One of the students in my IoT Computer Club (here in the UK) is working on a personal project to design and build a solar-powered weather station (that will be located in one of the school's gardens) to monitor and report air temperature, humidity and pressure. Here are the Objectives and list of i…

[image] dynamicdave: For the last three weeks we have been doing an experiment to see how long the Li-Ion battery will power the Wemos Always fun to do this type of experimentation. Have you run it with radio only switched off? I forget which mode that is now, but seem to recall significant p…

Yes - that's what we have been doing. Putting the Wemos D1 Mini into 'deepsleep' for a long period of time. We measured the current the Wemos takes during normal operation to be 170mA and when it goes into 'deepsleep' it goes down to 0.2mA. Quite a saving. We are using ESP Easy as the firmware and…

[image] dynamicdave: I'm hoping the student will document this part (soon). Such great fun being a student these days. The closest I got was taking the valves out of a television.

I've just posted a link (at the top of this thread) to the write-up for... "Putting the Wemos D1 Mini into 'deepsleep' to conserve the battery's charge". I hope you enjoy reading about Stage 2 of this project - hopefully more to come.

I've just posted a link (at the top of this thread) to the write-up for... " Switching on/off ancillary devices (e.g. BME280 and ADS1115 modules) to conserve energy". I hope you enjoy reading about Stage 3 of this project - hopefully more to come.

Hi David, I have just come across your post and found it very interesting. I myself have tinkered with all sorts of sensors, micro controllers for while now and more recently Node-Red, InfluxDB and Grafana. This is a great project that can be expanded as I have found myself, adding other sensors,…

@Cathprotech Martin...haven't you ever seen a weather rock ? :rofl:

So, they have already extended the sensors :wink:

Hi Martin, It's one student's project - however I've given him a fair amount of help. He's tackled the project in stages and has used some of the work he did with me last year. The brown lump is a 'stone' (very low-tech) to stop the cardboard box being blown away by the wind. I'll check if the T…

I hope you enjoy reading about Stage 4 of this project - hopefully more to come.
