This little enclosure will hold an ESP32 and DHT22 snugly, for wifi climate monitoring in a nice small package. I recommend the vented, direct soldered lid. Even with the vents, if you use this without deep sleep or lower power mode, THE ESP WILL HEAT UP AND SKEW THE READING. Take a look at my code for deep sleep if you need to. I used a couple dabs of hot glue to hold the components to the case. I used Blynk to easily build a little dashboard for it that I can use on my phone for free, as pictured. You can find the code I used to do this here: https://github.com/light24bulbs/Blynk-DHT22-Climate-Sensor If you load it onto the ESP32 or 8266 with PlatformIO, it will automatically install the DHTesp library needed. Just swap in your WifI and blynk key and you're all set! You can build a GUI super easily with Blynk all on your phone.

M5CoreInk / M5StickC CO2 Sensirion sensor hat Source code and 3DPrint files for making a CO2 hat for M5CoreInk/M5StickC (or any ESP32 compatible board), this use a Sensirion SCD30 sensor for get CO2 values. Components Description Store link M5CoreInk M5Stack M5Stack Proto M5Stack Sensirion SCD30 Mouser M5StickC (compatible) M5Stack M5StickC Plus (compatible) M5Stack How to build it Firmware upload First of all, install PlatformIO with your favourite IDE (i.e. VSCode). Follow this instructions. Also, you may need to install git in your system. source code Clone the repo git clone https://github.com/hpsaturn/co2_m5coreink.git Via IDE (vscode) Connect the M5CoreInk or compatible board via USB. In Windows 10, drivers are installed automatically. I guess with other OS will be automatically installed too. Open cloned folder with your PlatformIO IDE and build & upload it. For details please see the documentation, but the process flow is more easy than Arduino IDE flow, but you can also import it to the Arduino IDE if you want. Via PlatformIO CLI After the clone, enter to directory and you can build and upload the current firmware from CLI: pio run --target upload 3D print Files

This is a Snap-Fit Case for the latest ESP32 Devkit v4, which has (compared to the Devkit v1) a smaller PCB without screwholes and where the antenna is sticking out. As far as i can tell, there are no other cases for the the Devkit v4, which i why i made a custom one. Features: hole for status LED two integrated buttons snap-fit top and bottom shells pin breakout supported (male & female) both STL's and FreeCAD files Configuration: fully enclosed (no pin breakout, just the bare board in a case) pin breakout to the bottom (breadboard compatibililty) pin breakout to the top (typically usefull for projects) ...just pick the corresponding top and bottom part for the case. Note: Wether you want to use male or female pin headers is your choice and most likely depends on you projects configuration and needs. The dimensions in the pin-breakout allow for both, as they are of the same size. The Snap-Fit mechanism requires some force to close and a spunger to being opened again. The tolerance is very small, so that even a small over-extrusion might make it to tight. Enjoy!

InfluxDB structures data using elements such as timestamps, field keys, field values, tags, etc.
