This device is based on ATtiny13A with closed-source firmware with author's

features. It is not DS2437 or its replacement, but it is developed to be

possible to use it with a lot of software written for DS2437

(such as [OWFS](https://github.com/owfs/owfs) or Linux kernel modules).

## Main usage

* air temperature & relative humidity measurement

* analog nonlinear sensor reading

## Key features

* built-in NTC thermistor

* support for cheap HR202L/HR31 resistive humidity sensor (including alternating current & temperature compensation)

* one alalog input for user's sensor

* three optional conversion tables with linear interpolation between points

* sensors calibration at any time by modifying conversion tables in EEPROM

* ready to use results

## Example of web-interface
