mLink TMP36 Temperature Sensor

The mLink TMP36 module is a tiny serial (I2C/IIC) device that includes a precision TMP36 temperature sensor. This allows the module to measure temperatures over a wide range of -40 to 125oC. The module continuously takes measurements from the TMP36 sensor and provides the result as a temperature in degrees centigrade via its serial I2C interface. It is compatible with other mLink or standard I2C modules allowing you to daisy-chain several different types of modules together using only the two I2C pins of your microcontroller. Its default I2C address can be changed via software so that multiple TMP36 modules can be connected to one microcontroller.


For Arduino users you can use the mLink library (see below) to control any type of mLink module. Only one single instance of the library is needed to control multiple types of mLink modules resulting in very little resources overhead and therefore making it great for Arduinos with small amounts of memory and pin counts.

For Raspberry Pi users we have a Python module which can be installed via pip or downloaded and installed directly from our forum. Please see the mLink Python forum thread for requirements and download link here: viewtopic.php?f=131&t=3062&p=8592#p8592

Arduino Connection Example:






Because the modules use an I2C interface this also means multiple modules can controlled from a single Arduinos I2C interface simply by daisy-chaining them together. Note to control multiple mLink modules of the same type requires changing the default I2C address of the additional modules. See mLink Library Quick Start Guide for how to do this.
