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 or Linux kernel modules).
- air temperature & relative humidity measurement
- analog nonlinear sensor reading
- 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
