The first group of contacts contains the following pins: The contacts are distributed into two groups, pitch 2.54 mm. There is also a special place on the board for mounting a DS18B20 temperature sensor. The circuit is equipped with resistors, which allow providing the required signal level. Interaction with other devices and exchanging information with them is done using the I2C interface with contacts SCL and SDA. temperature measurement) and read the module’s information. The presence of memory allows you to record various parameters (e.g. This allows you to save on power because, in the case of uninterrupted use will have to spend more voltage, even with the presence of the battery. The module is justified in cases where the data is read rather rarely, at intervals of a week or more.
