TTGO Camera

A while back I ordered a TTGO camera from Ali Express. It came today and it is lovely. It is similar to the ESP32 webcam that I bought a while back, but it has a PIR sensor and a BME 280 environmental sensor along with a nifty OLED display.

It is supplied with firmware that sets it up as an Access Point. If you connect to it you can view the image and control it from the web page that it serves out. I think it is running the same software as I loaded into the earlier device, but it is nice to have it on the device at the end.

It works extremely well. I’ve printed a little case for it from a design I found on Thingiverse and now I’m looking forward to having a play. They say it can do facial recognition, which is very interesting, and it might be a good device for our Humber Care Tech Challenge entry.

Update: I’ve found a nice blog post here on how to use this device as a fridge alarm. This shows how to put the processor to sleep and trigger wakeup using the PIR sensor.
