• Temperature Sensor Network, Part 4: Casing

  This is the fourth part of my temperature sensor network series, as explained in Part1. This part goes into the design of the casing and mounting the sensors. Casing There have been two design for the casing of the sensor. The first design placed the sensor inline with the rest of the dongle. . Sadly the flatcable running beneath the PCB antenna resulted in loss of link quality, and I received no packets from the other side of my house.

• Temperature Sensor Network, Part 3: Communication

  This is the third part of my temperature sensor network series, as explained in Part1. This part describes the network and communication setup. Connectivity To create a 802.15.4 border router, I used the RIOT-os border router example with the fifth dongle. There is some configuration that needs te be done: using usb-cdc and setting the correct network parameters. This configuration is included in the project on github (RiotTempsensor) For this border router to function, the device it is attached to needs to configure some networking things, and needs to run an udhcp daemon.

• Temperature Sensor Network, Part 2: Nodes

  This is the second part of my temperature sensor network series, as explained in Part1. This part also describes the used hardware. Requirements and features The basis of the whole temperature sensor network is of course the temperature sensor node. To design a temperature sensor node we need to first determine some requirements for the nodes. That is why I have made a list of requirements for the sensor nodes accourding to a MoSCoW principle.

• Temperature Sensor Network, Part 1: The Plan

  Well the next step of my 3d printer is taking quite a while. Luckily I had a different project that I can report on. I am trying to place a set of wireless temperature sensors in my home, without breaking the bank. The goal is to create 4 sensors to connect to my home assistant for less then €50.-. Initially the system may be powered by USB or other power adapters, but in the future I want to look into making them battery powered.
