  • Temperature logging update

    I think I now have my Raspberry Pi powered temperature logger working to where I wanted it to be. My hand-built temperature logging had a chart that tracked sensor temperatures over time, so that was the least I wanted to replicate using a Raspberry Pi…

  • Sometimes it's not actually a glitch.

    Have you ever had one of those moments where the data just looks out of place? The above chart is from 2 temperature sensors. The one shown in green is connected to my hummingbird feeder (insulated, with a small USB-powered hand-warmer heater on it),…

  • Over the Air (OTA) Programming of ESP8266 - Part II

    OTA Firmware Updates using an HTTP server In my previous Blog: Over the Air (OTA) Programming of ESP8266 - Part I , I described how to update ESP8266 firmware OTA, using the Arduino IDE to connect to the ESP8266 via a "network port". I pointed out that…

  • Power Consumption of a Wemos D1 mini ESP8266 - Long Term Test 3

    Having returned from my holiday in the winter sun , I removed the battery from its holder and set about fitting the XH2-2.54mm female connector to the battery holder leads. I then modified the sketch to reduce the drift in the sleep time which is evident…

  • Power Consumption of a Wemos D1 mini ESP8266 - Long Term Test 2

    Recap I n a previous blog: https://www.element14.com/community/people/neilk/blog/2019/02/17/esp8266-power-consumption-further-studies I observed that the power consumed by the Wemos d1 mini during deep sleep was pretty negligible - about 22.7 mAh over…

  • Power Consumption of a Wemos D1 mini ESP8266 - Long Term Test 1

  • Power Consumption of a Wemos D1 mini ESP8266

    Background I'm working on a long term project (several years now, if I'm honest!), to provide environmental monitoring and possibly some environmental control for my greenhouses. I've already investigated temperature monitoring using DS18B20 probes, which…
