What is it RadSens?

The RadSens is an universal module dosimeter-radiometer based on the tried and tested gas-discharge Geiger-Muller counter SBM 20-1.

• SMB 20-1 tubes included in the 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, turning off the high voltage generator (400V) to reduce power consumption and fine-tuning of the counter sensitivity is supported.

What makes it special?

1. Size

Dosimeter has a size of only 89 х 21 х 16 mm. Counter is mounted directly on the board. So you can easily place the module in any junction box.

2. Ready for use

Dosimeter is tuned and SMB20-1 counter is included in the delivery set. So you can use modules from the box.

3. Three measurement 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

4. Ready to use libraries, data sheet and friendly community

The radiation sensor based on the RadSens board works in stand-alone mode, as part of an external microcontroller Arduino, STM, Raspberry or as part of your own device. To run the board, you can use an example sketch or our libraries on GITHUB.

5. Built-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.

6. Easy counter mount and unmount any counter

Tube (Geiger-Muller counter) could be changed and soldered directly through holes in the board

7. Board support different counters

Supported Geiger-Muller counters: any with anode voltage 380 – 440 volts.
