GGreg20_V3 NodeMCU firmware Lua code example

This is a simple Lua script example for GGreg20_V3 / GGreg20_V1 ionizing radiation detector module with SBM-20 GM tube working under NodeMCU firmware on ESP32 / ESP8266

This script is based on alterstrategy.lab (c) RadCounter - a full fledged LUA driver library module for radiation pulse counters under NodeMCU firmware.

Developed in 2022 by IoT-devices LLC, Kyiv, Ukraine with special alterstrategy.lab permission

Usage

To get results:

1. Run the script

dofile('ggreg20_v3_nodemcu_firmware_lua_example.lua')

2. Run init() function with parameters

init(3, 1, 60000)

3. Wait for 1 minute (after first pulse from GGreg20_V3) OR just run read() function to get current values

read()
-- or:
ma5_rad_lvl, cpm, minutes = read()

The Full fledged driver

If you want to obtain ready-to-use and well commented Lua code with:

• debug output mode,
• calculation of minimum / maximum instantaneous levels,
• accumulated dose of radiation,
• low-pass and hi-pass debounce filtering,
• UNKNOWN / NORMAL / HIGH / DANGER event handling

as a complete Lua module with public methods registration, you may find it here: https://alterstrategy.com/product/radcounter/
