What is it?

The RadSens 2 is an universal module dosimeter-radiometer based on the tried and tested gas-discharge Geiger-Muller counter SBM 20. SMB20 tube included in delivery set. Dosimetr board supports different gas-discharge Geiger-Muller counters (like J305,M4011, STS-5 or others). The logic of the RadSens is based on the STM32 microcontroller. The data received from the Geiger counter is transmitted via the I2C interface. The device supports changing in the I2C address and turning off the high voltage generator (400V) to reduce power consumption. Fine-tuning of the counter sensitivity is supported.

What makes it special?

1. Ready to use

Dosimeter is tuned and SMB20 counter is included in delivery set. So you can use module from the box.

2. Measures three parameters

As an outbound I2C package, the RadSens board generates 3 values:

• Radiation intensity (μR / h) with an averaging algorithm - for accurate measurement of radiation over a long time period (500s)
• Radiation intensity (μR / h) with algorithm with a dynamic range of calculation time - for registering local sources of pollution
• The number of registered impulses since the last request to the I2C

3. Ready to use libraries, datasheet and friendly community

The radiation sensor based on RadSens board can work both in standalone mode and as part of an external Arduino, STM, Raspberry microcontroller or as part of your own device. To run the board you can use the sketch example or our libraries on GITHUB. Also you can join our community in Telegram: ClimateGuard_Community

4. Build-in led

Measuring background radiation in a standalone mode represents the radiation level by flashing the LED. With an increase in radiation, the blinking frequency will increase proportionally and vice versa.

5. Easy counter mount and unmount any counter

Tube (Geiger-Muller counter) could be mount on a special holders or soldered directly through holes in the board

6. Board support different counters

Supported Geiger-Muller counters: any with anode voltage 380 – 440 volts. Including but not limited to SBM20, J305,M4011, STS-5. Geiger-Muller counter not included in delivery set.
