Geiger Radiation Detector

DESCRIPTION

This device is a meter power of radiation.

TECHNICAL DETAILS

In this project I use STM32 microcontroler.
Display is a graphical PCD8544 module with LED.
To create a high voltage path I decided to use PWM from STM32 and used voltage mutliplyer.
This device can charge from USB port and power from Li-ion cells.
To connect from world I use bluetooth 4.0 low energy power module.
Board have a reverse polarity circuit, 5 switches to controll and buzzer to prevent about high power radiation.
In this board you can use Nuclear sensor STS-5 (CTC-5) or LND7121.
In board you can find voltage dividers to monitor HV voltage path and Li-ion voltage monitoring.

Words to PCBWay

Thanks for your support because without you my project can be closed.
