particle sensor. It has all required air vents for this use.

A high-resolution sensor node

A high-resolution sensor node from JeeLabs:

The JeeNode Zero is intended as sensor node in a Wireless Sensor Network. This requires:

  • a sensor we can read out periodically, such as the BME280
  • being able to sleep with a very low current, as recently described
  • the ability to run the node unattended, i.e. without FTDI cable
  • formatting and sending the collected sensor readings over RF

So far, all development has been performed through FTDI. To run unattended, we’ll need to cut that umbilical cord and make the node start up by itself from a battery.
