This post addresses the problem of servicing ESP based systems that have been installed. I have built systems where the ESP module is fixed, enclosed, and installed in a location that is difficult to get to once in place. As time progresses, so does the realization that some features will need to be updated on those installed ESP modules. Over The Air updates are the ideal way to update the modules without the hassle or downtime. Here is a detailed…
The ESP32-Cam module is an inexpensive platform that can be developed for many purposes. It does have some drawbacks. Compiling with the Arduino IDE can be much slower compared to native AVR platforms. Another issue is the “Brownout detector was triggered” message on the debug window. Slow compilation was covered in another post, https://www.cloudacm.com/?p=3998. This post will explore some ways to deal with the brownout fault. When the ESP32-Cam module boots, it will perform a series of checks and either…
This post will demonstrate how to build an outdoor domed camera using the ESP32-Cam module and various inexpensive parts. One of the limitations of the OV2640 camera module included with the ESP32-Cam is its low quality, especially in low light conditions. Attempts at adjusting the light sensitivity levels in software can only go so far, see the earlier post https://www.cloudacm.com/?p=3986 regarding those attempts. This post will focus more on hardware modifications to improve the image quality and for its use…
