This post will cover how to use the Melexis MLX90640 thermal array sensor with the ESP32-Cam module. The work presented here is based off of the work of others and their documented efforts. The reason for using the ESP32-Cam module is because of its low cost, small form factor, and its built in microSD storage. The Melexis MLX90640 thermal array sensor can provide a 32 x 24 pixel thermal image in either a 55 or 110 degree field of view…
Brian Lough created a video on YouTube titled “WiFiManager – An Essential ESP32 library!” This video pointed out that hard coded settings on the ESP32 can be a limitation. It went on to demonstrate this with wireless network connectivity and the inherent dependency when preset values are used. The solution rested on a library that gives the ESP32 the ability to operate as a WiFi access point and for the ESP32 to provide a web portal for an attached device….
There is a noticeable difference on how long it takes for a sketch for the ESP-32 to compile when using a Windows based system, versus using a Linux based system. Depending on the sketch, this difference can be up to 10 times, which could frustrate developers. The suggestions online point to anti virus as the cause, with disabling the anti virus or adding exceptions as the workaround. Others recommend using Visual Studio instead of the Arduino IDE. This post will…
