Chapter 5. Reading data from sensors

Modern sensors are manufactured as microelectromechanical systems (MEMS), in which very small intrinsic elements are deflected due to changes in a specific physical observable value—temperature, pressure, position in space, and so on. These changes are typically reported using electric signals, which are then transferred to appropriate electronics, which in turn process and interpret data to a form that is human-readable.

Obtaining data from sensors typically consists of reading raw byte values from appropriate memory registers. Thus, understanding raw data representation and organization is crucial for proper interpretation of information received from sensors. IoT software extensively uses low-level manipulations ...
