Testing a homemade dosimeter
Today we have considered the most budget version of the dosimeter-radiometer. Out of curiosity, we ordered transparent plexiglass plates to make the device more convenient and descriptive. Potassium sulfate was used for testing. The fertilizer is rich in the radioactive isotope potassium-40, which actively emits beta radiation.

Required steps:
We need to solder all the elements and connect them. The SDA and SCL pins on the RadSens and the OLED screen must be connected to the D22 (SCL) and D21 (SDA) ports, which communicate via the I2C interface. Connect the rest according to the diagram below.
Before installing ESP32 tool you need to open preferences and type “https://dl.espressif.com/dl/package_esp32_index.json" in the Additional Boards Manager URL’s line
Extensions connection in the Arduino IDE for the ESP32 board is as follows:
Arduino -> Tools -> Board -> Board Manager -> type “ESP32” in the search bar.
After the installation, you need to specify “ESP32 Dev module” in the “Board” section.
Next, we need to select the specific board. To do this, go to the “Tools” tab, select the “Board” section, then select “ESP32 Dev Module” in the “ESP32 Arduino” subsection.
Almost done! Let's move on to the library installation.
To install the RadSens library, you need to follow almost the same steps:
Arduino -> Sketch -> Add Library -> Manage Libraries -> Type “RadSens” in the search bar.
Next, you need to install the GyverOLED library in the library manager.
Now we are ready to move on to development.

The standard level of radiation in a room is 15-20 μR/h. With direct contact of potassium sulfate, we get 32-39 μR/h, two times higher.
