+This module provides access to the DS18B20 1-Wire digital thermometer. Note that NodeMCU offers both a C module (this one) and [a Lua module for this sensor](https://github.com/nodemcu/nodemcu-firmware/tree/dev/lua_modules/ds18b20). See [#2003](https://github.com/nodemcu/nodemcu-firmware/pull/2003) for a discussion on the respective merits of them.
